Question

消息错误：

TypeError：old_api（）至少需要3个参数（给定1个）

代码py：

@api.model
def domain_users(self):
        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=domain_users)

类py：

class Journaleline(models.Model):
    _name = 'gmat.journaleline'
    _description    =   'Detail materiel'

   rapJor_ids = fields.Many2one('gmat.rapporjournal',string='num')
   exp_P = fields.Float(string='Panne(H)',default=0)

试试这个：

# 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())

或更少打字

# 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 [])

<强>编辑：好吧，出于某种原因，我认为该方法的签名必须在旧的api尝试这个：

    # 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)

可能因为您的模型是使用osv.Model而不是model.Model
