Learn about the 'noupdate' attribute in Odoo for protecting data from updates during module upgrades. Ideal for configuration and custom records.
In Odoo, certain records like configurations, settings, or permissions may need to be preserved even after a module upgrade. The noupdate attribute is a powerful option for this purpose, ensuring that specific data remains untouched during updates. In this blog, we’ll explore what noupdate is, when to use it, and how to implement it in XML files for Odoo modules.
The noupdate attribute in Odoo is primarily used to prevent specific records from being updated when a module is reloaded or upgraded. By default, if a module is upgraded, all data defined in its XML files will be re-applied. With noupdate set to 1 (or True), however, records with this attribute remain unchanged after the first installation.
Common scenarios where noupdate is beneficial include:
To apply noupdate to a record, you can use the noupdate="1" attribute directly in the XML file within the <data> tag. Here’s an example:
<odoo>
<data noupdate="1">
<record id="base.default_user_permissions" model="res.groups">
<field name="name">Default Permissions</field>
<field name="category_id" ref="base.module_category_user_type"/>
</record>
</data>
</odoo>
In this example:
You can also use noupdate to protect menus, actions, and other settings. Here’s an example of protecting a menu item:
<odoo>
<data noupdate="1">
<menuitem id="menu_custom_sales" name="Custom Sales" sequence="10" parent="sales_team.menu_sales" />
</data>
</odoo>
This example prevents the custom menu item menu_custom_sales from being modified during future module updates.
Once noupdate data is set, you cannot change it directly from the XML without manual intervention, which can be done using server commands or scripts to reset specific records if needed.
The noupdate attribute is a helpful tool for data management in Odoo, allowing developers to secure certain records from unintended changes during module upgrades. By correctly applying noupdate in XML files, you can ensure your configurations and customizations remain stable across Odoo updates.
