Flask/Python registration?

Question

Flask

How to implement the possibility of registering exclusively by specific mail?
For example, I want only those who have the mail of our organization (for example: [email protected]) to be able to register on the site. Thus cut off the left people.

Answer 1

UPD:
Problem solved
I wrote my own validator using WTForms.

Answer 2

You also have a route that processes the registration form. What's stopping you from checking it? Similarly, it is always checked if such a user already exists

Answer 3

The only true option is to take new users from the database with the mail *@mycorp.ru and send links to confirm registration there.
