Registration confirmation via email?

Question

Django

There is a registration system, everything works well, it is necessary to confirm registration through a random link sent to the new user's mail.
Are there any tips or examples for this task?
there is an idea to generate random characters, make a link to it with a regular expression in the urls, then process it in the view, such as take the url randomly from the request, compare it with the urls of all users, is there a match? is_active: true.

def get_random_string(length=12,
                      allowed_chars='abcdefghijklmnopqrstuvwxyz'
                                    'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'):

Save the hash in the user session and check
Or save it in the database and check the hash and the user at the same time
