How to use AUTH_USER_MODEL if I just want to use the standard user model

I have seen several posts and read the documentation about how it's best practice to set AUTH_USER_MODEL in settings.py, but do not see any actual examples on how to do that. I have tried several configurations but keep getting this error:

django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'auth.User' that has not been installed

It doesn't even tell me where the error is occurring. Below are the methods I have tried:

METHOD 1:

from django.contrib.auth import get_user_model
User = get_user_model()

Then I would just reference my user like this:

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)

METHOD 2:

from django.contrib.auth.models import User

Neither worked, and I'm not sure how I would set AUTH_USER_MODEL in settings.py if I just want to use the standard user model. I'm not customizing the User object at all. I assume something like AUTH_USER_MODEL = 'django.contrib.auth.models.User' but I'm not sure.

Now I'm getting this:

AttributeError: 'str' object has no attribute '_meta'

users/forms.py

from django import forms
from django.conf import settings
from django.contrib.auth.forms import UserCreationForm
from .models import Profile


class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()

    class Meta:
        model = settings.AUTH_USER_MODEL
        fields = ['username', 'email', 'password1', 'password2']


class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()

    class Meta:
        model = settings.AUTH_USER_MODEL
        fields = ['username', 'email']

I assume something like AUTH_USER_MODEL = 'django.contrib.auth.models.User' but i'm not sure.

You refer to a model with app_name.ModelName, so in this case that is:

# settings.py

AUTH_USER_MODEL = 'auth.User'

This is also the default value, so if you want to work with Django's user model, you can simply omit the AUTH_USER_MODEL setting in the settings.py.

furthermore you need to add django.contrib.auth to the INSTALLED_APPS, so:

# settings.py

INSTALLED_APPS = [
    # …,
    'django.contrib.auth',
    # …,
]

In a ModelForm, ModelSerializer, etc. you work with get_user_model() to get a reference to the user model class:

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth import get_user_model
from .models import Profile

User = get_user_model()


class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']


class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['username', 'email']

I agree with Willem in his case. If you are going to keep this, I recommend the following.

In your Method1,

from django.contrib.auth import get_user_model
User = get_user_model()

and then in views.py, use get_user_model() instead of User. I hope it will work in your case.

You could simply do this.

Models.py

from django.contrib.auth.models import User

class Profile(models.Model):
    user = models.OneToOneField(User , on_delete=models.DO_WhatEver_You_Want)
