Question

Controller:

@organization.topics.find(params[:id])

How can I stub this in my controller_spec with Rspec? (@organization IS being set in my spec helper)

I’ve tried:

controller.stub_chain(:topics, :find).with("37") { mock_topic }
Topic.stub(:find).with("37") { mock_topic }

Neither of the above seem to work. Any ideas? Thanks!

If you have access to the @organization variable (you indicate that you do) then you should be able to:

@organization.stub_chain(:topics, :find).and_return(mock_topic)

I don’t believe (unless they’ve changed the API to stub_chain, but I don’t see anything of that nature in the docs) you can specify a .with(’37’) when using stub_chain. If it is absolutely necessary that you specify what variable is passed to the find method (and it rarely is), you’ll have to take the long route:

# This line is attempting to fake-out the .topics association and
# just return a mock of *whatever*, since it's just an intermediary
# step to where we really want to get to.
topics = @organizations.stub!(:topics).and_return(mock_model(Topic))
topics.stub!(:find).with('37').and_return(mock_topic)
