Can someone explain why a instance variable cannot be changed through an association under rspec/factory_girl? An example is in this gist.

All tests pass except the last. All the steps pass in the console.

When you use .first and if the association is not already loaded then the object is refetched from the db each time, so the unsaved change you've made to the object is lost.

I see. No cache. So it’s effectively a no-op. That explains why update_attributes instead of the = operator works as expected.

It seems kind of pointless for a framework to allow such a thing. Boy, I’ve got a lot of old code to revisit.

Thanks for your feedback, Fred.
