If I define an association (in my case a polymorphic one) in an STI
parent class, and try to eagerly load it in a subclass, I get the
following error:
ActiveRecord::ConfigurationError: Association name ‘myassoc’ was not
found; perhaps you misspelled it?
If I redefine the same association again in the STI subclass, it
works.
Is this a bug or what?
