Hi,

You can do as follows,

<?xml version='1.0' encoding='UTF-8'?>
<odoo>

  <record id="test_model_id" model="ir.model" >
    <field name="info"> Main super-class for regular database-persisted Odoo models.

    Odoo models are created by inheriting from this class::

        class user(Model):
            ...

    The system will later instantiate the class once per database (on
    which the class' module is installed).
    </field>
    <field name="is_mail_thread" eval="True"/>
    <field name="is_mail_activity" eval="True"/>
    <field name="model">x_test_test</field>
    <field name="name">test.test</field>
    <field name="state">manual</field>
    <field name="transient" eval="False"/>
  </record>
  
</odoo>

Thanks
