Model in python:

I’m currently working with Odoo, and I’m quite new to the platform. I encountered an issue while trying to validate a leave request for one of my employees. The system returned the following error message:

Is it possible to define the domain force of a record rule based on a computed field on the same model? For example

When adding product to sales order:

I am working on odoo 17 community and I am trying to create api json files to connect to for example contacts module I created controller as below but when I try to test the following link on the browser I am getting error:

I have web form in a modal window where a signatory can sign and submit. After submission a 200 response is returned through a JSON request from the controller that handles the form. Now the issue is that when the 200 response is sent over to form, it is displayed on the form but the page needs contents needs to reload because once the form is signed buttons on the change. It does not give a good user experience since the page has to be reloaded manually to get the updated content.

I have installed Odoo 17 with PostgreSQL and it is working fine but when I try to create new database using Manage Databases nothing happens and the database creation form doesn’t show.

What are the tables related to the delivery of raw materials from suppliers in Odoo? Also, how can I determine if suppliers offer delivery or not? I’ve searched, but the answers are not clear.
