- calling corresponding_column with keys_ok matches columns on name, not key, since
the name is meaningful with regards to SQL relationships, the key is not - adjustments to the recent polymorphic relationship refactorings, specifically for many-to-one relationships to polymorphic unions that did not contain the base table [ticket:439]. the lazy/eager clause adaption to the selectable will match up on straight column names (i.e. its a more liberal policy) - lazy loader will not attempt to adapt the clause to the selectable if loads_polymorphic is not enabled, since the more liberal policy of adapting columns fails for more elaborate join conditions - will have to see if ppl want to do complex joins with polymorphic relations... may have to add "polymorphic_primaryjoin" in that case as a last resort (would make working around these issues a snap, tho...)
