Question

我已创建了一个模块asset.management.handover和asset.management.handover.lines来保存所有选定的资源。

我已完成过滤Many2one字段上的数据，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)]"/>

如果我选择asset1，则所有可用的序列号为。可以选择到asset1。问题是：

我想，例如，如果我选择asset1然后选择序列号。 123然后我想再次选择另一个属于asset1的项目，然后我想选择序列号。再次，它出现了问题，序列号。 123再次可用。我想要实现的只是序列号。 123将不再为Many2one所用，并且无法在该领域看到。

Answer 1

执行此操作的一种简单方法是在write或create方法上检查值。如果超过1个产品上存在序列，则会引发异常。

另一种方法是设置动态域。您可以说以下内容：

当field1发生变化时，我希望只能从field2

上的这些记录中进行选择

因此，定义onchange并返回

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

在used_serials上，您将拥有已使用的连续剧的ID。

仅选择Many2one字段上的可用数据
