Thanks Fran... now I think it's more clear in my head...
again, I post my code with the right names...
here's my applications.sefom.modules.validators.py (yes , my
application name is 'sefom') :
from gluon.validators import *
class IS_NOT_IN_DB_DDOWN_UIM(object):
def __init__(self,*a,**b):
IS_IN_DB.__init__(self,*a,**b)
def __call__(self,value):
e=IS_IN_DB.__call__(self,value)
if e[1]:return e
e=IS_NOT_IN_DB(db
(db.u_implantee.unit_id==request.vars.unit_id),'u_implantee.zd_id')
(value)
return e
here's the code I put in my model db.py:
from applications.sefom.modules.validators import *
db.define_table('zonedef',
SQLField('nom'))
db.zonedef.nom.requires=[IS_NOT_EMPTY(error_message='ne peut être
vide!'),IS_NOT_IN_DB(db,'zonedef.nom')]
db.define_table('u_nommee',
SQLField('nom'),
SQLField('description',length=128))
# table des unités
db.define_table('u_implantee',
SQLField('unit_id',db.u_nommee),
SQLField('zd_id',db.zonedef"),
SQLField('nb_u','double'))
db.u_implantee.zd_id.requires=IS_IN_DB(db,'zonedef.id','%(nom)s')
db.u_implantee.unit_id.requires=IS_IN_DB(db,'u_nommee.id','%(nom)s : %
(description)s')
db.u_implantee.zd_id.requires=IS_NOT_IN_DB_DDOWN_UIM(db,'zonedef.id','%
(nom)s')
and here's the error I get :
File "applications/sefom/modules/validators.py", line 27, in __init__
IS_IN_DB.__init__(self,*a,**b)
TypeError: unbound method __init__() must be called with IS_IN_DB
instance as first argument (got IS_NOT_IN_DB_DDOWN_UIM instance
instead)
I'm using postgreSQL and I created a multi-column constraint on
(zd_id,unit_id) for 'u_implantee' table. So the duet can't be present
twice.
Is there another solution ?
Thanks a lot for your help.
