Mocking an AR: ActiveRecord::AssociationTypeMismatch error

Testing RSpec
1

I have a Premise model with lots of validations and somewhat complex
callbacks. I’ve already written tests for those (and they pass).

I also have a MeteredService model for which premise :has_many
metered_services and (of course) metered_service :belongs_to premise.

Testing MeteredService doesn’t require a real Premise – all it needs is
a premise_id – so for my MeteredService tests I tried a simple mock
like:

premise = double("premise", :id => 1)

But this fails with:

Failure/Error: MeteredService.create(:premise => @premise)
ActiveRecord::AssociationTypeMismatch:
Premise(#2202729700) expected, got RSpec::Mocks::Mock(#2154067120)

I really don’t want to create a real Premise object unless there’s a
way to inhibit all the validations and callbacks. (FWIW, I use
FactoryGirl for other test, but it evidently triggers validations and
callbacks just like an ordinary .create())

What are my options?
