Can I change Django's auth_user.username field to be 100 chars long without breaking anything?

Question

Before somebody marks this question as a duplicate of this question Can django\'s auth_user.username be varchar(75)? How could that be done? or other such questions on SO, pleas

Answer 1

For me, the code below works and is simple well.

from django.contrib.auth.models import AbstractUser

class MyUser(AbstractUser):
    ....
    # your custom fields

MyUser._meta.get_field('username').max_length = 255  # or 100

after you can run your migration
