python - OpenERP 7 自定义采购订单规则

Question

我的目标是添加采购订单规则以仅显示所选用户组中当前用户创建的采购订单。我尝试应用此规则:

['|',('order_id.user_id','=',user.id),('order_id.user_id','=',False)]

但是当我尝试查看采购订单时，出现以下错误。

ValueError: Invalid field 'order_id.user_id' in leaf "<osv.ExtendedLeaf: ('order_id.user_id', '=', 14) on purchase_order (ctx: )>"

请问您有什么建议吗？

谢谢，

Answer 1

这个错误是因为在 purchase.order 对象中没有字段名 user_id.

试试这个，

['|',('order_id.validator','=',user.id),('order_id.validator','=',False)]
