  • Custom validation works in development but not in unit test

    - by Geolev
    I want to validate that at least one of two columns have a value in my model. I found somewhere on the web that I could create a custom validator as follows: # Check for the presence of one or another field: # :validates_presence_of_at_least_one_field :last_name, :company_name - would require either last_name or company_name to be filled in # also works with arrays # :validates_presence_of_at_least_one_field :email, [:name, :address, :city, :state] - would require email or a mailing type address module ActiveRecord module Validations module ClassMethods def validates_presence_of_at_least_one_field(*attr_names) msg = attr_names.collect {|a| a.is_a?(Array) ? " ( #{a.join(", ")} ) " : a.to_s}.join(", ") + "can't all be blank. At least one field must be filled in." configuration = { :on => :save, :message => msg } configuration.update(attr_names.extract_options!) send(validation_method(configuration[:on]), configuration) do |record| found = false attr_names.each do |a| a = [a] unless a.is_a?(Array) found = true a.each do |attr| value = record.respond_to?(attr.to_s) ? record.send(attr.to_s) : record[attr.to_s] found = !value.blank? end break if found end record.errors.add_to_base(configuration[:message]) unless found end end end end end I put this in a file called lib/acs_validator.rb in my project and added "require 'acs_validator'" to my environment.rb. This does exactly what I want. It works perfectly when I manually test it in the development environment but when I write a unit test it breaks my test environment. This is my unit test: require 'test_helper' class CustomerTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end test "customer not valid" do puts "customer not valid" customer = Customer.new assert !customer.valid? assert customer.errors.invalid?(:subdomain) assert_equal "Company Name and Last Name can't both be blank.", customer.errors.on(:contact_lname) end end This is my model: class Customer < ActiveRecord::Base validates_presence_of :subdomain validates_presence_of_at_least_one_field :customer_company_name, :contact_lname, :message => "Company Name and Last Name can't both be blank." has_one :service_plan end When I run the unit test, I get the following error: DEPRECATION WARNING: Rake tasks in vendor/plugins/admin_data/tasks, vendor/plugins/admin_data/tasks, and vendor/plugins/admin_data/tasks are deprecated.

  • How to setup custom DNS with Azure Websites Preview?

    - by husainnz
    I created a new Azure Website, using Umbraco as the CMS. I got a page up and going, and I already have a .co.nz domain with www.domains4less.com. There's a whole lot of stuff on the internet about pointing URLs to Azure, but that seems to be more of a redirection service than anything (i.e. my URLs still use azurewebsites.net once I land on my site). Has anybody had any luck getting it to go? Here's the error I get when I try adding the DNS entry to Azure (I'm in reserved mode, reemdairy is the name of the website): There was an error processing your request. Please try again in a few moments.

  • How to determine whether a class has a particular templated member function?

    - by Aozine
    I was wondering if it's possible to extend the SFINAE approach to detecting whether a class has a certain member function (as discussed here: "Is there a Technique in C++ to know if a class has a member function of a given signature?" http://stackoverflow.com/questions/87372/is-there-a-technique-in-c-to-know-if-a-class-has-a-member-function-of-a-given-s ) to support templated member functions? E.g. to be able to detect the function foo in the following class: struct some_class { template < int _n > void foo() { } }; I thought it might be possible to do this for a particular instantiation of foo, (e.g. check to see if void foo< 5 >() is a member) as follows: template < typename _class, int _n > class foo_int_checker { template < typename _t, void (_t::*)() > struct sfinae { }; template < typename _t > static big test( sfinae< _t, &_t::foo< _n > > * ); template < typename _t > static small test( ... ); public: enum { value = sizeof( test< _class >( 0 ) ) == sizeof( big ) }; }; Then do foo_int_checker< some_class, 5 >::value to check whether some_class has the member void foo< 5 >(). However on MSVC++ 2008 this always returns false while g++ gives the following syntax errors at the line test( sfinae< _t, &_t::foo< _n > > ); test.cpp:24: error: missing `>' to terminate the template argument list test.cpp:24: error: template argument 2 is invalid test.cpp:24: error: expected unqualified-id before '<' token test.cpp:24: error: expected `,' or `...' before '<' token test.cpp:24: error: ISO C++ forbids declaration of `parameter' with no type Both seem to fail because I'm trying to get the address of a template function instantiation from a type that is itself a template parameter. Does anyone know whether this is possible or if it's disallowed by the standard for some reason? EDIT: It seems that I missed out the ::template syntax to get g++ to compile the above code correctly. If I change the bit where I get the address of the function to &_t::template foo< _n > then the program compiles, but I get the same behaviour as MSVC++ (value is always set to false). If I comment out the ... overload of test to force the compiler to pick the other one, I get the following compiler error in g++: test.cpp: In instantiation of `foo_int_checker<A, 5>': test.cpp:40: instantiated from here test.cpp:32: error: invalid use of undefined type `class foo_int_checker<A, 5>' test.cpp:17: error: declaration of `class foo_int_checker<A, 5>' test.cpp:32: error: enumerator value for `value' not integer constant where line 32 is the enum { value = sizeof( test< _class >( 0 ) ) == sizeof( big ) }; line. Unfortunately this doesn't seem to help me diagnose the problem :(. MSVC++ gives a similar nondescript error: error C2770: invalid explicit template argument(s) for 'clarity::meta::big checker<_checked_type>::test(checker<_checked_type>::sfinae<_t,&_t::template foo<5>> *)' on the same line. What's strange is that if I get the address from a specific class and not a template parameter (i.e. rather than &_t::template foo< _n > I do &some_class::template foo< _n >) then I get the correct result, but then my checker class is limited to checking a single class (some_class) for the function. Also, if I do the following: template < typename _t, void (_t::*_f)() > void f0() { } template < typename _t > void f1() { f0< _t, &_t::template foo< 5 > >(); } and call f1< some_class >() then I DON'T get a compile error on &_t::template foo< 5 >. This suggests that the problem only arises when getting the address of a templated member function from a type that is itself a template parameter while in a SFINAE context. Argh!

