rSpec / Nested Routes / Mocks

I'm having a terrible time trying to test a nested route with rSpec. I can't seem to tell rSpec to expect the call @item.user. The following error message plagues me not matter how I try to fuss with the mock:

Spec::Mocks::MockExpectationError in 'ItemsController handling POST / items should redirect to the new course on successful save' Mock 'Item_1002' received unexpected message :user= with (#<User: 0x..fdb7bcd38 @name="User_1003">)

Any help would be greatly appreciated.

Here's my setup. Problem line indicated with ******

--routes.rb-- map.resources :users do |users|     users.resources :items end

--items_controller-- def create     @item = Item.new(params[:item])     @item.user = User.find(params[:user_id])

    respond_to do |format|       if @item.save ....etc.....

--items_controller_spec-- describe ItemsController, "create action" do

before do     @item = mock_model(Item, :to_param => "1")     @user = mock_model(User, :to_param => "1")     Item.stub!(:new).and_return(@course)     User.stub!(:find).and_return(@user)   end

  def post_with_successful_save   ***** @item.should_receive(:user)     @item.should_receive(:save).and_return(true)     post :create, :user_id => 1, :item => {}   end

it "should redirect to the new course on successful save" do     post_with_successful_save     response.should redirect_to(item_url("1")) end

The problem is that you're expecting #user when you're actually calling #user=. So your expectation should be

@item.should_receive(:user=).with(@user)

and you'll also want to stub the call in your before block. @item = mock_model(Item, :to_param => "1", :user= true)

erm, you don't need to stub it since you're setting the expectation every time in post_with_successful_save.
