Try this:
# remove the decorator
def domain_users(self):
domain = False
if self.env.user.login=="bendjeddou.o":
domain=[('exp_P','>',0)]
else:
domain=[]
return domain
o2m_materiels = fields.One2many('gmat.journaleline',
'rapJor_ids',
string='Materiel',
domain=lambda self: self.domain_users())
or for less typing
# no need to define method
o2m_materiels = fields.One2many('gmat.journaleline',
'rapJor_ids',
string='Materiel',
domain = lambda self: self.env.user.login == "bendjedou.o" and [('exp_P','>',0)] or [])
EDITS:
ok for some reason i think the signature of the method
must be in old api try this:
# or this
# def domain_users(self, cr, uid, ids, context=None):
def domain_users(self, cr, uid, context=None):
domain = False
user = self.pool.get('res.users').browse(cr, uid, uid, context).
if user.login == "bendjeddou.o":
domain=[('exp_P','>',0)]
else:
domain=[]
return domain
o2m_materiels = fields.One2many('gmat.journaleline',
'rapJor_ids',
string='Materiel',
domain=domain_users)
May because your model is created using osv.Model not model.Model
