Hi,
Following the documentation about inheritance (Multiple Table
Inheritance, Polymorphic), I get into troubles trying to add a relation
between tables.
I just used the documentation sample and modified the engineers table
this way :
engineers = Table('engineers', metadata,
Column('person_id', Integer, ForeignKey('employees.person_id'),
primary_key=True),
Column('engineer_info', String(50)),
Column('manager_id', Integer, ForeignKey('managers.person_id')),
)
I try to add a manager to an engineer.
Even if everything is fine in the database, after a
metadata.create_all(), I can not figure out how to set the relation
between engineers and managers in my mappers.
Seems like I misunderstood something but I'm stopped.
Any help ??
Regards,
Laurent.
