  • Link redirects to "show" action instead of the indicated in routes.rb

    - by Brian Roisentul
    I'm working with Ruby on rails 2.3.4 and I'd like to have a link that executes an action when clicked. The relevant part of the routes.rb file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' My view(it's the model's index page) looks like this: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> And my controller looks like this: def search_filter_relevance raise params.inspect unless params[:announcements].nil? or params[:announcements].empty? @announcements = params[:announcements].order_by_featured end end The problem is that when I click the link I get an error due to some null value in the Show action! I'm not accessing that action at all...why is executing it?

  • Testing ActionMailer's receive method (Rails)

    - by Brian Armstrong
    There is good documentation out there on testing ActionMailer send methods which deliver mail. But I'm unable to figure out how to test a receive method that is used to parse incoming mail. I want to do something like this: require 'test_helper' class ReceiverTest < ActionMailer::TestCase test "parse incoming mail" do email = TMail::Mail.parse(File.open("test/fixtures/emails/example1.txt",'r').read) assert_difference "ProcessedMail.count" do Receiver.receive email end end end But I get the following error on the line which calls Receiver.receive NoMethodError: undefined method `index' for #<TMail::Mail:0x102c4a6f0> /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/stringio.rb:128:in `gets' /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/mail.rb:392:in `parse_header' /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/mail.rb:139:in `initialize' /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/stringio.rb:43:in `open' /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/port.rb:340:in `ropen' /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/mail.rb:138:in `initialize' /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/mail.rb:123:in `new' /Library/Ruby/Gems/1.8/gems/tmail-1.2.7.1/lib/tmail/mail.rb:123:in `parse' /Library/Ruby/Gems/1.8/gems/actionmailer-2.3.4/lib/action_mailer/base.rb:417:in `receive' Tmail is parsing the test file I have correctly. So that's not it. Thanks!

  • CREATE Excel File with hyperlinks in PHP

    - by Brian
    I have the following method to create an Excel file from in PHP starting with a two-dimensional array: header("Content-Disposition: attachment; filename=ExcelFile.xls"); header("Content-Type: application/vnd.ms-excel"); $Data[] = array('field1', 'field2', 'field3'); $Data[] = array('field1', 'field2', 'field3'); $Data[] = array('field1', 'field2', 'field3'); foreach($Data as $key => $val) { echo implode("\t", array_values($val)) . "\n"; } Would it be possible to include a hyperlink to a webpage in this file?

  • JSP Iterating over a map of a list when the value might be null

    - by Brian Hoover
    How do I clear the value from the stack of a s:iterator? I'm trying to iterator over a TreeMultimap with a structure like: TreeMultimap<person, lineItems> persons; Using something like: <s:iterator value="attendeesForParticipantTypeEvents.asMap()"> <div> <s:property value="key.name" /><br /> <s:iterator id="currentSku" value="value"> <s:property value="currentSku.name" /><br /> </s:iterator> </div> </s:iterator> This works fine, except when the treeMultimap has null for lineItems, then it's taking the value from the previous iteration. So, a structure like: persons = {{"Person1",["Line1","line2"]}, {"Person2",["Line3","line4"]}, {"Person2",null}} Renders as: <div> Person1<br /> Line1<br /> Line2<br /> </div> <div> Person2<br /> Line3<br /> Line4<br /> </div> <div> Person3<br /> Line3<br /> Line4<br /> </div> Which seems to indicate that the value isn't being cleared on each iterator. What do I need to do to handle the case where value might be null? Thanks for your help

  • How can I check for GPS support in-App to add a feature for those with Location services enabled?

    - by Brian Lacy
    How can I check for GPS support in-App to add a feature for those with Location services enabled? My concern is, I know I'd have to specify the tag in the manifest to declare that the app uses location services, but I still want the app to function for those without. I just want to check and, if the service is available, use it; otherwise just ignore that one feature. Thanks.

  • Any recommended VC++ settings for better PDB analysis on release builds

    - by Brian R. Bondy
    Are there any VC++ settings I should know about to generate better PDB files that contain more information? I have a crash dump analysis system in place based on the project crashrpt. Also, my production build server has the source code installed on the D:\, but my development machine has the source code on the C:\. I entered the source path in the VC++ settings, but when looking through the call stack of a crash, it doesn't automatically jump to my source code. I believe if I had my dev machine's source code on the D:\ it would work.

