I had syntax error :
@auth.requires_login()
def chmembership():
try:
if db(db.auth_group_allowed.user_id==auth.user.id)\
.select(db.auth_group_allowed.user_id,distinct=True).first().user_id==
auth.user.id:
if auth.has_membership(auth.id_group('technician'))\
or auth.has_membership(auth.id_group('coordinator'))\
or auth.has_membership(auth.id_group('admin')):
active_gr=db((db.auth_group_allowed.user_id==auth.user.id)\
& (db.auth_group_allowed.active_gr=='TRUE')
)\
.select(db.auth_group_allowed.group_id).first().group_id
membershipID=db((db.auth_membership.group_id==active_gr)\
& (db.auth_membership.user_id==auth.user.id)
)\
.select(db.auth_membership.id).first().id
rows=db(db.auth_group_allowed.user_id==auth.user.id
).select(db.auth_group_allowed.group_id)
groupSet={}
for row in rows:
authgrouprole=db(db.auth_group.id
==row.group_id).select(db.auth_group.role).first().role
groupSet[row.group_id]=authgrouprole
db.auth_membership.group_id.requires=IS_IN_SET(groupSet)
db.auth_membership.user_id.readable=\
db.auth_membership.user_id.writable=False
chmbshp =
crud.update(db.auth_membership,membershipID,deletable=False)
new_gr=db(db.auth_membership.id
==membershipID).select(db.auth_membership.group_id).first().group_id
db(db.auth_group_allowed.user_id==auth.user.id\
and
db.auth_group_allowed.active_gr=='TRUE').update(active_gr='FALSE')
db(db.auth_group_allowed.user_id==auth.user.id\
and
db.auth_group_allowed.group_id==new_gr).update(active_gr='TRUE')
return dict(chmbshp=chmbshp, active_gr=active_gr,
membershipID=membershipID, groupSet=groupSet)
except AttributeError:
pass
There is a major threat with that design... The the permission to the
auth_membership table has to be open to any user...
The only other solution I can see for now is to triggering the change on the
active_gr field of the added table auth_group_allowed...
