Hi,

In order to create a new record using the demo data feature, you need to provide the data in an XML format, as shown below:

<odoo>

    <record id="demo_record_1" model="new.address">

        <field name="name">Dhaka</field>

        <field name="country" ref="res.country_34"/>

    </record>

</odoo>

In the example above, we are creating a new record in the new.address model with the name "Dhaka" and setting the country field to the country with the id res.country_34, which is Bangladesh

Note that the ref attribute of the field element is used to specify the id of the record in the res.country model that you want to link to. In order to use this attribute, you will need to know the id of the record in the res.country model that you want to link to. You can find this id by checking the records in the res.country model or by using the search method of the res.country model to find the id of the record you are interested in.

Regards
