In Odoo, normally, website forms allow users to enter data, and on submission, corresponding controllers will be called, and the records will be created in the model specified in the controller.
In this blog, we will create a generic controller that can be used to create records in any model upon submission of the form.
1. First, we must create a website form with the input fields.
<template id="generic_controller_form" name="Generic Controller">

While creating the form template, we need to pass the model name as <input type="hidden" name="model" value="sale.order"/> where in value, we need to specify the model name. Also, in template definition, we can specify the field name as the name of the form fields.
2. Next, we can define a generic controller, which will be called after submitting the form
@http.route('/generic_controller', methods=['POST'], auth="public", website=True)
def menu_generic_controller_request_submit(self, **kw):
values = {}
fields = request.env['ir.model'].sudo().search([('model', '=',
kw.get('model'))]).field_id
for key, val in kw.items():
field_id = fields.sudo().filtered(lambda r: r.sudo().name == key).sudo()
if not field_id:
continue
if field_id.ttype == 'many2one':
val = int(val) if val else 0
values.update({
key: val
})
record = request.env[kw.get('model')].sudo().create(values)
return
http.request.render("generic_controller_app.generic_controller_form", {})In conclusion, the provided code demonstrates the creation of a generic controller in Odoo to handle form submissions from the website. The generic controller allows the dynamic creation of records in any specified model based on the form data submitted. This approach enhances reusability and simplifies creating new forms for different models on the Odoo website. If you want to know more about the Odoo 16 website module, refer to our previous blogs.