  • Saving to SharedPreferences from custom DialogPreference

    - by Ronnie
    I've currently got a preferences screen, and I've created a custom class that extends DialogPreference and is called from within my Preferences. My preferences data seems store/retrieve from SharedPreferences without an issue, but I'm trying to add 2 more sets of settings from the DialogPreference. Basically I have two issues that I have not been able to find. Every site I've seen gives me the same standard info to save/restore data and I'm still having problems. Firstly I'm trying to save a username and password to my SharedPreferences (visible in the last block of code) and if possibly I'd like to be able to do it in the onClick(). My preferences XML that calls my DialogPreference: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory> <com.rone.optusmon.AccDialog android:key="AccSettings" android:title="Account Settings" android:negativeButtonText="Cancel" android:positiveButtonText="Save" /> </PreferenceCategory> </PreferenceScreen> My Preference Activity Class: package com.rone.optusmon; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.os.Bundle; import android.preference.Preference; import android.preference.Preference.OnPreferenceClickListener; import android.preference.PreferenceActivity; import android.view.KeyEvent; public class EditPreferences extends PreferenceActivity { Context context = this; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); } } My Custom DialogPreference Class file: package com.rone.optusmon; import android.content.Context; import android.content.DialogInterface; import android.content.SharedPreferences; import android.preference.DialogPreference; import android.preference.PreferenceManager; import android.text.method.PasswordTransformationMethod; import android.util.AttributeSet; import android.view.View; import android.widget.CheckBox; import android.widget.CompoundButton; import android.widget.CompoundButton.OnCheckedChangeListener; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.TextView; import android.widget.Toast; public class AccDialog extends DialogPreference implements DialogInterface.OnClickListener { private TextView mUsername, mPassword; private EditText mUserbox, mPassbox; CharSequence mPassboxdata, mUserboxdata; private CheckBox mShowchar; private Context mContext; private int mWhichButtonClicked; public AccDialog(Context context, AttributeSet attrs) { super(context, attrs); mContext = context; } @Override protected View onCreateDialogView() { @SuppressWarnings("unused") LinearLayout.LayoutParams params; LinearLayout layout = new LinearLayout(mContext); layout.setOrientation(LinearLayout.VERTICAL); layout.setPadding(10, 10, 10, 10); layout.setBackgroundColor(0xFF000000); mUsername = new TextView(mContext); mUsername.setText("Username:"); mUsername.setTextColor(0xFFFFFFFF); mUsername.setPadding(0, 8, 0, 3); mUserbox = new EditText(mContext); mUserbox.setSingleLine(true); mUserbox.setSelectAllOnFocus(true); mPassword = new TextView(mContext); mPassword.setText("Password:"); mPassword.setTextColor(0xFFFFFFFF); mPassbox = new EditText(mContext); mPassbox.setSingleLine(true); mPassbox.setSelectAllOnFocus(true); mShowchar = new CheckBox(mContext); mShowchar.setOnCheckedChangeListener(mShowchar_listener); mShowchar.setText("Show Characters"); mShowchar.setTextColor(0xFFFFFFFF); mShowchar.setChecked(false); if(!mShowchar.isChecked()) { mPassbox.setTransformationMethod(new PasswordTransformationMethod()); } layout.addView(mUsername); layout.addView(mUserbox); layout.addView(mPassword); layout.addView(mPassbox); layout.addView(mShowchar); return layout; // Access default SharedPreferences SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); } public void onClick(DialogInterface dialog, int which) { mWhichButtonClicked = which; // if statement to set save/cancel button roles if (mWhichButtonClicked == -1) { Toast.makeText(mContext, "Save was clicked", Toast.LENGTH_SHORT).show(); mUserboxdata = mUserbox.getText(); mPassboxdata = mPassbox.getText(); // Save user preferences SharedPreferences settings = getDefaultSharedPreferences(this); SharedPreferences.Editor editor = settings.edit(); editor.putString("usernamekey", (String) mUserboxdata); editor.putString("passwordkey", (String) mPassboxdata); } else { Toast.makeText(mContext, "Cancel was clicked", Toast.LENGTH_SHORT).show(); } } } In my SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); line, Eclipse says "The method getDefaultSharedPreferences(AccDialog) is undefined for the type AccDialog". I've attempted to change the context to my preferences class, use a blank context and I've also tried naming my SharedPrefs and using "getSharedPreferences()" as well. I'm just not sure exactly what I'm doing here. As I'm quite new to Java/Android/coding in general, could you please be as detailed as possible with any help, eg. which of my files I need to write the code in and whereabouts in that file should I write it (i.e. onCreate(), onClick(), etc) Edit: I will need to the preferences to be Application-wide accessible, not activity-wide. Thanks

  • How should I delete a child object from within a parent's slot? Possibly boost::asio specific.

    - by kaliatech
    I have written a network server class that maintains a std::set of network clients. The network clients emit a signal to the network server on disconnect (via boost::bind). When a network client disconnects, the client instance needs to be removed from the Set and eventually deleted. I would think this is a common pattern, but I am having problems that might, or might not, be specific to ASIO. I've tried to trim down to just the relevant code: /** NetworkServer.hpp **/ class NetworkServices : private boost::noncopyable { public: NetworkServices(void); ~NetworkServices(void); private: void run(); void onNetworkClientEvent(NetworkClientEvent&); private: std::set<boost::shared_ptr<const NetworkClient>> clients; }; /** NetworkClient.cpp **/ void NetworkServices::run() { running = true; boost::asio::io_service::work work(io_service); //keeps service running even if no operations // This creates just one thread for the boost::asio async network services boost::thread iot(boost::bind(&NetworkServices::run_io_service, this)); while (running) { boost::system::error_code err; try { tcp::socket* socket = new tcp::socket(io_service); acceptor->accept(*socket, err); if (!err) { NetworkClient* networkClient = new NetworkClient(io_service, boost::shared_ptr<tcp::socket>(socket)); networkClient->networkClientEventSignal.connect(boost::bind(&NetworkServices::onNetworkClientEvent, this, _1)); clients.insert(boost::shared_ptr<NetworkClient>(networkClient)); networkClient->init(); //kicks off 1st asynch_read call } } // etc... } } void NetworkServices::onNetworkClientEvent(NetworkClientEvent& evt) { switch(evt.getType()) { case NetworkClientEvent::CLIENT_ERROR : { boost::shared_ptr<const NetworkClient> clientPtr = evt.getClient().getSharedPtr(); // ------ THIS IS THE MAGIC LINE ----- // If I keep this, the io_service hangs. If I comment it out, // everything works fine (but I never delete the disconnected NetworkClient). // If actually deleted the client here I might expect problems because it is the caller // of this method via boost::signal and bind. However, The clientPtr is a shared ptr, and a // reference is being kept in the client itself while signaling, so // I would the object is not going to be deleted from the heap here. That seems to be the case. // Never-the-less, this line makes all the difference, most likely because it controls whether or not the NetworkClient ever gets deleted. clients.erase(clientPtr); //I should probably put this socket clean-up in NetworkClient destructor. Regardless by doing this, // I would expect the ASIO socket stuff to be adequately cleaned-up after this. tcp::socket& socket = clientPtr->getSocket(); try { socket.shutdown(boost::asio::socket_base::shutdown_both); socket.close(); } catch(...) { CommServerContext::error("Error while shutting down and closing socket."); } break; } default : { break; } } } /** NetworkClient.hpp **/ class NetworkClient : public boost::enable_shared_from_this<NetworkClient>, Client { NetworkClient(boost::asio::io_service& io_service, boost::shared_ptr<tcp::socket> socket); virtual ~NetworkClient(void); inline boost::shared_ptr<const NetworkClient> getSharedPtr() const { return shared_from_this(); }; boost::signal <void (NetworkClientEvent&)> networkClientEventSignal; void onAsyncReadHeader(const boost::system::error_code& error, size_t bytes_transferred); }; /** NetworkClient.cpp - onAsyncReadHeader method called from io_service.run() thread as result of an async_read operation. Error condition usually result of an unexpected client disconnect.**/ void NetworkClient::onAsyncReadHeader( const boost::system::error_code& error, size_t bytes_transferred) { if (error) { //Make sure this instance doesn't get deleted from parent/slot deferencing //Alternatively, somehow schedule for future delete? boost::shared_ptr<const NetworkClient> clientPtr = getSharedPtr(); //Signal to service that this client is disconnecting NetworkClientEvent evt(*this, NetworkClientEvent::CLIENT_ERROR); networkClientEventSignal(evt); networkClientEventSignal.disconnect_all_slots(); return; } I believe it's not safe to delete the client from within the slot handler because the function return would be ... undefined? (Interestingly, it doesn't seem to blow up on me though.) So I've used boost:shared_ptr along with shared_from_this to make sure the client doesn't get deleted until all slots have been signaled. It doesn't seem to really matter though. I believe this question is not specific to ASIO, but the problem manifests in a peculiar way when using ASIO. I have one thread executing io_service.run(). All ASIO read/write operations are performed asynchronously. Everything works fine with multiple clients connecting/disconnecting UNLESS I delete my client object from the Set per the code above. If I delete my client object, the io_service seemingly deadlocks internally and no further asynchronous operations are performed unless I start another thread. I have try/catches around the io_service.run() call and have not been able to detect any errors. Questions: Are there best practices for deleting child objects, that are also signal emitters, from within parent slots? Any ideas as to why the io_service is hanging when I delete my network client object?

