ActiveRecord belongs_to ActiveResource

class Thing < ActiveRecord::Base   belongs_to :other_thing end

class OtherThing < ActiveResource::Base = ... end

The association here works. I can access other_thing from thing with no problems until, as usual, testing. Specifically functionally test the things_controller. The things controller is simple scaffold, however, having the association to an active resource model causes functional tests to error because they don't make the required request to the resource, dispite using the ActiveRecord::HttpMock... mechanism in the functional test.

So I have three questions really. One, is this type of relationship something that we can expect to work in rails? Or am I running off the rails here? Two, assuming that this is an acceptable use case. Using TDD, as apposed to BDD. Is there infrastructure already in rails for functionally testing this? Three, are there any other suggestions? (e.g. Stubbing @thing.other_thing, plugins that do this, etc)
