mycode like:
department_table=Table('department',medadata,
Column('id',Integer,primary_key=True),
Column('name',String
(64),nullable=False,unique=True),
)
class Department(object):pass
doctor_table=Table('doctor',medadata,
Column('id',Integer,primary_key=True),
Column('name',String(32),nullable=False),
Column('department_id',Integer,ForeignKey
('department.id'),nullable=False),
)
class Doctor(object):pass
Department.mapper=mapper(Department,department_table,properties={
'doctors':relation(Doctor,backref='department'),
})
d=Doctor()