  • Good coding style to do case-select in XSLT

    - by Scud
    I want to have a page display A,B,C,D depending on the return value from XML value (1,2,3,4). My approaches are by javascript or XSLT:choose. I want to know which way is better, and why? Can I do this case-select in .cs code (good or bad)? Should I javascript code in XSLT? Can the community please advise? Thanks. Below are the code.

  • Nested form problem in Rails : NoMethodError in Show

    - by brianheys
    I'm trying to build a simple product backlog application to teach myself Rails. For each product, there can be multiple product backlog entries, so I want to create a product view that shows the product information, all the backlog entries for the product, and includes a nested form for adding more backlog entries. Everything works until I try to add the form to the view, which then results in the following error: NoMethodError in Products#show Showing app/views/products/show.html.erb where line #29 raised: undefined method `pblog_ref' for #<Product:0x10423ba68> Extracted source (around line #29): 26: <%= f.error_messages %> 27: <p> 28: <%= f.label :pblog_ref %><br /> 29: <%= f.text_field :pblog_ref %> 30: </p> 31: <p> 32: <%= f.label :product %><br /> The product view where the problem is reported is as follows (the partial works fine, so I won't include that code): <h1>Showing product</h1> <p> <b>Product ref:</b> <%=h @product.product_ref %> </p> <p> <b>Description:</b> <%=h @product.description %> </p> <p> <b>Owner:</b> <%=h @product.owner %> </p> <p> <b>Status:</b> <%=h @product.status %> </p> <h2>Product backlog</h2> <div id="product-backlog"> <%= render :partial => @product.product_backlogs %> </div> <% form_for(@product, ProductBacklog.new) do |f| %> <%= f.error_messages %> <p> <%= f.label :pblog_ref %><br /> <%= f.text_field :pblog_ref %> </p> <p> <%= f.label :product %><br /> <%= f.text_field :product %> </p> <p> <%= f.label :description %><br /> <%= f.text_field :description %> </p> <p> <%= f.label :owner %><br /> <%= f.text_field :owner %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Edit', edit_product_path(@product) %> | <%= link_to 'Back', products_path %> This is the Product model: class Product < ActiveRecord::Base validates_presence_of :product_ref, :description, :owner has_many :product_backlogs end This is the ProductBacklog model: class ProductBacklog < ActiveRecord::Base belongs_to :product end These are the routes: map.resources :product_backlogs map.resources :products, :has_many => :product_backlogs I've checked what I'm doing against the Creating a weblog in 15 minutes with Rails 2 screencast, and in principle I seem to be doing the same thing as him - only his nested comments form works, and mine doesn't! I hope someone can help with this, before I turn mad! I'm sure it's something trivial.

  • HTML + javascript mouse over, mouseout, onclick not working in firefox.

    - by lucky
    Hello Everyone, My question is to get onMouseover,onMouseout,onMousedown,onClick on a table row. For which i am calling javascript userdefined functions. onMouseover --- Background color should change. onMouseout --- Reset to original color onClick --- First column checkbox/radio button should be set and background color should change onMousedown --- background color should change. My code in html is:- <tr onMouseOver="hover(this)" onMouseOut="hover_out(this)" onMouseDown="get_first_state(this)" onClick="checkit(this)" > and the methods in javascripts are:- var first_state = false; var oldcol = '#ffffff'; var oldcol_cellarray = new Array(); function hover(element) { if (! element) element = this; while (element.tagName != 'TR') { element = element.parentNode; } if (element.style.fontWeight != 'bold') { for (var i = 0; i<element.cells.length; i++) { if (element.cells[i].className != "no_hover") { oldcol_cellarray[i] = element.cells[i].style.backgroundColor; element.cells[i].style.backgroundColor='#e6f6f6'; } } } } // ----------------------------------------------------------------------------------------------- function hover_out(element) { if (! element) element = this; while (element.tagName != 'TR') { element = element.parentNode; } if (element.style.fontWeight != 'bold') { for (var i = 0; i<element.cells.length; i++) { if (element.cells[i].className != "no_hover") { if (typeof oldcol_cellarray != undefined) { element.cells[i].style.backgroundColor=oldcol_cellarray[i]; } else { element.cells[i].style.backgroundColor='#ffffff'; } //var oldcol_cellarray = new Array(); } } } } // ----------------------------------------------------------------------------------------------- function get_first_state(element) { while (element.tagName != 'TR') { element = element.parentNode; } first_state = element.cells[0].firstChild.checked; } // ----------------------------------------------------------------------------------------------- function checkit (element) { while (element.tagName != 'TR') { element = element.parentNode; } if (element.cells[0].firstChild.type == 'radio') { var typ = 0; } else if (element.cells[0].firstChild.type == 'checkbox') { typ = 1; } if (element.cells[0].firstChild.checked == true && typ == 1) { if (element.cells[0].firstChild.checked == first_state) { element.cells[0].firstChild.checked = false; } set_rowstyle(element, element.cells[0].firstChild.checked); } else { if (typ == 0 || element.cells[0].firstChild.checked == first_state) { element.cells[0].firstChild.checked = true; } set_rowstyle(element, element.cells[0].firstChild.checked); } if (typ == 0) { var table = element.parentNode; if (table.tagName != "TABLE") { table = table.parentNode; } if (table.tagName == "TABLE") { table=table.tBodies[0].rows; //var table = document.getElementById("js_tb").tBodies[0].rows; for (var i = 1; i< table.length; i++) { if (table[i].cells[0].firstChild.checked == true && table[i] != element) { table[i].cells[0].firstChild.checked = false; } if (table[i].cells[0].firstChild.checked == false) { set_rowstyle(table[i], false); } } } } } function set_rowstyle(r, on) { if (on == true) { for (var i =0; i < r.cells.length; i++) { r.style.fontWeight = 'bold'; r.cells[i].style.backgroundColor = '#f2f2c2'; } } else { for ( i =0; i < r.cells.length; i++) { r.style.fontWeight = 'normal'; r.cells[i].style.backgroundColor = '#ffffff'; } } } It is working as expected in IE. But coming to firefox i am surprised on seeing the output after so much of coding. In Firefox:-- onMouseOver is working as expected. color change of that particular row. onClick -- Setting the background color permenantly..eventhough i do onmouseover on different rows. the clicked previous row color is not reset to white. -- not as expected onclick on 2 rows..the background of both the rows is set..Only the latest row color should be set. other rows that are selected before should be set back..not as expected i.e if i click on all the rows..background color of everything is changed... Eventhough i click on the row. First column i.e radio button or checkbox is not set.. Please help me to solve this issue in firefox. Do let me know where my code needs to be changed... Thanks in advance!!

  • Rails: Problem with routes and special Action.

