django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'authentication.Us-CodePudding

I'm creating app with authentication. My project is dockerized. When I run the server everything works fine, except

authentication.User: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'.

But when I want to run docker-compose exec web python3 manage.py makemigrations or docker-compose exec web python3 manage.py migrate I get an error:

File "/usr/local/lib/python3.9/site-packages/django/contrib/auth/init.py", line 176, in get_user_model raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'authentication.User' that has not been installed

I've thought it points to settings.py field AUTH_USER_MODEL, but I haven't got it.

My views.py:

def signup(request):
    if request.method == "POST":
        context = {'has_error': False, 'data': request.POST}
        email = request.POST.get('email')
        username = request.POST.get('username')
        password = request.POST.get('password')

        if len(password) < 6:
            messages.add_message(request, messages.ERROR,
                                 'Password should be at least 6 characters')
            context['has_error'] = True

        if not validate_email(email):
            messages.add_message(request, messages.ERROR,
                                 'Enter a valid email address')
            context['has_error'] = True

        if not username:
            messages.add_message(request, messages.ERROR,
                                 'Username is required')
            context['has_error'] = True

        if models.User.objects.filter(username=username).exists():
            messages.add_message(request, messages.ERROR,
                                 'Username is taken, choose another one')
            context['has_error'] = True

            return render(request, 'authentication/signup.html', context)    # status=409

        if models.User.objects.filter(email=email).exists():
            messages.add_message(request, messages.ERROR,
                                 'Email is taken, choose another one')
            context['has_error'] = True

            return render(request, 'authentication/signup.html', context)   # status=409

        if context['has_error']:
            return render(request, 'authentication/signup.html', context)

        user = models.User.objects.create_user(username=username, email=email)
        user.set_password(password)
        user.save()

    return render(request, 'authentication/signup.html')

My models.py:

from django.db import models



class User(models.Model):
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,
    )

    username = models.CharField(
        max_length=200
    )
    def __str__(self):
        return self.email

My signup.html:

{% include  "_base.html" %}
{% load static %}

{% block title %}Sign Up{% endblock title %}

{% block content %}
<link rel="stylesheet" href="{% static 'css/authentication/signup.css' %}">
<div >
  <form  method="post" action="{% url 'signup' %}">
    {% csrf_token %}
    <input type="text" placeholder="Email"  name="email">
    <input type="text" placeholder="Username"  name="username">
    <input type="text" placeholder="Password"  name="password">
    <button type="submit" >Sign Up</button>
  </form>
</div>
{% endblock content %}

_base.html is just navbar. When I add AUTH_USER_MODEL to settings.py it results in same error.

CodePudding user response：

For this you should try adding an id field in the user model like so

from uuid import uuid4
id = models.UUIDField(primary_key=True, editable=False, default=uuid4)

Also in your user model add this to the class

from django.contrib.auth.models import AbstractUser
class CustomUser(AbstractUser):

I advice you also change the class name form User to CustomUser to avoid clashes with internal django backend, that will be.

From

class User(models.Model):

class CustomUser(AbstractUser):

Hope this works
