I am working with odoo 16 and i have this line in a template xml:

  t t-set="payment_provider_model" t-value="request.env['payment.provider'].search([('id', '=', self.id)])[0]"/

(I know it's missing but i can't put my post correctly with them)

The objective of this line is to get me the possibility to use the differant function in my payment_provider class.

The error i get is the following :

I want to replace the self.id with something that will not raise an error but give me the actual id of my actual payment_provider
