  • active_scaffold routing error

    - by Elizabeth Buckwalter
    If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works. [/Edit] ActionController::RoutingError in Departments#index Showing vendor/plugins/active_scaffold/frontends/default/views/_list_header.html.erb where line #8 raised: No route matches {:_method=:get, :action="show_search", :controller="departments"} Extracted source (around line #8): 5: <% next if controller.respond_to? link.security_method and !controller.send(link.security_method) -%> 6: <% next if link.action == 'new' && params[:nested].nil? && active_scaffold_config.list.always_show_create %> 7: <% next if link.action == 'show_search' && active_scaffold_config.list.always_show_search %> 8: <%= render_action_link(link, new_params) -%> 9: <% end -%> 10: 11: <%= loading_indicator_tag(:action => :table) %> Trace of template inclusion: vendor/plugins/active_scaffold/frontends/default/views/list.html.erb Full Trace It was taking forever to format it.

  • How do I run a ruby script, that I put in my /lib/tasks/ directory in my Rails app, once?

    - by marcamillion
    Eventually I would like to get to setting it up as a Rake task and do a cron job, but for right now...all I want to do is take my ruby script that used to work as a standalone script and have it work within my Rails app. I renamed the file to be .rake instead of .rb and tried doing rake my_script at the command-line, but that gave me this error message: rake aborted! Don't know how to build task 'my_script' (See full trace by running task with --trace) How do I run this script within my Rails environment? This is the first time I am doing something like this, so any assistance would be greatly appreciated. Thanks.

  • Adding info to an exception

    - by NoozNooz42
    I'd like to add information to a stack trace/exception. Basically I've got something like this as of now, which I really like: Exception in thread "main" java.lang.ArithmeticException: / by zero at com.so.main(SO.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke However I'd like to catch that exception and add additional info to it, while still having the original stack trace. For example, I'd like to have that: Exception in thread "main" CustomException: / by zero (you tried to divide 42 by 0) at com.so.main(SO.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke So basically I want to catch the ArithmeticException and rethrow, say, a CustomException (adding "you tried to divide 42 by 0" in this example) while still keeping the stacktrace from the original ArithmeticException. What is the correct way to do this in Java? Is the following correct: try { .... } catch (ArithmeticException e) { throw new CustomException( "You tried to divide " + x + " by " + y, e ); }

  • How to View Android Native Code Profiling?

    - by David R.
    I started my emulator with ./emulator -trace profile -avd emulator_15. I then tracked down the trace files to ~/.android/avd/rodgers_emulator_15.avd/traces/profile, where there are six files: qtrace.bb, qtrace.exc, qtrace.insn, qtrace.method, qtrace.pid, qtrace.static. I can't figure out what to do with these files. I've tried both dmtracedump and traceview on all of the files, but none seem to generate any output I can do anything with. How can I view the proportion of time taken by native method calls on Android?

  • How do I store keys pressed

    - by Glycerine
    I would like to store keys pressed when I listen out for the keyDown on the stage. I can add the listener fine, but I'm not getting the character I want out of the event to store it into a string. This is what I have so far: private var _addToString:String = ""; public function Hotwire() { this.addEventListener(KeyboardEvent.KEY_DOWN, keydownEventHandler); } private function keydownEventHandler(ev:KeyboardEvent):void { trace("Key pressed: " + ev.charCode ); addToString(ev.charCode); } private function addToString(value:uint):String { trace(_addToString); return _addToString += String.fromCharCode(value); } Every key I press its returns '0'. How do I convert the chatCode to a real alphanumeric character I can read later? Thanks in advance

  • Cap deploy doesn't work all the sudden; something to do with FactoryGirl and assets

    - by Jason Swett
    I've been cap deploying my app all throughout it development, and this last time I tried to deploy it, it didn't work. Here's what happened: * executing `deploy:assets:precompile' * executing "cd /var/www/oneteam/releases/20121006153136 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile" servers: ["electricsasquatch.com"] [electricsasquatch.com] executing command ** [out :: electricsasquatch.com] rake aborted! ** [out :: electricsasquatch.com] uninitialized constant OneTeam::Application::FactoryGirl ** [out :: electricsasquatch.com] ** [out :: electricsasquatch.com] (See full trace by running task with --trace) It looks like it failed on the deploy:assets:precompile command. I don't get why that command would have tried to do anything with FactoryGirl, though. Any ideas?

