name_search方法的使用

转自:http://blog.csdn.net/littlebo01/article/details/22075573

在many2one类型中，页面下拉时会首先触发name_search方法，参数这里就不解释了，

优化前：

def name_search(self, cr, user, name, args=None, operator='ilike', context=None, limit=100):
            if not args:
                args = []
            if context.has_key('current_id'):
                current_pid = context['current_id']
                cr.execute('select id from stock_picking_apply_move')
                ids_get = cr.fetchall()
                ids = []
                if not ids_get:
                    pass
                else:
                    for id in ids_get:
                        ids.append(id[  0])
                moves_obj = self.pool.get('stock.picking.apply.move').browse(cr, user, ids, context=context)
                pro_ids = []
                for move in moves_obj:
                    if move.jp_apply_picking_id.id==current_pid:
                        pro_ids.append(move.product_id.id)
                return self.name_get(cr, user, pro_ids, context=context)
            else:
                #super(jp_product_product,self).name_search(cr, user, name, args=args, operator=operator, context=context, limit=limit)
                tenant_id = context['tenant_id']
                if not tenant_id:
                    raise except_osv(_('warning'),_('必须选择租户'))
                if context.has_key('tenant_id'):
                    cr.execute('select id from product_product where tenant_id = %s',(tenant_id,))
                    ids_get = cr.fetchall()
                    ids = []
                    if not ids_get:
                        return {}
                    else:
                        for id in ids_get:
                            ids.append(id[  0])
                        return self.name_get(cr, user, ids, context=context)
                else:
                    raise except_osv(_('warning'),_('必须选择租户'))  

        def name_get(self, cr, uid, ids, context=None):
            """Get Product In Picking"""
            if not len(ids):
                return []
            res = [ (r['id'], r['name'] and r['name']
                                          or r['name'] )
                    for r in self.read(cr, uid, ids, ['name', 'id'],
                                       context=context) ]
            return res

优化后：

def name_search(self, cr, user, name, args=None, operator='ilike', context=None, limit=100):
        if context.has_key('current_id'):
            current_pid = context['current_id']  

            ids = []
            apply_obj = self.pool.get('stock.picking.apply').browse(cr, user, current_pid, context=context)
            for move_line in apply_obj.move_lines_apply:
                prod = move_line.product_id
                ids.append(move_line.product_id.id)  

            return self.name_get( cr, user, ids, context=None)  

        elif context.has_key('tenant_id'):
            if context['tenant_id'] == False:
                raise except_osv(_('提示：'),_('请选择租户'))
            args = [('tenant_id', '=', context['tenant_id'])]  

        return super(jp_product_product,self).name_search(cr, user, name, args=args, operator=operator, context=context, limit=limit)

有没有发现，差异很大呢。

注意：使用了name_search方法，在xml中加的domain可能会不起作用
