Менеджер недоступен; 'auth.User' был заменен на 'account.Account'

0 голосов
/ 05 апреля 2020

Я всегда получаю ошибку AttributeError: Менеджер не доступен; 'auth.User' был заменен на 'account.Account'

Когда я go на http://127.0.0.1: 8003 / регистрация все работает, когда я нажимаю кнопку "отправить" я получаю эту ошибку. Я пробовал разные решения, но все еще не могу понять ошибку.

Одним из возможных объяснений вашей ошибки является отступ в форме. Я думаю, что это не сделано правильно, поэтому мета-класс UserCreationForm не переопределяется. Вы можете исправить это: 

class RegistrationForm(UserCreationForm):
    email = forms.EmailField(max_length=254, help_text='Required. Add a valid email address.')

    class Meta:
        model = Account
        fields = ('email', 'username', 'password1', 'password2', )
