如何写入many2many字段并在UI中显示？

如何解决如何写入many2many字段并在UI中显示？

merged_beneficiary_ids = fields.Many2many(
        'openg2p.beneficiary','merged_beneficiary_rel','retained_id','merged_id',string="Merged Duplicates",index=True,context={'active_test': False},help="Duplicate records that have been merged with this."
             " Primary function is to allow to reference of merged records "
    )

我想写入这个many2many字段并在odoo UI中显示merged_id的一些特定字段（可能是名字或姓氏）。我拥有的数据是受益人记录，id将被保留并合并id。

解决方法

当您想显示特定字段时，这适用于 x2many 字段： 先把标签字段为×2many字段加上起始标签：

<field name="x2many_field_name>
</field>

现在您在字段内添加树标记以为此特定字段制作特定列表：

<field name="x2many_field_name>
    <tree>
        <!-- here you make a list view for x2many field's model so it's as you're inside the x2many field's model -->
         <!-- specific fields you want to show here -->
    </tree>
</field>

最终代码如下：

 <field name="merged_beneficiary_ids">
     <tree>
         <!-- your fields here -->
         <field name="firstname" />
     </tree>
 </field>

要将现有记录添加到集合中：

self.write({'merged_beneficiary_ids' : (4,id,0)
})

请查看有关 x2many 字段操作的文档，因为 Odoo 以特殊方式处理它。 https://www.odoo.com/documentation/14.0/developer/reference/orm.html#odoo.models.Model.write
