Hello, not sure if i got you right, but here is what i think.
> users_projects=Table('users_projects', metadata,
> Column('id_users', Integer, ForeignKey('users.id_users')),
> Column('id_projects', Integer, ForeignKey('projects.id_projects')),

umapper = mapper(Users, users, properties = dict(
projects = relation(Projects, secondary = users_projects),
))
> pmapper=mapper(Projects, projects, properties={

all_usuers = session.query(Users).select()
for user in all_users:
project_ids = user.fk_project.split(',')
for project_id in project_ids:
project = session.get(Projects, project_id)
user.projects.append(project)
session.flush()
> Actually, the users table has a fk_project field like 1,15,3,. Each
Now dismiss the fk_project field altogether, you do not need it with
many-to-many relationships.
