如果一个字段填充其他字段在xml中是必需的?

Question

<field name="warranty_from" attrs = "{'readonly': [('state','in',['approved'])]}"/>
<field name="expiry_date" attrs = "{'readonly': [('state','in',['approved'])]}"/>

如何在xml中编写一个条件，如果一个(waranty_from)字段被填充，那么expiry_date不应该是空的?

Answer 1

您的XML可以如下:

<field name="warranty_from" attrs = "{'readonly': [('state','in',['approved'])]}"/>
<field name="expiry_date" attrs = "{'required': [('warranty_from','!=', False)]}"/>
