Composite primary keys vs through
It looks like
destination/source_attribute_on_join_resource both expect an atom. Is it possible to reference a composite key on a join table? I am trying to set up a many_to_many relationship.6 Replies
Can you be more specific about the fields/relationships you're trying to set up?
Was looking into a
ExtOrg (external organization) and User many_to_many relationship but the ExtOrg has a composite primary key for uniqueness (platform + ext id). I can use an identity instead potentially to enforce that, but this is was sort of a "could I do this?" situationAh, yeah I don't think you reasonably can do it with many_to_many
Solution
But you can use a has_many with a filter
