Question

我需要关联另一个模型的One2many字段上的字段，到目前为止我尝试过这样：

field_many = fields.Many2one('other.model', string="Many field")
field_related = fields.Float(string="My field", related="field_many.one2manyfield.field")

但它让我失望：

关于如何实现这一目标的任何想法？

Answer 1

但是你正在创建one2many字段中的相关字段？!!不要忘记o2m可以有多条记录，因此在尝试获取值时，odoo会感到困惑。

 o2m_field.some_field  # witch record to access [like singleton error]

但错误显示odoo在one2manyfield中找不到名为other.model的字段，它是否也是相关字段。

如果是这样我觉得odoo找不到它，因为默认情况下相关字段没有存储在数据库中。但是存储一个相关的字段是one2many字段不只是添加store=True我没有尝试过，但我们知道o2many字段在其他模型中应该有一个many2one。

因此最好通过示例来解释您想要的内容，我认为您需要使用计算字段的功能。
