How to mock associated objects in Rails?

Question

I know that I can mock objects as follows:

Account.any_instance.expects(:type).returns("premium")

I remember hearing that this is considered a poor practice. I'd love to do something like

user = users(:bob)
user.account.expects(:type).returns("premium")

but this doesn't seem to mock the right object. Is there a better solution than using any_instance call on the class?

Edit: the error message that I'm getting is

not all expectations were satisfied
unsatisfied expectations:
- expected exactly once, not yet invoked: #<Account:0x5f9f8f8>.type(any_parameters)

I think it would be even better if you show the whole method and the whole test. Right now it can only be a matter of guessing. — sebkkom, Oct 08 '14 at 14:56

I am still finding my way with mocks but have you tried something like:

account = user.account
account.expects(:type).returns("premium")

It would help to have the context of your test to know which object you wanted mocked.

Just tried that, thanks. I'm getting the same error message which I'll add to my question in a bit. – sakovias Oct 08 '14 at 14:43