  • Generating JavaDoc style documentation

    - by Walter White
    Hi all, I would like to generate a report similar to JavaDoc so that you can real easily click on a test, result, and source. I am running HtmlUnit tests so I will have the result (html), source (request, headers, parameters, etc.), stack trace all visible so a developer or qa can go back later to review this to see what went awry. So, in the left frame, the tests will be listed along with the group they were a part of (similar to packages in javadoc). In the right frame, the results will be presented along with the source and stack trace. How can I achieve this? The HtmlUnit tests are part of the project and not a stand-alone plugin if that matters. Thanks, Walter

  • redis timeout with predis

    Hello, I'm using redis with php (predis at http://github.com/nrk/predis/) and am experiencing frequent timeout.

  • Sharepoint web part stops working because of Resources.en-US.resx file

    - by Eric C
    I've been developing a Sharepoint web part, which had been working fine upon deployment. The web part has been developed with WSP Builder, packaged up and then deployed via stsadm. The web part has been deployed tens, if not a hundred times to the dev box with no problems. Now, the web part throws an error which breaks the page it's on: Object reference not set to an instance of an object.

I've retracted the web part manually through Solution Management, retracted through stsadm, checked for the existence of the resource file, which is nowhere to be found. I'm pretty much at a loss to why this happened or how to resolve it.

  • ASP.NET application developed in 32 bit environment not working in 64 bit environment

    - by jgonchik
    We have developed an ASP.NET website on a Windows 7 - 32 bit platform using Visual Studio 2008. This website is being hosted at a hosting company where we share a server with hundreds of other ASP.NET websites. We are in the process of changing our hosting to a dedicated Windows 2008 - 64 bit server. We have installed Visual Studio on this new server in order to debug our application. If we try to start the application on this new server using Visual Studios 2008's own web server (not IIS 7) we get the error below. We have tried to compile the application in both 32 as well as 64 bit mode. We also tried to compile to "Any CPU". But nothing helps. We also tried running Visual Studio as an administrator but without success. We get the following error: Server Error in '/' Application. The specified module could not be found.

  • WinForms: Why do I get InvalidCastException when showing folder browser dialog?

    - by Marek
    I am randomly getting InvalidCastException when showing FolderBrowserDialog and also many clients have reported this. I have not been able to find anything relevant on the internet. Does anyone know what causes this/how to fix this? My code: using (FolderBrowserDialog fbd = new FolderBrowserDialog()) { fbd.ShowNewFolderButton = false; if (fbd.ShowDialog() == DialogResult.OK) Stack trace: Error: System.InvalidCastException: 'Unable to cast object of type 'System.__ComObject' to type 'IMalloc'.'.

When running out of debugger, it happens only very rarely (happened once or twice in 6 months) on my 64 bit Windows 7 and goes away after restart. The clients are certainly not running the app in debugger so it is surely reproducible out of debugger.

  • A SelfHosted WCF Service over Basic HTTP Binding doesn't support more than 1000 concurrent requests

    - by Krishnan
    I have self hosted a WCF Service over BasicHttpBinding consumed by an ASMX Client. I'm simulating a concurrent user load of 1200 users. The service method takes a string parameter and returns a string. The data exchanged is less than 10KB. The processing time for a request is fixed at 2 seconds by having a Thread.Sleep(2000) statement. Nothing additional. I have removed all the DB Hits / business logic. The same piece of code runs fine for 1000 concurrent users. I get the following error when I bump up the number to 1200 users. System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at WCF.Throttling.Client.Service.Function2(String param) This exception is often reported on DataContract mismatch and large data exchange.

