Question

如何在创建记录后立即调用我的方法。到目前为止：

def _compute_stage_deadline(self, cr, uid, ids, context=None):
    for lead in self.browse(cr, uid, ids):

        stage_deadline = datetime.now() + lead.stage_id.days_for_stage
        print "Testing stage datetime: ", stage_deadline.strftime("%Y-%m-%d %H:%M:%S")
    return stage_deadline   

def create(self, cr, uid, ids, context=None):
    self._compute_stage_deadline(cr, uid, ids, context)
    return super(CRM_Lead, self).create(cr, uid, ids, context=context)

但是我在创建记录之前就调用它，所以在_compute_stage_deadline中我尝试访问该记录时出现此错误（因为该记录尚不存在）：

AttributeError: 'NoneType' object has no attribute 'stage_id'

我怎样才能绕过它并在创建后调用我的方法？

Answer 1

使用这种方法解决了这个问题：

def _compute_stage_deadline(self, cr, uid, lead, context=None):        
    stage_deadline = datetime.now() + lead.stage_id.days_for_stage
    print "Testing stage datetime: ", stage_deadline.strftime("%Y-%m-%d %H:%M:%S")
    return stage_deadline   

def create(self, cr, uid, vals, context=None):
    new_id = super(CRM_Lead, self).create(cr, uid, vals, context=context)
    lead = self.browse(cr, uid, new_id, context=context)
    self._compute_stage_deadline(cr, uid, lead, context)
    return new_id

只使用vals而不是lead：

def create(self, cr, uid, vals, context=None):
 self._compute_stage_deadline(cr, uid, vals, context)
 return super(CRM_Lead, self).create(cr, uid, vals, context=context)
