rspec users - Dec 2010 - Rspec & Rails Nested Resources

Hey all,

I''m new to Rspec and I was just wondering what the standard way of
testing nested resources is?

I currently have a Job model which has many Correspondences.

The new action of my CorrespondencesController looks like:

  def new
    @job = Job.find params[:job_id]
    @correspondence = @job.correspondences.build
  end

And my current spec looks like:

  it "GET new" do
    @job = stub_model(Job, :to_param => "1")
    Job.should_receive(:find).and_return(@job)
    get :new, :job_id => @job.id
    assigns[:correspondence].should_not be_nil
  end

The test is currently failing with correspondence is nil, but it works
fine in the browser.

Any help here would be great, thanks.

Try assigns(:correspondence) instead. If that doesn''t work, I would
inspect the value of @job.correspondences.build (when run in the test).
It''s possible that stub_model is causing #build to return nil -- I
don''t remember the behavior off the top of my head and don''t
have a Ruby available to check. Anyway if it is nil then you''ll need to
do some more stubbing setup. stub_chain may be useful.

Thanks for your response Pat - I ended up taking the stub_chain method
which got it working.  For anyone interested this is my new test:

    it "GET new" do
      @correspondence = mock_model(Correspondence)
      @job.stub_chain(:correspondences,
:build).and_return(@correspondence)
      get :new, :job_id => @job
      assigns[:correspondence].should be_an_instance_of Correspondence
    end
