Hi, I need help with a condition inside the tag, this tree has the custom model "policy_line", however, I need to disable the Delete button (trash can) when the state of another custom model (policy) is 'done'.

The way I achieved it is using attrs="{'readonly': [('state','in',['done','ok'])]}
In Odoo, disabling the delete button in a tag can be achieved by modifying the view (XML) file associated with the model. You can add an attribute "attrs" to the tag and set the "invisible" attribute on the delete button element.
attrs="{'invisible': [('id', '=', False)]}">
It's worth noting that this will make the delete button invisible if the record has no ID.
You can also use the "states" attribute instead of "attrs" and use it to control the visibility of the button based on the state of the record.
Copy code
I have the same concern, how to hide the trash button if the state is in a specific condition,
I have tried something like:
<xpath expr="//page[@name='recurring_invoice_line']//tree" position="attributes">
<attribute name="delete">0</attribute>
<attribute name="attrs">{'invisible': [('state', 'in', ['confirmed', 'done'])]}</attribute>
</xpath>
But it doesn't works.
