Hi,

To add new countries to the country.name model, you'll need to handle the form submission through a controller. Here's an example:

XML:

<?xml version="1.0" encoding="UTF-8"?>

<odoo>

    <template id="custom_form_template" name="Custom Form">

        <t t-call="website.layout">

            <div class="container">

                <form action="/submit/custom_form" method="post">

                    <input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>

                    <div class="form-group">

                        <label for="name">Name</label>

                        <input type="text" class="form-control" id="name" name="name" required="required"/>

                    </div>

                    <div class="form-group">

                        <label for="email">Email</label>

                        <input type="email" class="form-control" id="email" name="email" required="required"/>

                    </div>

                    <div class="form-group">

                        <label for="country">Country</label>

                        <input type="text" class="form-control" id="country" name="country" required="required"/>

                    </div>

                    <button type="submit" class="btn btn-primary">Submit</button>

                </form>

            </div>

        </t>

    </template>

</odoo>

Python:

from odoo import http

from odoo.http import request

class CustomController(http.Controller):

    @http.route('/submit/custom_form', type='http', auth='public', website=True, csrf=True)

    def submit_custom_form(self, **post):

        # Check if the country already exists

        Country = request.env['country.name']

        existing_country = Country.sudo().search([('name', '=', post.get('country'))], limit=1)

        if not existing_country:

            # Create new country if it doesn't exist

            existing_country = Country.sudo().create({'name': post.get('country')})

        # Create new record in my.model

        MyModel = request.env['my.model']

        MyModel.sudo().create({

            'name': post.get('name'),

            'email': post.get('email'),

            'country_id': existing_country.id,

        })

        #Return to a template or render a response if you want

Hope it helps