  • NHibernate will not insert a record

    - by Brian Beckham
    I have an application that is now 4+ years old that is exhibiting some odd behavior on our latest deployment. The application uses nHibernate for all inserts / updates / selects, etc. We are currently using .NET 2.0, and nHibernate 1.2 (I know, we need to upgrade) This deployment is on Windows 2008 Server x64, IIS 7.5 - what I have seen so far is that the application runs, but is unable to insert or update records in the DB - reads seem fine so far, but writes are a problem. SOME writes actually work, inserts into some small tables, but most never even make it to the DB. Using SQL Profiler, the insert / updates never make it to the server, and turning log4net up to DEBUG, and show_sql true - the select statements appear, but the insert / update statements never make it into the log at all, and never show up at the server. What's even more odd is that the application seems to be oblivious to this - the commandandclose runs without exception (open session in view with an httpmodule), the domain objects come back with uuid's generated, etc. but never get persisted. Certainly an upgrade is due, but I would hate to try it during a deployment, and without time to accurately test the app. Any ideas?

  • Custom android preference type loses focus when typing

    - by Brian
    I created a simple preference class that shows an AutoCompleteTextView control and it displays properly but when i focus on the AutoCompleteTextView and start typing it brings up the keyboard but then immediately loses focus on the control. Any idea why this loses focus? Here's what i did to create the view. the inflated layout is just a basic linear layout with a title textview in it. I could change it to a dialog preference instead I guess but it'd be smoother if it could be part of the base view. @Override protected View onCreateView(ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout layout = (LinearLayout) inflater.inflate(R.layout.base_preference, null); if (mHint != null) { TextView hintView = (TextView) layout.findViewById(R.id.PreferenceHintTextView); hintView.setText(mHint); } TextView titleView = (TextView) layout.findViewById(R.id.PreferenceTitleTextView); titleView.setText(getTitle()); AutoCompleteTextView inputView = new AutoCompleteTextView(getContext()); inputView.setGravity(Gravity.FILL_HORIZONTAL); ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(getContext(), R.layout.auto_complete_text_list_item, getEntries()); inputView.setAdapter(adapter); inputView.setThreshold(1); inputView.setOnItemSelectedListener(this); layout.addView(inputView); return layout; }

  • Backbone.js - Getting JSON back from url

    - by Brian
    While trying to learn Backbone.js, I've been trying to grab the content of a JSON file using the following code: (function($){ var MyModel = Backbone.Model.extend(); var MyCollection = Backbone.Collection.extend({ model : MyModel, url: '/backbone/data.json', parse: function(response) { console.log(response); return response; } }); var stuff = new MyCollection; console.log(stuff.fetch()); console.log(stuff.toJSON()); })(jQuery) 'stuff.fetch()' returns the entire object (with the data I'm after in responseText), 'stuff.toJSON' returns nothing ([]), but the console in the parse method is returning exactly what I want (the json object of my data). I feel like I'm missing something obvious here, but I just can't seem to figure it out why I can't get the right data out. Could someone point me in the right direction or show me what I'm doing wrong here? Am I using a model for the wrong thing?

  • Rounded image corners in IE and Firefox

    - by Brian
    I cannot make the image a background image to a div and round the div's corners because the image is resized, and as far as I know, you cannot resize a background image. What are my options, if any? Open to all suggestions including wrapper divs and corner images. Also, if it cannot be done in IE but there's a solution for Firefox, that's just fine with me.

  • Regex for Eclipse/Flash Builder File Search for comments?

    - by Brian Bishop
    In Eclipse (and Flash/Flex Builder) you get the option with Ctrl+Shift+F to do a file search and look for a regular expression. Would be a real handy thing to know. I want to find the word negate if it appears in a Flex/java comment like the following: // It was negated because or /* The negate option was.... */ or /** * We have to negate the value */ Any ideas? Will test them out at http://www.regexplanet.com/simple/index.html

  • jpa join query on a subclass

    - by Brian
    I have the following relationships in JPA (hibernate). Object X has two subclasses, Y and Z. Object A has a manyToOne relationship to object X. (Note, this is a one-sided relationship so object X cannot see object A). Now, I want to get the max value of a column in object A, but only where the relationship is of a specific subtype, ie...Y. So, that equates to...get the max value of column1 in object A, across all instances of A where they have a relationship with Y. Is this possible? I'm a bit lost as how to query it. I was thinking of something like: String query = "SELECT MAX(a.columnName) FROM A a join a.x; Query query = super.entityManager.createQuery(query); query.execute(); However that doesn't take account of the subclass of X...so I'm a bit lost. Any help would be much appreciated.

