  • Noob filter: How do I refer to a string that is passed to my Ruby on Rails method from Flex as a HTT

    - by ben
    I have a HTTPService in my Flex 4 app that I call like this: getUserDetails.send(userLookup.text); In my Ruby on Rails method that this is linked to, how do I refer to the userLookup.text parameter? The method is as follows, with XXX as the placeholder: def getDetails @user = User.first (:conditions => "username = XXX") render :xml => @user end UPDATE: Is this way correct? I found it here. I'm still getting errors but it might be because of something else. def getDetails(lookupUsername) @user = User.first (:conditions => "username = '#{lookupUsername}") render :xml => @user end Thanks for reading!

  • C++ - Opening a file inside a function using fopen. (Noob problem)

    - by Josh
    I am using Visual Studio 2005 (C++). I am passing a string into a function as a char array. I want to open the file passed in as a parameter and use it. I know my code works to an extent, because if I hardcode the filename as the first parameter it works perfectly. I do notice if I look at the value as a watch, the value includes the address aside the string literal. I have tried passing in the filename as a pointer, but it then complains about type conversion with __w64. As I said before it works fine with "filename.txt" in place of fileName. I am stumped. void read(char fileName[50],int destArray[MAX_R][MAX_C],int demSize[2]) { int rows=0; int cols=0; int row=0; int col=0; FILE * f = fopen(fileName,"r"); ...

  • git noob : why does "git push origin master" fail to github ?

    - by anjanb
    hi there, Here are the steps I took. I created a repository on github and generated a rails project on my windows vista home premium (which has msys git 1.7.0.2). 3) I then committed the generated files 4) g it remote add origin [email protected]:anjanb/Jobs2Go.git git push origin master On the 5th step, I get the following error. "Permission denied (publickey). fatal: The remote end hung up unexpectedly" I vaguely remember following some sshgen steps I took when I created my 1st github repository but I have forgotten what it was. Can someone point me what I did wrong, what I need to do right. Thank you,

  • Rails - session information being cleared?