    - by Newbie
    Hello! Sorry for this question but I can't find my error! In my Project I have my model called "team". A User can create a "team" or a "contest". The difference between this both is, that contest requires more data than a normal team. So I created the columns in my team table. Well... I also created a new view called create_contest.html.erb : <h1>New team content</h1> <% form_for @team, :url => { :action => 'create_content' } do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p> <%= f.label :url %><br /> <%= f.text_fiels :url %> </p> <p> <%= f.label :contact_name %><br /> <%= f.text_fiels :contact_name %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> In my teams_controller, I created following functions: def new_contest end def create_contest if @can_create @team = Team.new(params[:team]) @team.user_id = current_user.id respond_to do |format| if @team.save format.html { redirect_to(@team, :notice => 'Contest was successfully created.') } format.xml { render :xml => @team, :status => :created, :location => @team } else format.html { render :action => "new" } format.xml { render :xml => @team.errors, :status => :unprocessable_entity } end end else redirect_back_or_default('/') end end Now, I want on my teams/new.html.erb a link to "new_contest.html.erb". So I did: <%= link_to 'click here for new contest!', new_contest_team_path %> When I go to the /teams/new.html.erb page, I get following error: undefined local variable or method `new_contest_team_path' for #<ActionView::Base:0x16fc4f7> So I changed in my routes.rb, map.resources :teams to map.resources :teams, :member=>{:new_contest => :get} Now I get following error: new_contest_team_url failed to generate from {:controller=>"teams", :action=>"new_contest"} - you may have ambiguous routes, or you may need to supply additional parameters for this route. content_url has the following required parameters: ["teams", :id, "new_contest"] - are they all satisfied? I don't think adding :member => {...} is the right way doing this. So, can you tell me what to do? I want to have an URL like /teams/new-contest or something. My next question: what to do (after fixing the first problem), to validate presentence of all fields for new_contest.html.erb? In my normal new.html.erb, a user does not need all the data. But in new_contest.html.erb he does. Is there a way to make a validates_presence_of only for one action (in this case new_contest)? UPDATE: Now, I removed my :member part from my routes.rb and wrote: map.new_contest '/teams/contest/new', :controller => 'teams', :action => 'new_contest' Now, clicking on my link, it redirects me to /teams/contest/new - like I wanted - but I get another error called: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id I think this error is cause of @team at <% form_for @team, :url => { :action => 'create_content_team' } do |f| %> What to do for solving this error?

  • Yet Another ASP.NET MVC CRUD Tutorial

    - by Ricardo Peres
    I know that I have not posted much on MVC, mostly because I don’t use it on my daily life, but since I find it so interesting, and since it is gaining such popularity, I will be talking about it much more. This time, it’s about the most basic of scenarios: CRUD. Although there are several ASP.NET MVC tutorials out there that cover ordinary CRUD operations, I couldn’t find any that would explain how we can have also AJAX, optimistic concurrency control and validation, using Entity Framework Code First, so I set out to write one! I won’t go into explaining what is MVC, Code First or optimistic concurrency control, or AJAX, I assume you are all familiar with these concepts by now. Let’s consider an hypothetical use case, products. For simplicity, we only want to be able to either view a single product or edit this product. First, we need our model: 1: public class Product 2: { 3: public Product() 4: { 5: this.Details = new HashSet<OrderDetail>(); 6: } 7:  8: [Required] 9: [StringLength(50)] 10: public String Name 11: { 12: get; 13: set; 14: } 15:  16: [Key] 17: [ScaffoldColumn(false)] 18: [DatabaseGenerated(DatabaseGeneratedOption.Identity)] 19: public Int32 ProductId 20: { 21: get; 22: set; 23: } 24:  25: [Required] 26: [Range(1, 100)] 27: public Decimal Price 28: { 29: get; 30: set; 31: } 32:  33: public virtual ISet<OrderDetail> Details 34: { 35: get; 36: protected set; 37: } 38:  39: [Timestamp] 40: [ScaffoldColumn(false)] 41: public Byte[] RowVersion 42: { 43: get; 44: set; 45: } 46: } Keep in mind that this is a simple scenario. Let’s see what we have: A class Product, that maps to a product record on the database; A product has a required (RequiredAttribute) Name property which can contain up to 50 characters (StringLengthAttribute); The product’s Price must be a decimal value between 1 and 100 (RangeAttribute); It contains a set of order details, for each time that it has been ordered, which we will not talk about (Details); The record’s primary key (mapped to property ProductId) comes from a SQL Server IDENTITY column generated by the database (KeyAttribute, DatabaseGeneratedAttribute); The table uses a SQL Server ROWVERSION (previously known as TIMESTAMP) column for optimistic concurrency control mapped to property RowVersion (TimestampAttribute). Then we will need a controller for viewing product details, which will located on folder ~/Controllers under the name ProductController: 1: public class ProductController : Controller 2: { 3: [HttpGet] 4: public ViewResult Get(Int32 id = 0) 5: { 6: if (id != 0) 7: { 8: using (ProductContext ctx = new ProductContext()) 9: { 10: return (this.View("Single", ctx.Products.Find(id) ?? new Product())); 11: } 12: } 13: else 14: { 15: return (this.View("Single", new Product())); 16: } 17: } 18: } If the requested product does not exist, or one was not requested at all, one with default values will be returned. I am using a view named Single to display the product’s details, more on that later. As you can see, it delegates the loading of products to an Entity Framework context, which is defined as: 1: public class ProductContext: DbContext 2: { 3: public DbSet<Product> Products 4: { 5: get; 6: set; 7: } 8: } Like I said before, I’ll keep it simple for now, only aggregate root Product is available. The controller will use the standard routes defined by the Visual Studio ASP.NET MVC 3 template: 1: routes.MapRoute( 2: "Default", // Route name 3: "{controller}/{action}/{id}", // URL with parameters 4: new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults 5: ); Next, we need a view for displaying the product details, let’s call it Single, and have it located under ~/Views/Product: 1: <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<Product>" %> 2: <!DOCTYPE html> 3:  4: <html> 5: <head runat="server"> 6: <title>Product</title> 7: <script src="/Scripts/jquery-1.7.2.js" type="text/javascript"></script> 1:  2: <script src="/Scripts/jquery-ui-1.8.19.js" type="text/javascript"> 1: </script> 2: <script src="/Scripts/jquery.unobtrusive-ajax.js" type="text/javascript"> 1: </script> 2: <script src="/Scripts/jquery.validate.js" type="text/javascript"> 1: </script> 2: <script src="/Scripts/jquery.validate.unobtrusive.js" type="text/javascript"> 1: </script> 2: <script type="text/javascript"> 3: function onFailure(error) 4: { 5: } 6:  7: function onComplete(ctx) 8: { 9: } 10:  11: </script> 8: </head> 9: <body> 10: <div> 11: <% 1: : this.Html.ValidationSummary(false) %> 12: <% 1: using (this.Ajax.BeginForm("Edit", "Product", new AjaxOptions{ HttpMethod = FormMethod.Post.ToString(), OnSuccess = "onSuccess", OnFailure = "onFailure" })) { %> 13: <% 1: : this.Html.EditorForModel() %> 14: <input type="submit" name="submit" value="Submit" /> 15: <% 1: } %> 16: </div> 17: </body> 18: </html> Yes… I am using ASPX syntax… sorry about that!   