AttributeError at /register Менеджер недоступен; 'auth.User' был заменен на 'account.Account'

Последние 2 дня я работаю над отладкой этого кода, но не могу найти ошибку. Я видел, что пробовал user = get_user_model(), но это не работает.

Также я добавил в настройках

AUTH_USER_MODEL = 'account.Account'

и учетная запись является зарегистрированным приложением в настройках.

Проблема исходит из вашего представления регистра, вы импортировали "from django.contrib.auth import get_user_model" и "from django.contrib.auth.models import User", которые вам нужно убрать из ваших импортируемых моделей.

# django imports 
from django.shortcuts import render , HttpResponse, redirect
from django.contrib.auth import authenticate, login
#from django.contrib.auth.models import User this where where your problem comes from
# from django.contrib.auth import get_user_model 
# now you would need to import the Account model since you are not using djangos build in User model 
from account.models import Account 


# app imports 
from .forms import RegistrationForm


# Create your views here.
# user = get_user_model() You would have to delete this or just comment it out .

# register page here

def register_view(request, *args, **kwargs):
    context = {}
    user = request.user
    if user.is_authenticated:
        return redirect("home")
    elif (request.method == 'POST'):
        print("hello")
        form = RegistrationForm(request.POST)
        print(form)
        if form.is_valid():
            form.save()
            email = form.cleaned_data.get('email').lower()
            raw_password = form.cleaned_data.get('password1')
            account = authenticate(email=email,password=raw_password)

Я также заметил, что у вас есть атрибут в файле менеджера моделей, которого нет в поле аккаунта, что, по идее, вызовет исключение ошибки атрибута, когда вы попытаетесь создать аккаунт, поэтому я предполагаю, что вы удалили атрибут профиля из менеджера, а также из вашей формы. Вот мое решение .

class MyAccountManager(BaseUserManager):
    def create_user(self, email, username, password=None):
        if not email:
            raise ValueError('Users must have an email address')
        if not username:
