Объект 'AnonymousUser' не имеет атрибута _meta во время входа

Question

У меня есть приложение в Django 1.11, и моя проблема - ошибка:

'AnonymousUser' object has no attribute '_meta'

Появляется в момент входа в систему. Ранее пользователь был создан с помощью пользовательской формы регистрации (я используюemail адрес вместо username).Пользователь создан, потому что я могу войти в панель администратора по адресу /admin/.

Ниже приведена форма входа в систему:

class LoginForm(AuthenticationForm):
    email = forms.CharField(label='Email',
                               max_length=50,
                               widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Email',
                                                             'type': 'text', 'id': 'email'}))
    password = forms.CharField(label='Password',
                               max_length=50,
                               widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Password',
                                                             'type': 'password', 'id': 'password'}))

    field_order = ['email', 'password']

    def __init__(self, *args, **kwargs):
        super(LoginForm, self).__init__(*args, **kwargs)
        self.fields.pop('username')

Answer 1

Чтобы использовать email при входе в систему, добавьте это в вашу модель USERNAME_FIELD = 'email' и попробуйте снова.
