Schema qualified tables with SQLAlchemy, SQLite and Postgresql?
- by Chris Reid
I have a Pylons project and a SQLAlchemy model that implements schema qualified tables:
class Hockey(Base):
__tablename__ = "hockey"
__table_args__ = {'schema':'winter'}
hockey_id = sa.Column(sa.types.Integer, sa.Sequence('score_id_seq', optional=True), primary_key=True)
baseball_id = sa.Column(sa.types.Integer, sa.ForeignKey('summer.baseball.baseball_id'))
This code works great with Postgresql but fails when using SQLite on table and foreign key names (due to SQLite's lack of schema support)
sqlalchemy.exc.OperationalError: (OperationalError) unknown database "winter" 'PRAGMA "winter".table_info("hockey")' ()
I'd like to continue using SQLite for dev and testing.
Is there a way of have this fail gracefully on SQLite?