  • Actionscript base class in Flex AIR app

    - by Alan
    I'm trying to build a Flex AIR app using Flex Builder 3, which I'm just getting started with. In Flash CS4, there's a text field in the authoring environment where you can specify a class that will become the "base" class - your class inherits from Sprite and then "becomes" the Stage at runtime. Is there a a way to do the same thing with Flex/AIR? Failing that, can anyone explain how to create and use an external class? Originally I had this in TestApp.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> </mx:WindowedApplication> And this in TestApp.as: package { public class TestApp { public function TestApp() { trace('Hello World'); } } } That gives the error "packages cannot be nested", so I tried taking out the package statement: public class TestApp { public function TestApp() { trace('Hello World'); } } That gives an error "classes cannot be nested", so I finally gave up and tried to take out the class altogether, figuring I'd try to start with a bunch of functions instead: function init() { trace('Hello World'); } But that gives the error "A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package". I can't win! When I put my class in a package, it says I can't do that because it would be nested. When I don't, it says it needs to be in a package so it can be seen. Does anyone know how to fix this? If I can't do the custom-class-as-base-class thing, is there a way I could just have it like: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> <mx:Script> var app = new TestApp(); </mx:Script> </mx:WindowedApplication> At the moment I can't import the class definition at all, so even that won't work. Thanks in advance!

  • "Attach to process" missing from Delphi 7's Run menu

    - by glob
    I have to resurrect an ancient Delphi 7 application, which means I have to use the D7 IDE. Upgrading the project to a more recent version of Delphi unfortunately isn't an option. My new D7 installation's Run menu is missing Attach to Process. Aside from the missing menu item, the debugger works fine (I can debug normal Delphi executables started with Run). I know D7 supported this feature (it's in the help file), so does anyone have any idea what I've missed? The installation is Delphi 7 Enterprise (Version 7.0 Build 4.453).

I've tried all manner of pluralization/singular, removing the attr_accessible altogether, and who knows what else. restaurant.rb: # == RESTAURANT MODEL # # Table name: restaurants # # id :integer not null, primary key # name :string(255) # created_at :datetime not null # updated_at :datetime not null # class Restaurant < ActiveRecord::Base attr_accessible :name, :job_attributes has_many :jobs has_many :users, :through => :jobs has_many :positions accepts_nested_attributes_for :jobs, :allow_destroy => true validates :name, presence: true end job.rb: # == JOB MODEL # # Table name: jobs # # id :integer not null, primary key # restaurant_id :integer # shortname :string(255) # user_id :integer # created_at :datetime not null # updated_at :datetime not null # class Job < ActiveRecord::Base attr_accessible :restaurant_id, :shortname, :user_id belongs_to :user belongs_to :restaurant has_many :shifts validates :name, presence: false end restaurants_controller.rb: class RestaurantsController < ApplicationController before_filter :logged_in, only: [:new_restaurant] def new @restaurant = Restaurant.new @user = current_user end def create @restaurant = Restaurant.new(params[:restaurant]) if @restaurant.save flash[:success] = "Restaurant created." redirect_to welcome_path end end end new.html.erb: <% provide(:title, 'Restaurant') %> <%= form_for @restaurant do |f| %> <%= render 'shared/error_messages' %> <%= f.label "Restaurant Name" %> <%= f.text_field :name %> <%= f.fields_for :job do |child_f| %> <%= child_f.label "Nickname" %> <%= child_f.text_field :shortname %> <% end %> <%= f.submit "Done", class: "btn btn-large btn-primary" %> <% end %> Output Parameters: {"utf8"=>"?", "authenticity_token"=>"DjYvwkJeUhO06ds7bqshHsctS1M/Dth08rLlP2yQ7O0=", "restaurant"=>{"name"=>"The Pink Door", "job"=>{"shortname"=>"PD"}}, "commit"=>"Done"} The error i'm receiving is: ActiveModel::MassAssignmentSecurity::Error in RestaurantsController#create Cant mass-assign protected attributes: job Rails.root: /home/johnnyfive/Dropbox/Projects/sa Application Trace | Framework Trace | Full Trace app/controllers/restaurants_controller.rb:11:in `new' app/controllers/restaurants_controller.rb:11:in `create' Anyone have ANY clue how to get this to work?

