Question

我是OpenERP的新手，我正在尝试创建一个函数来查找在会话中注册的学生百分比。到目前为止，函数compute_percentage应该找到每个会话的与会者数量我得到的错误是：AttributeError：'在browse_record中找不到字段attendee_id（attendee.attendee，3）'。我的代码中缺少什么？希望你能帮忙，我已经在这整整3天了！

    class session(osv.osv):
    _name = 'session.session'  

    def compute_percentage(self, cr, uid, ids, fields, arg, context=None):
        record_id=ids[0]
        res={record_id:0.0}
        # percentage= (attendees/seats)*100
        current_form_object=self.browse(cr, uid, ids)
        for r in current_form_object:
            other_form_object=self.pool.get("attendee.attendee").browse(cr,uid,ids)
            total= [item.attendee_id for item in other_form_object]
            res[item.id]=len(total)

        print res
        return res


    _columns = {
        'name': fields.char('Session Title', size = 50, required=True),
        'instructor_id':fields.many2one('res.partner', 'Instructor',ondelete="set null"),
        'start_date': fields.date('Start Date'),
        'duration': fields.integer('Duration'),
        'seats': fields.float('Number of Seats'),
        'attendee_ids':fields.one2many('attendee.attendee','attendee_id', 'Attendees'),
        'percentage':fields.function(compute_percentage, type='float', method=True, store=False, string='% of Headcount'),
        }

session()

class attendee(osv.osv):
    _name = 'attendee.attendee'   
    _columns = {
        'name':fields.char('Attendee Name'),
        'attendee_id':fields.many2one('res.partner','Attendee', ondelete="set null"),
        'session_id':fields.many2one('session.session', 'Session', ondelete="set null"),

        }

attendee()

以下是compute_percentage的修改代码，如果您喜欢这个，可能会有效

def compute_percentage(self, cr, uid, ids, fields, arg, context=None):
        res = {}
        total =0.0
        for r in self.browse(cr, uid, ids):
            for line in r.attendee_ids:
                total+=1
            res[item.id]=total
        print res
        return res
