如何在xml中更改字段要求？

Question

我有一个字段＆＃34; required＆＃34; = True，我希望以继承的形式更改为False。

      <field name="customer_id" position="replace">
               <attribute name="required">False</attribute>
      </field>

但我得到了：

      Integrity Error
The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set

[object with reference: customer_id - customer.id]

Answer 1

  

在ODOO中，如果字段设置为required = python文件中的True，则为   无法将其标记为必需= xml文件中的Flase。

使其非必要：

使用required = False重新声明python文件中的字段。 因为一旦一个字段在python中声明required=True，也会在数据库中设置为必需，但在xml的情况下则不一样。

希望它对您的情况有所帮助。

Answer 2

In xml file you can do  it: 
<field name="customer_id" position="attribute">
   <attribute name="required">False</attribute>
</field>

and in python code it is also possible to make required false.
If you want field required False in view add required=False in xml.
if you want field required False which is required True in parent (in database constrains) simply override it in inherited class.
