Hello,
What is the pattern for more than one relation "one to many".
I have on parent with 2 childs.
parent_table = Table('parent', metadata,
Column('parent_id', Integer, primary_key=True)
)
child1_table = Table('child1', metadata,
Column('child1_id', Integer, primary_key=True),
Column('parent_id', Integer,ForeignKey(parent_id))
child2_table = Table('child2', metadata,
Column('child1_id', Integer, primary_key=True),
Column('parent_id', Integer,ForeignKey(parent_id))
class Parent(object): pass
class Child1(object): pass
class Child2(object): pass
parent_map = mapper(Parent, parent_table,
properties={'child1':relation(Child1), 'child2':relation(Child2)})
child1_map = mapper(Child1, child1_table)
child2_map = mapper(Child2, child1_table)
This mapper coding doesn't work?
What is the right way to do that?
Thanks
