Dear all,
I have a question about how to automatic set the foreignkey column ?
we have two class User and Address
class User(Base):
__tablename__ = 'user'
id = Column(Integer, primary_key=True)
name = Column(String)
addresses = relationship("Address")
def __init__(self, id, name):
self.id = id
self.name = name
class Address(Base):
__tablename__ = 'address'
id = Column(Integer, primary_key=True)
user_id = Column(Integer, ForeignKey('user.id'))
def __init__(self, id, user_id):
self.id = id
self.user_id = user_id
if we create a user then add a address
User1 = User(1,"Tom")
Address1 = Address('1', None)
User1.addresses(Address1)
print User1.Address[0].user_id
after that we will get a None result ...
How to automatic assign user_id when we add address to a user?
Thanks.