    - by Jty.tan
    Hi! I'm having a weird issue that I can't track down... For context, I have resources of Users, Registries, and Giftlines. Each User has many Registries. Each Registry has many Giftlines. It's a belongs to association for them in a reverse manner. What is basically happening, is that when I am creating a giftline, the giftline itself is created properly, and linked to its associated Registry properly, but then in the process of being redirected back to the Registry show page, the session[:user_id] variable is cleared and I'm logged out. As far as I can tell, where it goes wrong is here in the registries_controller: def show @registry = Registry.find(params[:id]) @user = User.find(@registry.user_id) if (params[:user_id] && (@user.login != params[:user_id]) ) flash[:notice] = "User #{params[:user_id]} does not have such a registry." redirect_to user_registries_path(session[:user_id]) end end Now, to be clear, I can do a show of the registry normally, and nothing weird happens. It's only when I've added a giftline does the session[:user_id] variable get cleared. I used the debugger and this is what seems to be happening. (rdb:19) list [20, 29] in /Users/kriston/Dropbox/ruby_apps/bee_registered/app/controllers/registries_controller.rb 20 render :action => 'new' 21 end 22 end 23 24 def show => 25 @registry = Registry.find(params[:id]) 26 @user = User.find(@registry.user_id) 27 if (params[:user_id] && (@user.login != params[:user_id]) ) 28 flash[:notice] = "User #{params[:user_id]} does not have such a registry." 29 redirect_to user_registries_path(session[:user_id]) (rdb:19) session[:user_id] "tester" (rdb:19) So from there we can see that the code has gotten back to the show command after the item had been added, and that the session[:user_id] variable is still set. (rdb:19) list [22, 31] in /Users/kriston/Dropbox/ruby_apps/bee_registered/app/controllers/registries_controller.rb 22 end 23 24 def show 25 @registry = Registry.find(params[:id]) 26 @user = User.find(@registry.user_id) => 27 if (params[:user_id] && (@user.login != params[:user_id]) ) 28 flash[:notice] = "User #{params[:user_id]} does not have such a registry." 29 redirect_to user_registries_path(session[:user_id]) 30 end 31 end (rdb:19) session[:user_id] "tester" (rdb:19) Stepping on, we get to this point. And the session[:user_id] is still set. At this point, the URL is of the format localhost:3000/registries/:id, so params[:user_id] fails, and the if condition doesn't occur. (Unless I am completely wrong .<) So then the next bit occurs, which is (rdb:19) list [1327, 1336] in /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb 1327 end 1328 1329 def perform_action 1330 if action_methods.include?(action_name) 1331 send(action_name) => 1332 default_render unless performed? 1333 elsif respond_to? :method_missing 1334 method_missing action_name 1335 default_render unless performed? 1336 else (rdb:19) session[:user_id] "tester" And then when I hit next... (rdb:19) next 2: session[:user_id] = /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/filters.rb:618 return index if nesting != 0 || aborted (rdb:19) list [613, 622] in /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/filters.rb 613 private 614 def call_filters(chain, index, nesting) 615 index = run_before_filters(chain, index, nesting) 616 aborted = @before_filter_chain_aborted 617 perform_action_without_filters unless performed? || aborted => 618 return index if nesting != 0 || aborted 619 run_after_filters(chain, index) 620 end 621 622 def run_before_filters(chain, index, nesting) (rdb:19) session {:user_id=>nil, :session_id=>"49992cdf2ddc708b441807f998af7ddc", :return_to=>"/registries", "flash"=>{}, :_csrf_token=>"xMDI0oDaOgbzhQhDG7EqOlGlxwIhHlB6c71fWgOIKcs="} The session[:user_id] is cleared, and when the page renders, I'm logged out. .< Sooo.... Any idea why this is occurring? It just occurred to me that I'm not sure if I'm meant to be pasting large chunks of debug output in here... Somebody point out to me if I'm not meant to be doing this. . And yes, this only occurs when I have added a giftitem, and it is sending me back to the registry page. When I'm viewing it, the same code occurs, but the session[:user_id] variable isn't cleared. It's driving me mildly insane. Thanks!

  • QT NOOB: Add action handler for multiple objects of same type.

    - by what
    I have a simple QT application with 10 radio buttons with names radio_1 through radio_10. It is a ui called Selector, and is part of a class called TimeSelector In my header file for this design, i have this: //! [1] class TimeSelector : public QWidget { Q_OBJECT public: TimeSelector(QWidget *parent = 0); private slots: //void on_inputSpinBox1_valueChanged(int value); //void on_inputSpinBox2_valueChanged(int value); private: Ui::Selector ui; }; //! [1] the commented out void_on_inputSpinBox1_valueChanged(int value) is from the tutorial for the simple calculator. I know i can do: void on_radio_1_valueChanged(int value); but I would need 10 functions. I want to be able to make one function that works for everything, and lets me pass in maybe a name of the radio button that called it, or a reference to the radio button so i can work with it and determine who it was. I am very new to QT but this seems like it should be very basic and doable, thanks.

  • jQuery noob: change border color of element on hover of another element.

    - by Kyle Sevenoaks
    I'd try to explain what I mean, but there is an easier way: click here for jsfiddle example. Basically I want the border color of the div rfrsh_btn to change when productOptionsMenu is hovered over. I'm using jQuery with the .noConflict var because this site also uses Prototype. jQuery: var $j = jQuery.noConflict(); $j(".productOptionsMenu").hover( function () { $j(#rfrsh_btn).css({"border-color":"#85c222"}); }; ); Thanks :)

  • Noob here, but wanting to try and make my own app.

