Hi,
When I use __table_args__ like it is in the below example following
warning appears:
Column 'person_name' on table [...] being replaced by Column [...] which
has the same key. Consider use_labels for select() statements.
I know that it can be solved by adding __table_args__ to inherited
models, but maybe there is more elegant way of doing it (and a way to
avoid pasting same line)?
why not use @declared_attr for __table_args__, so it gets created on the
fly for each subclass?
class PPLTest(db.Model):
__abstract__ = True
person_pk_id = db.Column(db.Integer, primary_key=True)
person_name = db.Column(db.String(1000))
__table_args__ = (db.UniqueConstraint(u'person_name'),
{u'mysql_engine': u'InnoDB'})
class Level1(PPLTest):
__tablename__ = u'ppl_level1'
__bind_key__ = u'test'
class Level2(PPLTest):
__tablename__ = u'ppl_level2'
__bind_key__ = u'test'
Cheers and thank you!
