Artist.first.medias returns all medias. Media is an STI. Media can be video or painting.
How do I return all paintings of an artist? Only paintings, not videos? In my Artist model, I tried putting: has_many :paintings, :through => :medias In console, I do: Artist.first.paintings.all And I get: ActiveRecord::HasManyThroughSourceAssociationNotFoundError: Could not find the source association(s) :painting or :paintings in model Media. Try 'has_many :paintings, :through => :medias, :source => <name>'. Is it one of :artist? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
