I am using Odoo14,
How to validate user input in the website form (frontend) if the email they are filling already exists in the database?
I want to make something like this, but validate email instead of username:
Is there any code in the current frontend of Odoo modules that has the same features that I can follow?
Please, any help, source, or tutorial on how to do that will be very appreciated.
Thanks,
Tri
