Hi
I would do it like this (SA07):
engine = create_engine('sqlite://')
meta = MetaData(bind=engine)
Session = sessionmaker(bind=engine)
Base = declarative_base(metadata=meta)
def project_creator(tup):
return GroupProject(project=tup[0], group=tup[1])
class User(Base):
__tablename__ = 'users'
id = Column(Integer, primary_key=True)
projects = association_proxy('group_projects', 'project',
creator=project_creator)
class Group(Base):
__tablename__ = 'groups'
id = Column(Integer, primary_key=True)
class Project(Base):
__tablename__ = 'projects'
id = Column(Integer, primary_key=True)
class GroupProject(Base):
__tablename__ = 'group_projects'
_group_id = Column(Integer, ForeignKey('groups.id'),
primary_key=True)
_project_id = Column(Integer, ForeignKey('projects.id'),
primary_key=True)
_user_id = Column(Integer, ForeignKey('users.id'),
primary_key=True)
group = relationship('Group', uselist=False,
backref='group_projects')
project = relationship('Project', uselist=False,
backref='group_projects')
user = relationship('User', uselist=False,
backref='group_projects')
meta.drop_all()
meta.create_all()
s = Session()
p = Project()
g = Group()
u = User()
s.add_all([u,g,p])
u.projects.append((p, g))
s.flush()
assert u.projects[0] == p
gp = s.query(GroupProject).one()
assert gp.user == u
assert gp.group == g
assert gp.project == p
btw. your permission table has no meaning in your example.
