仅选择 Many2one 字段上的可用数据

Question

我创建了一个模块 asset.management.handover 和 asset.management.handover.lines 以将所有 selected 资产保存到其中。

我完成了对 Many2one 字段数据的过滤，如下所示。这是我的 .py 代码：

asset_name_id = fields.Many2one('account.asset.asset', string = "Asset", 
required = True)
serial_number_id = fields.Many2one('account.asset.asset.line', string = 
"Serial number", required = True)

我的.xml代码：

<field name="asset_name_id"/>
<field name="serial_number_id" domain = "[('serial_no_id', '=', 
asset_name_id)]"/>

如果我selectasset1，所有可用的序列号。 asset1 可以 selected。问题是：

我想，例如，如果我 select asset1 那么 select 序列号。 123 然后我想 select 另一个项目是 asset1 然后当我想 select 序列号。再次，问题来了，序列号。 123 再次可用。我想要实现的只是序列号。 123 将不再对 Many2one 可用，并且对该字段不可见。

Answer 1

一个简单的方法是检查 write 或 create 方法的值。如果序列号存在于超过 1 个产品上，则会引发异常。

另一种方法是设置动态域。例如，您可以说以下内容：

当 field1 发生变化时，我希望能够 select 仅来自 field2

上的这些记录

所以，定义一个onchange和return

return {'domain': {'field_id': [('id', 'not in', used_serials)]}}

在 used_serials 上，您将获得已使用的连续剧的 ID。
