  • Count warnings in Python 2.4

    - by l0b0
    I've got some tests that need to count the number of warnings raised by a function. In Python 2.6 this is simple, using with warnings.catch_warnings(record=True) as warn: ... self.assertEquals(len(warn), 2) Unfortunately, with is not available in Python 2.4, so what else could I use? I can't simply check if there's been a single warning (using warning filter with action='error' and try/catch), because the number of warnings is significant.

  • RSpec mocking a nested model in Rails - ActionController problem

    - by emson
    Hi All I am having a problem in RSpec when my mock object is asked for a URL by the ActionController. The URL is a Mock one and not a correct resource URL. I am running RSpec 1.3.0 and Rails 2.3.5 Basically I have two models. Where a subject has many notes. class Subject < ActiveRecord::Base validates_presence_of :title has_many :notes end class Note < ActiveRecord::Base validates_presence_of :title belongs_to :subject end My routes.rb file nests these two resources as such: ActionController::Routing::Routes.draw do |map| map.resources :subjects, :has_many => :notes end The NotesController.rb file looks like this: class NotesController < ApplicationController # POST /notes # POST /notes.xml def create @subject = Subject.find(params[:subject_id]) @note = @subject.notes.create!(params[:note]) respond_to do |format| format.html { redirect_to(@subject) } end end end Finally this is my RSpec spec which should simply post my mocked objects to the NotesController and be executed... which it does: it "should create note and redirect to subject without javascript" do # usual rails controller test setup here subject = mock(Subject) Subject.stub(:find).and_return(subject) notes_proxy = mock('association proxy', { "create!" => Note.new }) subject.stub(:notes).and_return(notes_proxy) post :create, :subject_id => subject, :note => { :title => 'note title', :body => 'note body' } end The problem is that when the RSpec post method is called. The NotesController correctly handles the Mock Subject object, and create! the new Note object. However when the NoteController#Create method tries to redirect_to I get the following error: NoMethodError in 'NotesController should create note and redirect to subject without javascript' undefined method `spec_mocks_mock_url' for #<NotesController:0x1034495b8> Now this is caused by a bit of Rails trickery that passes an ActiveRecord object (@subject, in our case, which isn't ActiveRecord but a Mock object), eventually to url_for who passes all the options to the Rails' Routing, which then determines the URL. My question is how can I mock Subject so that the correct options are passed so that I my test passes. I've tried passing in :controller = 'subjects' options but no joy. Is there some other way of doing this? Thanks...

  • How many disks is too many in this RAID 5 configuration??

    - by Tom
    HP 2012i SAN, 7 disks in RAID 5 with 1 hot spare, took several days to expand the volume from 5 to 7 300GB SAS drives. Looking for suggestions about when and how I would determine that having 2 volumes in the SAN, each one with RAID 5, would be better?? I can add 3 more drives to the controller someday, the SAN is used for ESX/vSphere VMs. Thank you...

  • UIViewController not oreintating. Methods not called

    - by capple
    Greetings, This question does seem to be an ongoing saga in the world of iphone SDK... so heres my contribution... Had two separate projects from the same template... one semi-works, the other not at all... Please let me explain my steps... used this basic GL ES template //iphonedevelopment.blogspot.com/2008/12/opengl-project-template-for-xcode.html had to sort out some of the 'Release' configuration but otherwises has eveything I need to add orientation to a GL ES project. One my first project, did my stuff, then added these methods.... -(BOOL)shouldAutoRotateToInterfaceOrientation ..... -(void)willRotateToInterfaceOrientation .... -(void)didRotateFromInterfaceOrientation .... -(void)willAnimateRotationToInterfaceOrientation .... And understand what they do (or are trying to do in my case), the (BOOL)should... gets called once when the view controller is created, and returns 'YES'. But after that none of the other methods are called! So I started from scratch with a blank template (GL ES one from above)...and added minimum to support auto rotation. But this time none of the methods get called! So I investigated .... //developer.apple.com/iphone/library/qa/qa2010/qa1688.html as it said, I added the GLViewController.view first, then added the GLview as subviews of the application delegate. Nothing! Then found this //www.iphonedevsdk.com/forum/iphone-sdk-development/44993-how-determine-ipad-launch-orientation.html which states to enable orientation notifications [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; and then subsequently disable them in the view controller... makes sense...did it, nothing... I think the notifications might be on by default though, since I didn't need to enable them in the first project, yet it still try to verify a orientation (i.e (BOOL)shouldAutoRotate... )... If any one could help me out it would be greatly appreciated as this issue is driving me insane. Thanks in advance. The code can be found here ... http://rapidshare.com/files/392053688/autoRotation.zip N.B These projects avoid nib/xib resources, would like to keep it that way if possible. P.S iPad device not out where I am so I cannot test on a device yet. Would be nice for it to work on the simulator.

