rspec problem stubbing with ActiveRecord assiociations

Hi everybody,

my name is Olaf, I''m living in Berlin and this is my first post.
I''m
quite new to rpsec, so please forgive my Newbieness! I''ve a problem
stubbing a simple update action in a controller. I use a little hack
to stub AR associations. So I added to my rspec_helper.rb the
following code:

--------

# Stubbing Associations
module Spec
  module Mocks
    module Methods
      def stub_association!(association_name, methods_to_be_stubbed {})
        mock_association Spec::Mocks::Mock.new(association_name.to_s)
        methods_to_be_stubbed.each do |method, return_value|
          mock_association.stub!(method).and_return(return_value)
        end
        self.stub!(association_name).and_return(mock_association)
      end
    end
  end
end

--------

No I want to test the following action in my controller:

--------

  def update
    @profilecategory = @user.profilecategories.find(params[:id])
    respond_to do |format|
      if @profilecategory.update_attributes(params[:profilecategory])
        flash[:notice] = _(''Category was successfully
updated.'')
        format.html { render :action => "index" }
        format.js
      else
        format.html { render :action => "edit" }
        format.js
      end
    end
  end

-------

This is my Rspce code for doing so:

-------
describe ProfilecategoriesController do
  before(:each) do
    @current_user = mock_model(User)
    @profilecategory = mock_model(Profilecategory)
    @current_user.stub_association!(:profilecategories, :build =>
@profilecategory,
      :find => @profilecategory)
    @user = @current_user
    controller.stub!(:current_user).and_return(@current_user)
  end

describe "handling PUT /profilecategories/3 with successfull save" do
    it_should_behave_like "the user is logged in"

    before(:each) do
      @profilecategory.stub!(:update_attributes).and_return(true)
    end

    def do_put
      put :update, :id => ''3'', :profilecategory =>
{:name => ''new
name''}
    end

    it "should be successfull" do
      do_put
      response.should be_success
    end

    it "should find the object" do
 
@user.profilecategories.should_receive(:find).with(''3'').and_return(@profilecategory)
      do_put
    end

    it "should call the update_attributes function" do
      @profilecategory.should_receive(:uptdate_attributes).with({:name
=> ''new name''}).and_return(true)
      do_put
    end
  end
end

-------

When I run the rspec file, I always get this error:

------

should call the update_attributes function
Mock ''Profilecategory_1034'' expected :uptdate_attributes with
({:name=>"new name"}) once, but received it 0 times

------

I don''t understand this. My Associations seem to work and when calling
the update action in the browser, everything works fine. I guess it
has something to do with AR not caching the associations. But I don''t
know how to solve this problem.

I also thought about this approach, but didn''t get it to work
properly:

------
@profilecategories = mock(Profilecategory)
@user.stub!(:profilecategories).and_return(@profilecategories)
-----

It would be great, if anyone could help me with that! I don''t know,
what to do!

Best regards,
Olaf

Re: rspec problem stubbing with ActiveRecord assiociations

Sorry for the double post!

Just a quick update on the problem:

What makes it even stranger:

When I add this to my action:
--------
]@profilecategory.testfunct([])
--------
And then test the function call in the rspec like this:
--------
describe "with successfull save" do
      before(:each) do
        @profilecategory.stub!(:update_attributes).and_return(true)
        @profilecategory.stub!(:testfunct).and_return(true)
      end

      it "should be successfull" do
        do_put
        response.should be_success
      end

      it "should find the object" do
 
@user.profilecategories.should_receive(:find).with(''3'').and_return(@profilecategory)
        do_put
      end

      it "should call the update_attributes function" do
 
@profilecategory.should_receive(:uptdate_attributes).with({:name =>
''new name''}).and_return(true)
        do_put
      end

      it "should call a test function" do
        @profilecategory.should_receive(:testfunct)
        do_put
      end
    end
---------
Everything works fine and it recognizes the testfunct call. So it just
doesn''t recognize the update_attributes call.

Any ideas?

Re: rspec problem stubbing with ActiveRecord assiociations

I solved the problem by using save and partial updates in rails 2.1
instead of update_attributes. Very strange thing!

Um, you spelt '':update_attributes'' wrong?