I implemented an editor template for the Product class, which must be located on the ~/Views/Shared/EditorTemplates folder as file Product.ascx: 1: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Product>" %> 2: <div> 3: <%: this.Html.HiddenFor(model => model.ProductId) %> 4: <%: this.Html.HiddenFor(model => model.RowVersion) %> 5: <fieldset> 6: <legend>Product</legend> 7: <div class="editor-label"> 8: <%: this.Html.LabelFor(model => model.Name) %> 9: </div> 10: <div class="editor-field"> 11: <%: this.Html.TextBoxFor(model => model.Name) %> 12: <%: this.Html.ValidationMessageFor(model => model.Name) %> 13: </div> 14: <div class="editor-label"> 15: <%= this.Html.LabelFor(model => model.Price) %> 16: </div> 17: <div class="editor-field"> 18: <%= this.Html.TextBoxFor(model => model.Price) %> 19: <%: this.Html.ValidationMessageFor(model => model.Price) %> 20: </div> 21: </fieldset> 22: </div> One thing you’ll notice is, I am including both the ProductId and the RowVersion properties as hidden fields; they will come handy later or, so that we know what product and version we are editing. The other thing is the included JavaScript files: jQuery, jQuery UI and unobtrusive validations. Also, I am not using the Content extension method for translating relative URLs, because that way I would lose JavaScript intellisense for jQuery functions. OK, so, at this moment, I want to add support for AJAX and optimistic concurrency control. So I write a controller method like this: 1: [HttpPost] 2: [AjaxOnly] 3: [Authorize] 4: public JsonResult Edit(Product product) 5: { 6: if (this.TryValidateModel(product) == true) 7: { 8: using (BlogContext ctx = new BlogContext()) 9: { 10: Boolean success = false; 11:  12: ctx.Entry(product).State = (product.ProductId == 0) ? EntityState.Added : EntityState.Modified; 13:  14: try 15: { 16: success = (ctx.SaveChanges() == 1); 17: } 18: catch (DbUpdateConcurrencyException) 19: { 20: ctx.Entry(product).Reload(); 21: } 22:  23: return (this.Json(new { Success = success, ProductId = product.ProductId, RowVersion = Convert.ToBase64String(product.RowVersion) })); 24: } 25: } 26: else 27: { 28: return (this.Json(new { Success = false, ProductId = 0, RowVersion = String.Empty })); 29: } 30: } So, this method is only valid for HTTP POST requests (HttpPost), coming from AJAX (AjaxOnly, from MVC Futures), and from authenticated users (Authorize). It returns a JSON object, which is what you would normally use for AJAX requests, containing three properties: Success: a boolean flag; RowVersion: the current version of the ROWVERSION column as a Base-64 string; ProductId: the inserted product id, as coming from the database. If the product is new, it will be inserted into the database, and its primary key will be returned into the ProductId property. Success will be set to true; If a DbUpdateConcurrencyException occurs, it means that the value in the RowVersion property does not match the current ROWVERSION column value on the database, so the record must have been modified between the time that the page was loaded and the time we attempted to save the product. In this case, the controller just gets the new value from the database and returns it in the JSON object; Success will be false. Otherwise, it will be updated, and Success, ProductId and RowVersion will all have their values set accordingly. So let’s see how we can react to these situations on the client side. Specifically, we want to deal with these situations: The user is not logged in when the update/create request is made, perhaps the cookie expired; The optimistic concurrency check failed; All went well. So, let’s change our view: 1: <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<Product>" %> 2: <%@ Import Namespace="System.Web.Security" %> 3:  4: <!DOCTYPE html> 5:  6: <html> 7: <head runat="server"> 8: <title>Product</title> 9: <script src="/Scripts/jquery-1.7.2.js" type="text/javascript"></script> 1:  2: <script src="/Scripts/jquery-ui-1.8.19.js" type="text/javascript"> 1: </script> 2: <script src="/Scripts/jquery.unobtrusive-ajax.js" type="text/javascript"> 1: </script> 2: <script src="/Scripts/jquery.validate.js" type="text/javascript"> 1: </script> 2: <script src="/Scripts/jquery.validate.unobtrusive.js" type="text/javascript"> 1: </script> 2: <script type="text/javascript"> 3: function onFailure(error) 4: { 5: window.alert('An error occurred: ' + error); 6: } 7:  8: function onSuccess(ctx) 9: { 10: if (typeof (ctx.Success) != 'undefined') 11: { 12: $('input#ProductId').val(ctx.ProductId); 13: $('input#RowVersion').val(ctx.RowVersion); 14:  15: if (ctx.Success == false) 16: { 17: window.alert('An error occurred while updating the entity: it may have been modified by third parties. Please try again.'); 18: } 19: else 20: { 21: window.alert('Saved successfully'); 22: } 23: } 24: else 25: { 26: if (window.confirm('Not logged in. Login now?') == true) 27: { 28: document.location.href = '<%: FormsAuthentication.LoginUrl %>?ReturnURL=' + document.location.pathname; 29: } 30: } 31: } 32:  33: </script> 10: </head> 11: <body> 12: <div> 13: <% 1: : this.Html.ValidationSummary(false) %> 14: <% 1: using (this.Ajax.BeginForm("Edit", "Product", new AjaxOptions{ HttpMethod = FormMethod.Post.ToString(), OnSuccess = "onSuccess", OnFailure = "onFailure" })) { %> 15: <% 1: : this.Html.EditorForModel() %> 16: <input type="submit" name="submit" value="Submit" /> 17: <% 1: } %> 18: </div> 19: </body> 20: </html> The implementation of the onSuccess function first checks if the response contains a Success property, if not, the most likely cause is the request was redirected to the login page (using Forms Authentication), because it wasn’t authenticated, so we navigate there as well, keeping the reference to the current page. It then saves the current values of the ProductId and RowVersion properties to their respective hidden fields. They will be sent on each successive post and will be used in determining if the request is for adding a new product or to updating an existing one. The only thing missing is the ability to insert a new product, after inserting/editing an existing one, which can be easily achieved using this snippet: 1: <input type="button" value="New" onclick="$('input#ProductId').val('');$('input#RowVersion').val('');"/> And that’s it.

