Hi all,
class A(Base):
__tablename__ = 'a'
IdA = Column('IdA', Integer, primary_key=True)
AllTheB = association_proxy("many_to_many_relation", "relation_b")
class ManyToManyRelation(
__tablename__ = 'many_to_many_relation'
IdA = Column(Integer, ForeignKey('A.IdA'), primary_key=True)
IdB = Column(Integer, ForeignKey('B.IdB'), primary_key=True)
relation_a = relationship(A, backref=backref("tarifer_dossier",
cascade="all, delete-orphan"))
relation_b = relationship(B, backref=backref("tarifer_dossier",
cascade="all, delete-orphan"))
class B(Base):
__tablename__ = 'b'
IdB = Column('IdB ', Integer, primary_key=True)
AllTheA = association_proxy("many_to_many_relation", "relation_a")
x_a is instance of A
x_b is instance of B
x_a.AllTheB returns me all the objects B relative to x_a
When i want to append new element e (instance of A)
x_a.AllTheB.append(e)
I have an error due to create mechanism of association_prox
How can i have the same (simple) behaviour of classical many to many
relationship ?
Thanks in advance
Chris