  • Glassfish complaining about JSF component IDs

    - by Brian
    Hello All I am very new to JSF (v2.0) and I am attempting to learn it at places like netbeans.org and coreservlets.com. I am working on a very simple "add/subtract/multiply/divide" Java webapp and I have run into a problem. When I first started out, the application was enter two numbers and hit a '+' key and they would be automatically added together. Now that I have added more complexity I am having trouble getting the operation to the managed bean. This is what I had when it was just "add": <h:inputText styleClass="display" id="number01" size="4" maxlength="3" value="#{Calculator.number01}" /> <h:inputText styleClass="display" id="number02" size="4" maxlength="3" value="#{Calculator.number02}" /> <h:commandButton id="add" action="answer" value="+" /> For the "answer" page, I display the answer like this: <h:outputText value="#{Calculator.answer}" /> I had the proper getters and setters in the Calculator.java managed bean and the operation worked perfectly. Now I have added the other three operations and I am having trouble visualizing how to get the operation parameter to the bean so that I can switch around it. I tried this: <h:commandButton id="operation" action="answer" value="+" /> <h:commandButton id="operation" action="answer" value="-" /> <h:commandButton id="operation" action="answer" value="*" /> <h:commandButton id="operation" action="answer" value="/" /> However, Glassfish complained that I have already used "operation" once and I am trying to use it four times here. Any adivce/tips on how to get multiple operations to the managed bean so that it can preform the desired operation? Thank you for taking the time to read.

  • Is Azure an Operating System or a Framework?

    - by Brian Genisio
    MS is calling Azure an Operating System. To me, it feels much more like a framework. I am having a bit of trouble defining the two separately. I have a general intuition, but I am not articulate enough to really say if Azure is really an OS or just a framework sitting on top of Operating Systems.

  • Static libraries in version-cross-compiled program

    - by Brian Postow
    I have a unix command line app (with big nasty makefile) that I'm trying to run on a mac. I am compiling it on a 10.6 system, with all of the appropriate libraries of course. The deployment environment is a 10.5 system, with no extra libraries. I compiled without -dynamic, and it appears to have static libraries, correctly. When I run it on the 10.6 system, it works. However, when I run it on the 10.5 system, I get: dyld: unknown required load command 0x80000022 I got this same error when I compiled things for the 10.6 system using the 10.5 xcode, so it looks like a version mis-match type problem. However, I used gcc-4.0, and $CFLAGS = -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5 so it SHOULD be set up for 10.5... any ideas? thanks Editing an ancient question: I have the exact same problem on a different computer. This time I am at 10.5.8, fully update, the same executable works on 10.6 still. Has anyone had any luck with this in the months since I asked this?

  • SQL Server 2005 I get "The database is not accessible"

    - by Brian Roisentul
    I have a computer working as a server with many SQL Server 2005 databases in it since two years ago. Today, I don't know why, when I try to connect locally to any of the databases it gives me that error. It fails even if I'm logged in using Windows Authentication or as 'sa' user. It just wouldn't let me access the databases' info. Could anybody explain me what's going on?

  • Query distinct list of choices for Django form with App Engine Datastore

    - by Brian
    I've been trying to figure this out for hours across a couple of days, and can not get it to work. I've been everywhere. I'll continue trying to figure it out, but was hoping for a quicker solution. I'm using App Engine datastore + Django. Using a query in a view and custom forms, I was able to get a list to the form but then I was not able to post. I have been trying to figure out how to dynamically add the choices as part of the Django form... I've tried various ways with no success. Help! Below are the two models. I'd like to get a distinct list of address_id to show in the location field in InfoForm. This fields could (and maybe should) be named the same, but I thought it'd be easier if they were named different. class Info(db.Model): user = db.UserProperty() location = db.StringProperty() info = db.StringProperty() created = db.DateTimeProperty(auto_now_add=True) modified = db.DateTimeProperty(auto_now=True) class Locations(db.Model): user = db.UserProperty() address_id = db.StringProperty() address = db.StringProperty() class InfoForm(djangoforms.ModelForm): info = forms.ChoiceField(choices=INFO_CHOICES) location = forms.ChoiceField() class Meta: model = Info exclude = ['user','created','modified']
