openerp 7创建方法覆盖

Question

我是新的OpenERP 7编程。我创建了一个预订模块，允许客人预订多个房间。在创建新的预订时，我希望能够将房间状态从available更改为订票。这种场景的解决方案似乎是覆盖、create、或，为openERP编写 ORM方法。

我完全不知道如何将它合并到我的代码中。下面是我代码的一部分。

class reservation(osv.osv):
    _columns = {
            'name': fields.char('Reservation No', required=True, select=True, readonly=True),
            'date_order':fields.datetime('Date Ordered', required=True, readonly=True),
            'reserved_rooms': fields.one2many('hotel.reservation.line','line_id', 'Reserved Rooms'),
            'state': fields.selection([('draft', 'Draft'),('confirmed','Confirmed'),('cancelled','Cancelled'),('done','Done')], 'State',readonly=True),
    }
reservation()

_defaults = {
        'name': lambda obj, cr, uid, context: obj.pool.get('ir.sequence').get(cr, uid,'hotel.reservation'),
        'state': lambda *a: 'draft',
        'date_order': lambda *a: time.strftime('%Y-%m-%d %H:%M:%S')
}

保留是以默认状态作为草案创建的。在我的代码中如何以及在哪里放置和使用创建或编写方法？谢谢。

试着跟着，

class reservation(osv.osv):
    _columns = {
            'name': fields.char('Reservation No', required=True, select=True, readonly=True),
            'date_order':fields.datetime('Date Ordered', required=True, readonly=True),
            'reserved_rooms': fields.one2many('hotel.reservation.line','line_id', 'Reserved Rooms'),
            'state': fields.selection([('draft', 'Draft'),('confirmed','Confirmed'),('cancelled','Cancelled'),('done','Done')], 'State',readonly=True),
     }

    _defaults = {
        'name': lambda obj, cr, uid, context: obj.pool.get('ir.sequence').get(cr, uid,'hotel.reservation'),
        'state': lambda *a: 'draft',
        'date_order': lambda *a: time.strftime('%Y-%m-%d %H:%M:%S')
     }

    def create(self, cr, uid, vals, context=None):
        ###Add your code here
        ####update status in vals
        return super(reservation,self).create(cr, uid, vals, context=context)

    def write(self, cr, uid, ids, vals, context=None):
        ###Add your code here
        ####update status in vals
        ## you will get only those fields into the vals which are updated.
        return super(reservation,self).write(cr, uid, ids, vals, context=context)