    - by Justin
    Hi all, I have a small amount of programing experience with Siemens and Allen Bradley but would like to make my own app for a certain website I frequent. I would like the website to be a little more user friendly for me instead of having to open browser etc. Is it possible to have a simple forum translated into a widget so you can see the forum posts and post from there? The website in question is http://vnboards.ign.com Any ideas or suggestions no matter how bad are appreciated. If it isnt worth attempting or my skills may not be up to par, feel free to say so :P Dont pull any punches :) Thanks! Justin

  • Noob question: Draw a quad parallel to the view.

    - by Jack
    Hi all, ok what I want to do is to draw a quad in the scene that lays on a plane parallel to the view. So it should appear flat. More in particular, I think I didn't get very well how the mechanism of gluLookAt works in comparison with the functions glTranslate and glRotate: If I position the view "manually" using the functions glTranslate and glRotate whenever I draw an object its position is relative to the current view. And I understand that this is due to the transformation matrix in the stack. However when I use the gluLookAt that should automatically set the view, the coordinates of the object I want to draw must be "absolute" to show it properly. Thanks in advance.

  • How to propagate http response code from back-end to client

    - by Manoj Neelapu
    Oracle service bus can be used as for pass through casses. Some use cases require propagating the http-response code back to the caller. http://forums.oracle.com/forums/thread.jspa?messageID=4326052&#4326052 is one such example we will try to accomplish in this tutorial.We will try to demonstrate this feature using Oracle Service Bus (11.1.1.3.0. We will also use commons-logging-1.1.1, httpcomponents-client-4.0.1, httpcomponents-core-4.0.1 for writing the client to demonstrate.First we create a simple JSP which will always set response code to 304.The JSP snippet will look like <%@ page language="java"     contentType="text/xml;     charset=UTF-8"        pageEncoding="UTF-8" %><%      System.out.println("Servlet setting Responsecode=304");    response.setStatus(304);    response.flushBuffer();%>We will now deploy this JSP on weblogic server with URI=http://localhost:7021/reponsecode/For this JSP we will create a simple Any XML BS We will also create proxy service as shown below Once the proxy is created we configure pipeline for the proxy to use route node, which invokes the BS(JSPCaller) created in the first place. So now we will create a error handler for route node and will add a stage. When a HTTP BS sends a request, the JSP sends the response back. If the response code is not 200, then the http BS will consider that as error and the above configured error handler is invoked. We will print $outbound to show the response code sent by the JSP. The next actions. To test this I had create a simple clientimport org.apache.http.Header;import org.apache.http.HttpEntity;import org.apache.http.HttpHost;import org.apache.http.HttpResponse;import org.apache.http.HttpVersion;import org.apache.http.client.methods.HttpGet;import org.apache.http.conn.ClientConnectionManager;import org.apache.http.conn.scheme.PlainSocketFactory;import org.apache.http.conn.scheme.Scheme;import org.apache.http.conn.scheme.SchemeRegistry;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpParams;import org.apache.http.params.HttpProtocolParams;import org.apache.http.util.EntityUtils;/** * @author MNEELAPU * */public class TestProxy304{    public static void main(String arg[]) throws Exception{     HttpHost target = new HttpHost("localhost", 7021, "http");     // general setup     SchemeRegistry supportedSchemes = new SchemeRegistry();     // Register the "http" protocol scheme, it is required     // by the default operator to look up socket factories.     supportedSchemes.register(new Scheme("http",              PlainSocketFactory.getSocketFactory(), 7021));     // prepare parameters     HttpParams params = new BasicHttpParams();     HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);     HttpProtocolParams.setContentCharset(params, "UTF-8");     HttpProtocolParams.setUseExpectContinue(params, true);     ClientConnectionManager connMgr = new ThreadSafeClientConnManager(params,              supportedSchemes);     DefaultHttpClient httpclient = new DefaultHttpClient(connMgr, params);     HttpGet req = new HttpGet("/HttpResponseCode/ProxyExposed");     System.out.println("executing request to " + target);     HttpResponse rsp = httpclient.execute(target, req);     HttpEntity entity = rsp.getEntity();     System.out.println("----------------------------------------");     System.out.println(rsp.getStatusLine());     Header[] headers = rsp.getAllHeaders();     for (int i = 0; i < headers.length; i++) {         System.out.println(headers[i]);     }     System.out.println("----------------------------------------");     if (entity != null) {         System.out.println(EntityUtils.toString(entity));     }     // When HttpClient instance is no longer needed,      // shut down the connection manager to ensure     // immediate deallocation of all system resources     httpclient.getConnectionManager().shutdown();     }}On compiling and executing this we see the below output in STDOUT which clearly indicates the response code was propagated from Business Service to Proxy serviceexecuting request to http://localhost:7021----------------------------------------HTTP/1.1 304 Not ModifiedDate: Tue, 08 Jun 2010 16:13:42 GMTContent-Type: text/xml; charset=UTF-8X-Powered-By: Servlet/2.5 JSP/2.1----------------------------------------

