Hi All,
I'm trying to put together an Association Object mapping within a pylons
app, but am getting the following error:
OperationalError: (OperationalError) (1364, "Field 'user_id' doesn't have a
default value") 'INSERT INTO contact_duedate_user_association (contact_id,
modded) VALUES (%s, %s)' (209L, datetime.date(2012, 7, 18))
As far as I can tell I've followed the recomendations in the association
object help and am somehwta stumped as to what is causing the error. The
classes are non-declarative, and are as follows (and if the formatting
holds up the relevant bits should be in bold). Any help enormously
appreciated.
contacts_table = sa.Table('contacts', meta.metadata,
sa.Column('id', sa.types.Integer, primary_key=True),
sa.Column('project_id', sa.types.Integer, sa.ForeignKey('projects.id')),
sa.Column('client_id', sa.types.Integer, sa.ForeignKey('clients.id')),
sa.Column('firstname',sa.types.String(length=255)),
sa.Column('lastname', sa.types.String(length=255)),
sa.Column('email1', sa.types.String(length=255)),
sa.Column('email2', sa.types.String(length=255)),
