I had a similar needs with generating diffs for tracking revision history a while back
I ended up pushing everything into a mixin class. It worked a little like this... class MutatedChecknObject(object): def generate_diff(self): insp = sqlalchemy_inspect(self) rval = {} for c in sqlalchemy_orm.class_mapper(self.__class__).mapped_table.c : h = getattr( insp.attrs , c ).history if h[1]: continue rval[c] = h[0][0] return rval -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