  • How to pass alias through sudo

    - by Tanktalus
    I have an alias that passes in some parameters to a tool that I use often. Sometimes I run as myself, sometimes under sudo. Unfortunately, of course, sudo doesn't recognise the alias. Does anyone have a hint on how to pass the alias through? In this case, I have a bunch of options for perl when I'm debugging: alias pd='perl -Ilib -I/home/myuser/lib -d' Sometimes, I have to debug my tools as root, so, instead of running: pd ./mytool --some params I need to run it under sudo. I've tried many ways: sudo eval $(alias pd)\; pd ./mytool --some params sudo $(alias pd)\; pd ./mytool --some params sudo bash -c "$(alias pd)\; pd ./mytool --some params" sudo bash -c "$(alias pd); pd ./mytool --some params" sudo bash -c eval\ "$(alias pd)\; pd ./mytool --some params" sudo bash -c eval\ "'$(alias pd)\; pd ./mytool --some params'" I was hoping for a nice, concise way to ensure that my current pd alias was fully used (in case I need to tweak it later), though some of my attempts weren't concise at all. My last resort is to put it into a shell script and put that somewhere that sudo will be able to find. But aliases are soooo handy sometimes, so it is a last resort.

  • Flex HttpService POST limited to 543 Byte per Form field?

    - by motto
    Hi, I am getting a FaultEvent when trying to send form fields through HTTPService that contain more than 542 chars. Initializing the HttpService: httpServ = new HTTPService(); httpServ.method = 'POST'; httpServ.url = ENDPOINT_URL; //http://localhost:3001/ReportError.aspx httpServ.resultFormat = HTTPService.RESULT_FORMAT_TEXT; httpServ.contentType = HTTPService.CONTENT_TYPE_FORM; httpServ.addEventListener(ResultEvent.RESULT, OnErrorSent); httpServ.addEventListener(FaultEvent.FAULT, OnFault); Sending the request: var params:Object = {}; //params["stack"] = e.stackTrace.slice(0, 542); //length 542 = works //params["stack2"] = e.stackTrace.slice(1, 543); //length 542 = works (just to show that it's not about the content itself) params["stack3"] = e.stackTrace.slice(0, 543); //length 543 = fails I also seem to be able to create many form fields (with 542 length) so that it's not a limit of the request itself but of the form field: var params:Object = {}; params["stack"] = e.stackTrace.slice(0, 542); //length 542 params["stack2"] = e.stackTrace.slice(1, 543); //length 542 params["stack3"] = e.stackTrace.slice(2, 544); //length 542 // Length > 1600 chars The receiving party is an ASP.NET 4 site on the same domain and port. I hope someone already came across a similar restrictions or has some general advice on how to trace this problem down further. Thanks in advance.