  • How to bind Lists of a custom view model to a dropDownList an get the selected value after POST in A

    - by user187220
    I have following problem. In my view model I defined some list properties as follows: public class BasketAndOrderSearchCriteriaViewModel { List<KeyValuePair> currencies; public ICollection<KeyValuePair> Currencies { get { if (this.currencies == null) this.currencies = new List<KeyValuePair>(); return this.currencies; } } List<KeyValuePair> deliverMethods; public ICollection<KeyValuePair> DeliveryMethods { get { if (this.deliverMethods == null) this.deliverMethods = new List<KeyValuePair>(); return this.deliverMethods; } } } This view model is embedded in another view model: public class BasketAndOrderSearchViewModel { public BasketAndOrderSearchCriteriaViewModel Criteria { [System.Diagnostics.DebuggerStepThrough] get { return this.criteria; } } } I use 2 action methods; one is for the GET and the other for POST: [HttpGet] public ActionResult Search(BasketAndOrderSearchViewModel model){...} [HttpPost] public ActionResult SubmitSearch(BasketAndOrderSearchViewModel model){...} In the view I implement the whole view model by using the EditorFor-Html Helper which does not want to automatically display DropDownLists for List properties! 1. Question: How can you let EditorFor display DropDownLists? Since I could not figure out how to display DropDownLists by using EditorFor, I used the DropDownList Html helper and filled it through the view model as follows: public IEnumerable<SelectListItem> DeliveryMethodAsSelectListItem() { List<SelectListItem> list = new List<SelectListItem>(); list.Add(new SelectListItem() { Selected = true, Text = "<Choose Delivery method>", Value = "0" }); foreach (var item in this.DeliveryMethods) { list.Add(new SelectListItem() { Selected = false, Text = item.Value, Value = item.Key }); } return list; } My 2. question: As you can see I pass my view model to the action metho with POST attribute! Is there a way to get the selected value of a DropDownList get binded to the passed view model? At the moment all the DropDownList are empty and the selected value can only be fetched by the Request.Form which I definitely want to avoid! I would greatly appreciate some ideas or tips on this!

  • Maintaining ViewModel fields with default model binding and failed validation

    - by TonE
    I have an ASP.Net MVC Controller with a 'MapColumns' action along with a corresponding ViewModel and View. I'm using the defaultModelBinder to bind a number of drop down lists to a Dictionary in the ViewModel. The view model also contains an IList field for both source and destination columns which are used to render the view. My question is what to do when validation fails on the Post call to the MapColumns action? Currently the MapColumns view is returned with the ViewModel resulting from the default binding. This contains the Dictionary values but not the two lists used to render the page. What is the best way to re-provide these to the view? I can set them explicitly after failed validation, but if obtaining these values (via GetSourceColumns() and GetDestinationColumns() in the example) carries any overhead this doesn't seem ideal. What I am looking for is a way to retain these lists when they are not bound to the model from the view. Here is some code to illustrate: public class TestViewModel { public Dictionary<string, string> ColumnMappings { get; set; } public List<string> SourceColumns; public List<string> DestinationColumns; } public class TestController : Controller { [AcceptVerbs(HttpVerbs.Get)] public ActionResult MapColumns() { var model = new TestViewModel; model.SourceColumns = GetSourceColumns(); model.DestinationColumns = GetDestinationColumns(); return View(model); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult MapColumns(TestViewModel model) { if( Validate(model) ) { // Do something with model.ColumnMappings RedirectToAction("Index"); } else { // Here model.SourceColumns and model.DestinationColumns are empty return View(model); } } } The relevant section of MapColumns.aspx: <% int columnCount = 0; foreach(string column in Model.targetColumns) {%> <tr> <td> <input type="hidden" name="ColumnMappings[<%= columnCount %>].Value" value="<%=column %>" /> <%= Html.DropDownList("ColumnMappings[" + columnCount + "].Key", Model.DestinationColumns.AsSelectItemList())%> </td> </tr> <% columnCount++; }%>
