In example there are two classes
class User(object):
pass
class Address(object):
pass
but I have only one
It it possible to make join like
"Service 2 marked table B can contain Service 1, 3 marked table A in
the same table"
[service]
id table name code
1 A service1 9843904
2 B serivce2 4394343
3 A service3 6632901
[service_btype]
service_b_id service_a_id
2 1
2 3
