Read Only ByPass

This module provides a solution to the problem of the interaction between ‘readonly’ attribute and ‘on_change’ attribute when used together. It allows saving onchange modifications to readonly fields.

Behavior: add readonly fields changed by on_change methods to the values passed to write or create. If readonly_by_pass is in the context and True then it will by pass readonly fields and save its data provide by onchange method.


This module changes the behaviour of Odoo by propagating on_change modifications to readonly fields to the backend create and write methods.

To change that behavior you have to set context on ir.actions.act_window:

<record id="sale.action_quotations" model="ir.actions.act_window">
    <field name="context">{'readonly_by_pass': True}</field>

or by telling fields allowed to change:

<record id="sale.action_quotations" model="ir.actions.act_window">
    <field name="context">
        {'readonly_by_pass': ['readonly_field_1', 'readonly_field_2',]}

On one2many fields, you can also pass the context in the field definition:

<field name=”one2many_field” context=”{‘readonly_by_pass’: True}”/>