  • Flash AS3 button eventlistener array bug

    - by Tyler Pepper
    Hi there, this is my first time posting a question here. I have an array of 12 buttons on a timeline that when first visiting that part of the timeline, get a CLICK eventlistener added to them using a for loop. All of them work perfectly at that point. When you click one it plays a frame label inside the specific movieClip and reveals a bio on the corresponding person with a close button and removes the CLICK eventlisteners for each button, again using a for loop. The close button plays a closing animation, and then the timeline goes back to the first frame (the one with the 12 buttons on it) and the CLICK eventlisteners are re-added, but now only the first 9 buttons of the array work. There are no output errors and the code to re-add the eventlisteners is exactly the same as the first time that works. I am completely at a loss and am wondering if anyone else has run into this problem. All of my buttons are named correctly, there are absolutely no output errors (I've used the debug module) and I made sure the array with the buttons in it is outputting all 12 at the moment the close button is clicked to add the eventlisteners back. for (var q = 0; q < ackBoDBtnArray.length; q++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[q]].addEventListener(MouseEvent.CLICK, showBio); } private function showBio(eo:MouseEvent):void { trace("show the bio"); bodVar = ackBoDBtnArray.getIndex(eo.target.name); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDPgArray[bodVar]); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.addEventListener(MouseEvent.CLICK, hideBio); for (var r = 0; r < ackBoDBtnArray.length; r++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].mouseEnabled = false; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].removeEventListener(MouseEvent.CLICK, showBio); } } private function hideBio(eo:MouseEvent):void { trace("hide it!"); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.removeEventListener(MouseEvent.CLICK, hideBio); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDClosePgArray[bodVar]); for (var s = 0; s < ackBoDBtnArray.length; s++){ trace(ackBoDBtnArray[s]); contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].mouseEnabled = true; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].addEventListener(MouseEvent.CLICK, showBio); } Thanks in advance for any help and insight you can provide...I have a slight feeling that its something that may be obvious to another set of eyes...haha.

  • Reading what is in the vsdiagnostics blob in Azure (1.7)

    - by tomasmcguinness
    I've enabled Diagnostics in one of my Worker roles and published it to Azure. There was a new blob container created called "vsdiagnostics" and contained within in are two binary files. I'm assuming that these files contain the output of my Trace statements, but I'm unable to open these files as I have no idea what format they are in. I've not found anything on www.windowsazure.com about it and most of the tools they recommend are very outdated. I have installed Cerebrata's Azure Diagnostics Manager, but that isn't able to load the Trace Logs. If anyone could point me in the right direction I'd be grateful!

  • What is the performance impact of tracing in C# and ASP.NET?

    - by SkippyFire
    I found this in some production login code I was looking at recently... HttpContext.Current.Trace.Write(query + ": " + username + ", " + password)); ...where query is a short SQL query to grab matching users. Does this have any sort of performance impact? I assume its very small. Also, what is the purpose of this exact type of trace, using the HTTP Context? Where does this data get traced to? Thanks in advance!

  • Getting Bad file descriptor when running Tornado AsyncHTTPTestCase

    - by Will
    When running a test using the Tornado AsyncHTTPTestCase I'm getting a stack trace that isn't related to the test. The test is passing so this is probably happening on the test clean up? I'm using Python 2.7.2, Tornado 2.2. The test code is: class AllServersHandlerTest(AsyncHTTPTestCase): endpoint = AllServersHandler.endpoint # '/rest/test/' def test_server_status_with_advertiser(self): on_new_host(None, '127.0.0.1') response = self.fetch(self.endpoint, method='GET') result = json.loads(response.body, 'utf8').get('data') self.assertEquals(['127.0.0.1'], result) The test passes ok, but I get the following stack trace from the Tornado server. OSError: [Errno 9] Bad file descriptor INFO:root:200 POST /rest/serverStatuses (127.0.0.1) 0.00ms DEBUG:root:error closing fd 688 Traceback (most recent call last): File "C:\Python27\Lib\site-packages\tornado-2.2-py2.7.egg\tornado\ioloop.py", line 173, in close os.close(fd) OSError: [Errno 9] Bad file descriptor Any ideas how to cleanly shutdown the test case?
