Summary
I couldn't find any reference to this in the guides or docs, but association constructors for
has_one :through
associations appear to be disabled. I simply enabled them and used them in the tests and nothing broke, so I'm trying to understand why they should be disabled. I would appreciate some guidance for figuring this out. Also, if there is a good reason for this, or this change is deemed unimportant or unnecessarily risky, I think the docs should be updated to reflect thatbuild_association
andcreate_association
are not available forhas_one :through
(I'd be happy to make those changes instead if that's the case).
