Question

我有一个应用程序，用户可以预订交付并为每次交付选择交付合作伙伴。我想阻止用户在同一时间内为两个不同的交付选择相同的合作伙伴。

我想应用与更改事件相同的方法，但是在视图加载时执行此操作。

以下是选择正确域名的方法：

def delivery_partners_change(self,cr,uid,ids):
    domain=[]
    print("RECALCULATING DOMAIN")

    # the domain of the delivery partners should be all partners with can_install set that are not present in any conflicting deliveries done during the same time period. 
    for picking in self.browse(cr, uid, ids):
        print("Picking partners: "+str([x.id for x in picking.delivery_partner_ids]))
        # select partners that are in use by one of the overlapping events
        cr.execute('select id from res_partner where id not in (SELECT r.partner_id FROM stock_picking p, stock_picking_delivery_partner_rel r WHERE ((%s >= p.delivery_date_min and %s < p.delivery_date_max) or (%s <= p.delivery_date_max and %s > p.delivery_date_min)) and r.picking_id = p.id)', (picking.delivery_date_min, picking.delivery_date_min, picking.delivery_date_max, picking.delivery_date_max))
        in_use = cr.fetchall();
        domain = [("id", "in", in_use)]; 
        print("DOMAIN RETURNED = "+str(domain)); 
        return {'domain':{'delivery_partner_ids': domain}}

问题是，当用户打开视图时，他可以看到整个不受限制的域。在此onchange事件触发后，他只能获取正确的记录子集以供选择。

当用户在Web客户端中打开记录时，如何将此域应用于视图init处的字段？

Answer 1

试试这个，

在py文件中，

_columns = {

'init_onchange_call': fields.function(delivery_partners_change, string='Nothing Display', help='field at view init', multi="delivery_partners_change"),

}

在xml文件中，

<field name="init_onchange_call" invisible="1" />

根据所选值动态设置many2many字段的域
