STI and validates_uniqueness

Added STI and it's messed with my validates_uniqueness.
I was hoping a validate_uniqueness in the base class would validate a
field regardless of the derived classes....but it seems not to be.

Any ideas how I can enforce the below uniqueness across all inherited
validate_uniqueness_of :xyz_id , :scope => "user_id"

This is an as yet unfixed problem with Active Record

The quick fix I use is to change the following line


removing "record.class", leaving a plain find.