  • need help fixing unique key in rails. rails is adding id causing duplicate key

    - by railsnew
    I need some help in fixing the below issue. I had transaction blocks in my rails code like below: @sqlcontact = "INSERT INTO contacts (id,\"cid\", \"hphone\", mphone, provider, cemail, email, sms , mail, phone) VALUES ('"+@id1+"','" + @id1 + "', '"+ params[:hphone] + "', '"+params[:mphone]+ "', '" + params[:provider] + "', '" + params[:cemail]+ "', '" + @varemail+ "', '"+@varsms+ "', '"+ @varmail+"', '"+@varphone+"')" my app was deployed to heroku so I was advised by them to remove transaction blocks. So I changed the above to: @cont = Contact.new(:id => @id1, :cid => @id1, :hphone => params[:hphone], :mphone => params[:mphone], :provider => params[:provider], :cemail => params[:cemail], :email => @varemail, :sms => @varsms, :mail => @varmail, :phone => @varphone) @cont.save My app also already had data stored. Now the problem is that when I try to save a record ...I keep getting the error: duplicate key value violates unique constraint "contacts_pkey" The error also shows the sql query trying to insert data ...however, in that sql query i Do not see id value. As you can see from my code that I am passing the id. then why is rails not accepting it? does it always include its own sequential id? can I not overwrite the default rails magic? and if it does that...does it not look at data that is already in the DB?? I am really stuck here. What should I do? should I just go back to my transaction block

  • What's the best way to refactor this Rails controller?

    I'd like some advice on how to best refactor this controller. The controller builds a page of zones and modules. Page has_many zones, zone has_many modules. So zones are just a cluster of modules wrapped in a container. The problem I'm having is that some modules may have some specific queries that I don't want executed on every page, so I've had to add conditions. The conditions just test if the module is on the page, if it is the query is executed. One of the problems with this is if I add a hundred special module queries, the controller has to iterate through each one. I think I would like to see these module condition moved out of the controller as well as all the additional custom actions. I can keep everything in this one controller, but I plan to have many apps using this controller so it could get messy. class PagesController < ApplicationController # GET /pages/1 # GET /pages/1.xml # Show is the main page rendering action, page routes are aliased in routes.rb def show #-+-+-+-+-Core Page Queries-+-+-+-+- @page = Page.find(params[:id]) @zones = @page.zones.find(:all, :order => 'zones.list_order ASC') @mods = @page.mods.find(:all) @columns = Page.columns # restful params to influence page rendering, see routes.rb @fragment = params[:fragment] # render single module @cluster = params[:cluster] # render single zone @head = params[:head] # render html, body and head #-+-+-+-+-Page Level Json Conversions-+-+-+-+- @metas = @page.metas ? ActiveSupport::JSON.decode(@page.metas) : nil @javascripts = @page.javascripts ? ActiveSupport::JSON.decode(@page.javascripts) : nil #-+-+-+-+-Module Specific Queries-+-+-+-+- # would like to refactor this process @mods.each do |mod| # Reps Module Custom Queries if mod.name == "reps" @reps = User.find(:all, :joins => :roles, :conditions => { :roles => { :name => 'rep' } }) end # Listing-poc Module Custom Queries if mod.name == "listing-poc" limit = params[:limit].to_i < 1 ? 10 : params[:limit] PropertyEntry.update_from_listing(mod.service_url) @properties = PropertyEntry.all(:limit => limit, :order => "city desc") end # Talents-index Module Custom Queries if mod.name == "talents-index" @talent = params[:type] @reps = User.find(:all, :joins => :talents, :conditions => { :talents => { :name => @talent } }) end end respond_to do |format| format.html # show.html.erb format.xml { render :xml => @page.to_xml( :include => { :zones => { :include => :mods } } ) } format.json { render :json => @page.to_json } format.css # show.css.erb, CSS dependency manager template end end # for property listing ajax request def update_properties limit = params[:limit].to_i < 1 ? 10 : params[:limit] offset = params[:offset] @properties = PropertyEntry.all(:limit => limit, :offset => offset, :order => "city desc") #render :nothing => true end end So imagine a site with a hundred modules and scores of additional controller actions. I think most would agree that it would be much cleaner if I could move that code out and refactor it to behave more like a configuration.
