У меня есть приложение в django 1.11, и я создал логин по электронной почте вместо имени пользователя.Чтобы войти в систему с помощью формы входа, мне пришлось переписать класс AuthenticationForm
и вставить электронное письмо вместо имени пользователя.
forms.py
UserModel = get_user_model()
Здесь я перезаписал AuthenticationForm
Класс и изменить имя пользователя на электронную почту.

username/password logins.

label=_("Email address"),

widget=forms.PasswordInput,

"fields may be case-sensitive."

Это так, как сейчас, это нормально?Можно ли сделать это короче / лучше?