  • Nagging As A Strategy For Better Linking: -z guidance

    - by user9154181
    The link-editor (ld) in Solaris 11 has a new feature that we call guidance that is intended to help you build better objects. The basic idea behind guidance is that if (and only if) you request it, the link-editor will issue messages suggesting better options and other changes you might make to your ld command to get better results. You can choose to take the advice, or you can disable specific types of guidance while acting on others. In some ways, this works like an experienced friend leaning over your shoulder and giving you advice — you're free to take it or leave it as you see fit, but you get nudged to do a better job than you might have otherwise. We use guidance to build the core Solaris OS, and it has proven to be useful, both in improving our objects, and in making sure that regressions don't creep back in later. In this article, I'm going to describe the evolution in thinking and design that led to the implementation of the -z guidance option, as well as give a brief description of how it works. The guidance feature issues non-fatal warnings. However, experience shows that once developers get used to ignoring warnings, it is inevitable that real problems will be lost in the noise and ignored or missed. This is why we have a zero tolerance policy against build noise in the core Solaris OS. In order to get maximum benefit from -z guidance while maintaining this policy, I added the -z fatal-warnings option at the same time. Much of the material presented here is adapted from the arc case: PSARC 2010/312 Link-editor guidance The History Of Unfortunate Link-Editor Defaults The Solaris link-editor is one of the oldest Unix commands. It stands to reason that this would be true — in order to write an operating system, you need the ability to compile and link code. The original link-editor (ld) had defaults that made sense at the time. As new features were needed, command line option switches were added to let the user use them, while maintaining backward compatibility for those who didn't. Backward compatibility is always a concern in system design, but is particularly important in the case of the tool chain (compilers, linker, and related tools), since it is a basic building block for the entire system. Over the years, applications have grown in size and complexity. Important concepts like dynamic linking that didn't exist in the original Unix system were invented. Object file formats changed. In the case of System V Release 4 Unix derivatives like Solaris, the ELF (Extensible Linking Format) was adopted. Since then, the ELF system has evolved to provide tools needed to manage today's larger and more complex environments. Features such as lazy loading, and direct bindings have been added. In an ideal world, many of these options would be defaults, with rarely used options that allow the user to turn them off. However, the reality is exactly the reverse: For backward compatibility, these features are all options that must be explicitly turned on by the user. This has led to a situation in which most applications do not take advantage of the many improvements that have been made in linking over the last 20 years. If their code seems to link and run without issue, what motivation does a developer have to read a complex manpage, absorb the information provided, choose the features that matter for their application, and apply them? Experience shows that only the most motivated and diligent programmers will make that effort. We know that most programs would be improved if we could just get you to use the various whizzy features that we provide, but the defaults conspire against us. We have long wanted to do something to make it easier for our users to use the linkers more effectively. There have been many conversations over the years regarding this issue, and how to address it. They always break down along the following lines: Change ld Defaults Since the world would be a better place the newer ld features were the defaults, why not change things to make it so? This idea is simple, elegant, and impossible. Doing so would break a large number of existing applications, including those of ISVs, big customers, and a plethora of existing open source packages. In each case, the owner of that code may choose to follow our lead and fix their code, or they may view it as an invitation to reconsider their commitment to our platform. Backward compatibility, and our installed base of working software, is one of our greatest assets, and not something to be lightly put at risk. Breaking backward compatibility at this level of the system is likely to do more harm than good. But, it sure is tempting. New Link-Editor One might create a new linker command, not called 'ld', leaving the old command as it is. The new one could use the same code as ld, but would offer only modern options, with the proper defaults for features such as direct binding. The resulting link-editor would be a pleasure to use. However, the approach is doomed to niche status. There is a vast pile of exiting code in the world built around the existing ld command, that reaches back to the 1970's. ld use is embedded in large and unknown numbers of makefiles, and is used by name by compilers that execute it. A Unix link-editor that is not named ld will not find a majority audience no matter how good it might be. Finally, a new linker command will eventually cease to be new, and will accumulate its own burden of backward compatibility issues. An Option To Make ld Do The Right Things Automatically This line of reasoning is best summarized by a CR filed in 2005, entitled 6239804 make it easier for ld(1) to do what's best The idea is to have a '-z best' option that unchains ld from its backward compatibility commitment, and allows it to turn on the "best" set of features, as determined by the authors of ld. The specific set of features enabled by -z best would be subject to change over time, as requirements change. This idea is more realistic than the other two, but was never implemented because it has some important issues that we could never answer to our satisfaction: The -z best proposal assumes that the user can turn it on, and trust it to select good options without the user needing to be aware of the options being applied. This is a fallacy. Features such as direct bindings require the user to do some analysis to ensure that the resulting program will still operate properly. A user who is willing to do the work to verify that what -z best does will be OK for their application is capable of turning on those features directly, and therefore gains little added benefit from -z best. The intent is that when a user opts into -z best, that they understand that z best is subject to sometimes incompatible evolution. Experience teaches us that this won't work. People will use this feature, the meaning of -z best will change, code that used to build will fail, and then there will be complaints and demands to retract the change. When (not if) this occurs, we will of course defend our actions, and point at the disclaimer. We'll win some of those debates, and lose others. Ultimately, we'll end up with -z best2 (-z better), or other compromises, and our goal of simplifying the world will have failed. The -z best idea rolls up a set of features that may or may not be related to each other into a unit that must be taken wholesale, or not at all. It could be that only a subset of what it does is compatible with a given application, in which case the user is expected to abandon -z best and instead set the options that apply to their application directly. In doing so, they lose one of the benefits of -z best, that if you use it, future versions of ld may choose a different set of options, and automatically improve the object through the act of rebuilding it. I drew two conclusions from the above history: For a link-editor, backward compatibility is vital. If a given command line linked your application 10 years ago, you have every reason to expect that it will link today, assuming that the libraries you're linking against are still available and compatible with their previous interfaces. For an application of any size or complexity, there is no substitute for the work involved in examining the code and determining which linker options apply and which do not. These options are largely orthogonal to each other, and it can be reasonable not to use any or all of them, depending on the situation, even in modern applications. It is a mistake to tie them together. The idea for -z guidance came from consideration of these points. By decoupling the advice from the act of taking the advice, we can retain the good aspects of -z best while avoiding its pitfalls: -z guidance gives advice, but the decision to take that advice remains with the user who must evaluate its merit and make a decision to take it or not. As such, we are free to change the specific guidance given in future releases of ld, without breaking existing applications. The only fallout from this will be some new warnings in the build output, which can be ignored or dealt with at the user's convenience. It does not couple the various features given into a single "take it or leave it" option, meaning that there will never be a need to offer "-zguidance2", or other such variants as things change over time. Guidance has the potential to be our final word on this subject. The user is given the flexibility to disable specific categories of guidance without losing the benefit of others, including those that might be added to future versions of the system. Although -z fatal-warnings stands on its own as a useful feature, it is of particular interest in combination with -z guidance. Used together, the guidance turns from advice to hard requirement: