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
