Hi all, Using sqlalchemy 0.7.2 I created a couple of mixin classes (say Mixin) to share columns declarations between model classes (say A and B). Sometimes I have to create instances of type B initialized with the values of an existing object of type A for the columns declared by Mixin. I'd like to make this code extensible with respect to the columns declared in Mixin, i.e. adding new columns to Mixin should require updating this code. Is there a way to find the names of column properties contributed by a Mixin? (I tried with checking Mixin.__dict__ for items of type sqlalchemy.schema.Column, but this doesn't give foreign keys declared via @declared_attr) best regards robert
