I have found a solution, but I don't know whether this solution is
efficient:
def has_membership(i):
return db.auth_user.id.belongs([k['user_id']\
for k in db(db.auth_membership.group_id==i).select()])
grid = SQLFORM.smartgrid(db.auth_user,
user_signature=False,
linked_tables=['phone'],
fields=[db.auth_user.id, db.auth_user.first_name],
constraints=dict(auth_user=has_membership(1)),
)
