Instance Method Details

#current_scoped_methods ⇒ Object

Because of some likely unintentional plumbing in the scoping/association delegation chain, current_scoped_methods returns an association proxy’s scope when called on the association collection. This means that, among other things, a named scope called on an association collection will duplicate the association collection’s SQL restriction.