The user must either make the suggested change, or explicitly reject the advice by specifying a guidance exception token, in order to get a build. This is valuable in environments with high coding standards. ld Command Line Options The guidance effort resulted in new link-editor options for guidance and for turning warnings into fatal errors. Before I reproduce that text here, I'd like to highlight the strategic decisions embedded in the guidance feature: In order to get guidance, you have to opt in. We hope you will opt in, and believe you'll get better objects if you do, but our default mode of operation will continue as it always has, with full backward compatibility, and without judgement. Guidance suggestions always offers specific advice, and not vague generalizations. You can disable some guidance without turning off the entire feature. When you get guidance warnings, you can choose to take the advice, or you can specify a keyword to disable guidance for just that category. This allows you to get guidance for things that are useful to you, without being bothered about things that you've already considered and dismissed. As the world changes, we will add new guidance to steer you in the right direction. All such new guidance will come with a keyword that let's you turn it off. In order to facilitate building your code on different versions of Solaris, we quietly ignore any guidance keywords we don't recognize, assuming that they are intended for newer versions of the link-editor. If you want to see what guidance tokens ld does and does not recognize on your system, you can use the ld debugging feature as follows: % ld -Dargs -z guidance=foo,nodefs debug: debug: Solaris Linkers: 5.11-1.2275 debug: debug: arg[1] option=-D: option-argument: args debug: arg[2] option=-z: option-argument: guidance=foo,nodefs debug: warning: unrecognized -z guidance item: foo The -z fatal-warning option is straightforward, and generally useful in environments with strict coding standards. Note that the GNU ld already had this feature, and we accept their option names as synonyms: -z fatal-warnings | nofatal-warnings --fatal-warnings | --no-fatal-warnings The -z fatal-warnings and the --fatal-warnings option cause the link-editor to treat warnings as fatal errors. The -z nofatal-warnings and the --no-fatal-warnings option cause the link-editor to treat warnings as non-fatal. This is the default behavior. The -z guidance option is defined as follows: -z guidance[=item1,item2,...] Provide guidance messages to suggest ld options that can improve the quality of the resulting object, or which are otherwise considered to be beneficial. The specific guidance offered is subject to change over time as the system evolves. Obsolete guidance offered by older versions of ld may be dropped in new versions. Similarly, new guidance may be added to new versions of ld. Guidance therefore always represents current best practices. It is possible to enable guidance, while preventing specific guidance messages, by providing a list of item tokens, representing the class of guidance to be suppressed. In this way, unwanted advice can be suppressed without losing the benefit of other guidance. Unrecognized item tokens are quietly ignored by ld, allowing a given ld command line to be executed on a variety of older or newer versions of Solaris. The guidance offered by the current version of ld, and the item tokens used to disable these messages, are as follows. Specify Required Dependencies Dynamic executables and shared objects should explicitly define all of the dependencies they require. Guidance recommends the use of the -z defs option, should any symbol references remain unsatisfied when building dynamic objects. This guidance can be disabled with -z guidance=nodefs. Do Not Specify Non-Required Dependencies Dynamic executables and shared objects should not define any dependencies that do not satisfy the symbol references made by the dynamic object. Guidance recommends that unused dependencies be removed. This guidance can be disabled with -z guidance=nounused. Lazy Loading Dependencies should be identified for lazy loading. Guidance recommends the use of the -z lazyload option should any dependency be processed before either a -z lazyload or -z nolazyload option is encountered. This guidance can be disabled with -z guidance=nolazyload. Direct Bindings Dependencies should be referenced with direct bindings. Guidance recommends the use of the -B direct, or -z direct options should any dependency be processed before either of these options, or the -z nodirect option is encountered. This guidance can be disabled with -z guidance=nodirect. Pure Text Segment Dynamic objects should not contain relocations to non-writable, allocable sections. Guidance recommends compiling objects with Position Independent Code (PIC) should any relocations against the text segment remain, and neither the -z textwarn or -z textoff options are encountered. This guidance can be disabled with -z guidance=notext. Mapfile Syntax All mapfiles should use the version 2 mapfile syntax. Guidance recommends the use of the version 2 syntax should any mapfiles be encountered that use the version 1 syntax. This guidance can be disabled with -z guidance=nomapfile. Library Search Path Inappropriate dependencies that are encountered by ld are quietly ignored. For example, a 32-bit dependency that is encountered when generating a 64-bit object is ignored. These dependencies can result from incorrect search path settings, such as supplying an incorrect -L option. Although benign, this dependency processing is wasteful, and might hide a build problem that should be solved. Guidance recommends the removal of any inappropriate dependencies. This guidance can be disabled with -z guidance=nolibpath. In addition, -z guidance=noall can be used to entirely disable the guidance feature. See Chapter 7, Link-Editor Quick Reference, in the Linker and Libraries Guide for more information on guidance and advice for building better objects. Example The following example demonstrates how the guidance feature is intended to work. We will build a shared object that has a variety of shortcomings: Does not specify all it's dependencies Specifies dependencies it does not use Does not use direct bindings Uses a version 1 mapfile Contains relocations to the readonly allocable text (not PIC) This scenario is sadly very common — many shared objects have one or more of these issues. % cat hello.c #include <stdio.h> #include <unistd.h> void hello(void) { printf("hello user %d\n", getpid()); } % cat mapfile.v1 # This version 1 mapfile will trigger a guidance message % cc hello.c -o hello.so -G -M mapfile.v1 -lelf As you can see, the operation completes without error, resulting in a usable object. However, turning on guidance reveals a number of things that could be better: % cc hello.c -o hello.so -G -M mapfile.v1 -lelf -zguidance ld: guidance: version 2 mapfile syntax recommended: mapfile.v1 ld: guidance: -z lazyload option recommended before first dependency ld: guidance: -B direct or -z direct option recommended before first dependency Undefined first referenced symbol in file getpid hello.o (symbol belongs to implicit dependency /lib/libc.so.1) printf hello.o (symbol belongs to implicit dependency /lib/libc.so.1) ld: warning: symbol referencing errors ld: guidance: -z defs option recommended for shared objects ld: guidance: removal of unused dependency recommended: libelf.so.1 warning: Text relocation remains referenced against symbol offset in file .rodata1 (section) 0xa hello.o getpid 0x4 hello.o printf 0xf hello.o ld: guidance: position independent (PIC) code recommended for shared objects ld: guidance: see ld(1) -z guidance for more information Given the explicit advice in the above guidance messages, it is relatively easy to modify the example to do the right things: % cat mapfile.v2 # This version 2 mapfile will not trigger a guidance message $mapfile_version 2 % cc hello.c -o hello.so -Kpic -G -Bdirect -M mapfile.v2 -lc -zguidance There are situations in which the guidance does not fit the object being built. For instance, you want to build an object without direct bindings: % cc -Kpic hello.c -o hello.so -G -M mapfile.v2 -lc -zguidance ld: guidance: -B direct or -z direct option recommended before first dependency ld: guidance: see ld(1) -z guidance for more information It is easy to disable that specific guidance warning without losing the overall benefit from allowing the remainder of the guidance feature to operate: % cc -Kpic hello.c -o hello.so -G -M mapfile.v2 -lc -zguidance=nodirect Conclusions The linking guidelines enforced by the ld guidance feature correspond rather directly to our standards for building the core Solaris OS. I'm sure that comes as no surprise. It only makes sense that we would want to build our own product as well as we know how. Solaris is usually the first significant test for any new linker feature. We now enable guidance by default for all builds, and the effect has been very positive. Guidance helps us find suboptimal objects more quickly. Programmers get concrete advice for what to change instead of vague generalities. Even in the cases where we override the guidance, the makefile rules to do so serve as documentation of the fact. Deciding to use guidance is likely to cause some up front work for most code, as it forces you to consider using new features such as direct bindings. Such investigation is worthwhile, but does not come for free. However, the guidance suggestions offer a structured and straightforward way to tackle modernizing your objects, and once that work is done, for keeping them that way. The investment is often worth it, and will replay you in terms of better performance and fewer problems. I hope that you find guidance to be as useful as we have.

