Hello, i implemented a generic foreign key/relationship, using this example:
http://docs.sqlalchemy.org/en/latest/_modules/examples/generic_associations/discriminator_on_association.html
In the example addresses is passing in constructor:
session.add_all([
Customer(
name='customer 1',
addresses=[
Address(
street='123 anywhere street',
city="New York",
zip="10110"),
Address(
street='40 main street',
city="San Francisco",
zip="95732")
]
),
Supplier(
company_name="Ace Hammers",
addresses=[
Address(
street='2569 west elm',
city="Detroit",
zip="56785")
]
),
])
But if i try to do something like this:
_cust = Customer('name')
session.add(_cust)
session.commit()
#And After try to use "addresses"
_cust.addresses.append(Address(street='2569 west elm',city="Detroit",
zip="56785"))
#It doens't work, "addresses" is None.
Is there any way to use this without pass "addresses" in the constructor?
I'm using mysql and sqlachemy version is '1.1.15'.