  • Ruby on Rails: url_for :back leads to NoMethodError for back_url

    - by Platinum Azure
    Hi all, I'm trying to use url_for(:back) to create a redirect leading back to a previous page upon a user's logging in. I've had it working successfully for when the user just goes to the login page on his or her own. However, when the user is redirected to the login page due to accessing a page requiring that the user be authenticated, the redirect sends the user back to the page before the one s/he had tried to access with insufficient permissions. I'm trying to modify my login controller action to deal with the redirect properly. My plan is to have a query string parameter "redirect" that is used when a forced redirect occurs. In the controller, if that parameter exists that URL is used; otherwise, url_for(:back) is used, or if that doesn't work (due to lack of HTTP_REFERER), then the user is redirected to the site's home page. Here is the code snippet which is supposed to implement this logic: if params[:redirect] @url = params[:redirect] else @url = url_for :back @url ||= url_for :controller => "home", :action => "index" end The error I get is: NoMethodError in UsersController#login undefined method `back_url' for # RAILS_ROOT: [obscured] Application Trace | Framework Trace | Full Trace

  • Asset Pipeline acting up

    - by Abram
    Ok, so my asset pipeline has suddenly started acting up on my development machine. JS functions that previously worked are now throwing "not a function" errors.. I know I must be doing something wrong. A minute ago the datatables jquery function was working, then it was throwing an error, then it was working, and now it's not working or throwing an error. Here is my application.js //= require jquery //= require jquery-ui //= require jquery_ujs //= require_self //= require_tree . //= require dataTables/jquery.dataTables //= require dataTables/jquery.dataTables.bootstrap //= require bootstrap //= require bootstrap-tooltip //= require bootstrap-popover //= require bootstrap-tab //= require bootstrap-modal //= require bootstrap-alert //= require bootstrap-dropdown //= require jquery.ui.addresspicker //= require raty //= require jquery.alphanumeric //= require jquery.formrestrict //= require select2 //= require chosen/chosen.jquery //= require highcharts //= require jquery.lazyload Here is some of my layout header: <%= stylesheet_link_tag "application", media: "all" %> <%= yield(:scripthead) %> <%= javascript_include_tag "application" %> <%= csrf_meta_tags %> <%= yield(:head) %> Above I am using the yield to load up online scripts from google as they're only needed on some pages, and generally slow down the site if included in the application layout. I tried removing the yield but things were still broken, even after clearing the browser cache and running rake assets:clean (just to be on the safe side). Here's what shows up between CSS and metatags (for a page with nothin in the yield scripthead): <script src="/assets/jquery.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui.js?body=1" type="text/javascript"></script> <script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script> <script src="/assets/application.js?body=1" type="text/javascript"></script> <script src="/assets/aidmodels.js?body=1" type="text/javascript"></script> <script src="/assets/audio.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-alert.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-dropdown.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-modal.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-popover.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tab.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tooltip.js?body=1" type="text/javascript"></script> <script src="/assets/branches.js?body=1" type="text/javascript"></script> <script src="/assets/charts.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/backup_chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/consumers.js?body=1" type="text/javascript"></script> <script src="/assets/dispensers.js?body=1" type="text/javascript"></script> <script src="/assets/favorites.js?body=1" type="text/javascript"></script> <script src="/assets/features.js?body=1" type="text/javascript"></script> <script src="/assets/generic_styles.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.base.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.bing.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.googlemaps.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.mapquest.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.openlayers.js?body=1" type="text/javascript"></script> <script src="/assets/highcharts.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui-1.8.18.custom.min.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.alphanumeric.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.formrestrict.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.lazyload.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.ui.addresspicker.js?body=1" type="text/javascript"></script> <script src="/assets/likes.js?body=1" type="text/javascript"></script> <script src="/assets/messages.js?body=1" type="text/javascript"></script> <script src="/assets/overalls.js?body=1" type="text/javascript"></script> <script src="/assets/pages.js?body=1" type="text/javascript"></script> <script src="/assets/questions.js?body=1" type="text/javascript"></script> <script src="/assets/raty.js?body=1" type="text/javascript"></script> <script src="/assets/reviews.js?body=1" type="text/javascript"></script> <script src="/assets/sessions.js?body=1" type="text/javascript"></script> <script src="/assets/styles.js?body=1" type="text/javascript"></script> <script src="/assets/tickets.js?body=1" type="text/javascript"></script> <script src="/assets/universities.js?body=1" type="text/javascript"></script> <script src="/assets/users.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-transition.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-affix.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-button.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-carousel.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-collapse.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-scrollspy.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-typeahead.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/select2.js?body=1" type="text/javascript"></script> From application.rb: config.assets.initialize_on_precompile = false # Enable the asset pipeline config.assets.enabled = true config.action_controller.assets_dir = "#{File.dirname(File.dirname(__FILE__))}/public" # Version of your assets, change this if you want to expire all your assets config.assets.version = '1.0' I'm sorry, I'm not sure what else to include to help with this puzzle, but any advise would be appreciated.

  • Passing XML markers to Google Map

    - by djmadscribbler
    I've been creating a V3 Google map based on this example from Mike Williams http://www.geocodezip.com/v3_MW_example_map3.html I've run into a bit of a problem though. If I have no parameters in my URL then I get the error "id is undefined idmarkers [id.toLowerCase()] = marker;" in Firebug and only one marker will show up. If I have a parameter (?id=105 for example) then all the sidebar links say 105 (or whatever the parameter in the URL was) instead of their respective label as listed in the XML file and a random infowindow will be opened instead of the window for the id in the URL. Here is my javascript: var map = null; var lastmarker = null; // ========== Read paramaters that have been passed in ========== // Before we go looking for the passed parameters, set some defaults // in case there are no parameters var id;

  • How do I debug this javascript -- I don't get an error in Firebug but it's not working as expected.

    - by Angela
    I installed the plugin better-edit-in-place (http://github.com/nakajima/better-edit-in-place) but I dont' seem to be able to make it work. The plugin creates javascript, and also automatically creates a rel and class. The expected behavior is to make an edit-in-place, but it currently is not. Nothing happens when I mouse over. When I use firebug, it is rendering the value to be edited correctly: <span rel="/emails/1" id="email_1_days" class="editable">7</span> And it is showing the full javascript which should work on class editable. I didn't copy everything, just the chunks that seemed should be operationable if I have a class name in the DOM. // Editable: Better in-place-editing // http://github.com/nakajima/nakatype/wikis/better-edit-in-place-editable-js var Editable = Class.create({ initialize: function(element, options) { this.element = $(element); Object.extend(this, options); // Set default values for options this.editField = this.editField || {}; this.editField.type = this.editField.type || 'input'; this.onLoading = this.onLoading || Prototype.emptyFunction; this.onComplete = this.onComplete || Prototype.emptyFunction; this.field = this.parseField(); this.value = this.element.innerHTML; this.setupForm(); this.setupBehaviors(); }, // In order to parse the field correctly, it's necessary that the element // you want to edit in place for have an id of (model_name)_(id)_(field_name). // For example, if you want to edit the "caption" field in a "Photo" model, // your id should be something like "photo_#{@photo.id}_caption". // If you want to edit the "comment_body" field in a "MemberBlogPost" model, // it would be: "member_blog_post_#{@member_blog_post.id}_comment_body" parseField: function() { var matches = this.element.id.match(/(.*)_\d*_(.*)/); this.modelName = matches[1]; this.fieldName = matches[2]; if (this.editField.foreignKey) this.fieldName += '_id'; return this.modelName + '[' + this.fieldName + ']'; }, // Create the editing form for the editable and inserts it after the element. // If window._token is defined, then we add a hidden element that contains the // authenticity_token for the AJAX request. setupForm: function() { this.editForm = new Element('form', { 'action': this.element.readAttribute('rel'), 'style':'display:none', 'class':'in-place-editor' }); this.setupInputElement(); if (this.editField.tag != 'select') { this.saveInput = new Element('input', { type:'submit', value: Editable.options.saveText }); if (this.submitButtonClass) this.saveInput.addClassName(this.submitButtonClass); this.cancelLink = new Element('a', { href:'#' }).update(Editable.options.cancelText); if (this.cancelButtonClass) this.cancelLink.addClassName(this.cancelButtonClass); } var methodInput = new Element('input', { type:'hidden', value:'put', name:'_method' }); if (typeof(window._token) != 'undefined') { this.editForm.insert(new Element('input', { type: 'hidden', value: window._token, name: 'authenticity_token' })); } this.editForm.insert(this.editField.element); if (this.editField.type != 'select') { this.editForm.insert(this.saveInput); this.editForm.insert(this.cancelLink); } this.editForm.insert(methodInput); this.element.insert({ after: this.editForm }); }, // Create input element - text input, text area or select box. setupInputElement: function() { this.editField.element = new Element(this.editField.type, { 'name':this.field, 'id':('edit_' + this.element.id) }); if(this.editField['class']) this.editField.element.addClassName(this.editField['class']); if(this.editField.type == 'select') { // Create options var options = this.editField.options.map(function(option) { return new Option(option[0], option[1]); }); // And assign them to select element options.each(function(option, index) { this.editField.element.options[index] = options[index]; }.bind(this)); // Set selected option try { this.editField.element.selectedIndex = $A(this.editField.element.options).find(function(option) { return option.text == this.element.innerHTML; }.bind(this)).index; } catch(e) { this.editField.element.selectedIndex = 0; } // Set event handlers to automaticall submit form when option is changed this.editField.element.observe('blur', this.cancel.bind(this)); this.editField.element.observe('change', this.save.bind(this)); } else { // Copy value of the element to the input this.editField.element.value = this.element.innerHTML; } }, // Sets up event handles for editable. setupBehaviors: function() { this.element.observe('click', this.edit.bindAsEventListener(this)); if (this.saveInput) this.editForm.observe('submit', this.save.bindAsEventListener(this)); if (this.cancelLink) this.cancelLink.observe('click', this.cancel.bindAsEventListener(this)); }, // Event Handler that activates form and hides element. edit: function(event) { this.element.hide(); this.editForm.show(); this.editField.element.activate ?
