AUTH_USER_MODEL not accept sub application.

[eltonplima@…]

In settings.py to use a custom user AUTH_USER_MODEL i have to set the format app_label.model_name.

But my custom User model is within the following structure cadastro.pessoa.Usuario and django is not accepting.

The app label is the last part of the dotted path to the app. It's the usual convention in Django.

In my INSTALLED_APPS i have: "cadastro.pessoa"

If i set AUTH_USER_MODEL="cadastro.pessoa.Usuario" the exception is raised:
ImproperlyConfigured: AUTH_USER_MODEL must be of the form 'app_label.model_name'

If i set AUTH_USER_MODEL="pessoa.Usuario" the exception is raised:
ImproperlyConfigured: AUTH_USER_MODEL refers to model 'pessoa.Usuario' that has not been installed

I suspect something's wrong with your model definition. Can you upload cadastro/pessoa/models.py?

The models.py

I've sent the wrong file.

I was receiving the following validation error when running django-admin.py validate:

ImproperlyConfigured: AUTH_USER_MODEL refers to model 'account.CustomUser' that has not been installed

The culprit was an ImportError in my account.models file.

Excuse me, but beyond a ImportError, does that mean?

Replying to eltonplima@…:

I have now discovered the true source of my problem. My models.py file was importing some custom functions from a separate file. This file was also calling the django.contrib.auth.get_user_model function. If you call that function before your custom user model has been installed, it will raise an ImproperlyConfigured exception.

The two error messages mentioned in comment#2 are both included as part of the django.contrib.auth.get_user_model function. You might want to check through your code, ensuring that your custom user models.py file is not importing anything that calls that function.

I'm running into this same issue, but I believe it is a bug in the code. Here is the relevant line:
app_label, model_name = settings.AUTH_USER_MODEL.split('.')
This is a problem, if for example, your AUTH_USER_MODEL looks like this:
AUTH_USER_MODEL = "apps.accounts.UserAccount"
split() will return a three-element list and raise an "ValueError: too many values to unpack", triggering the exception.

I've copied the function below and linked to the line on github.

​https://github.com/django/django/blob/master/django/contrib/auth/__init__.py#L117

def get_user_model():
    """
    Returns the User model that is active in this project.
    """
    from django.db.models import get_model

    try:
        app_label, model_name = settings.AUTH_USER_MODEL.split('.')
    except ValueError:
        raise ImproperlyConfigured("AUTH_USER_MODEL must be of the form 'app_label.model_name'")
    user_model = get_model(app_label, model_name)
    if user_model is None:
        raise ImproperlyConfigured("AUTH_USER_MODEL refers to model '%s' that has not been installed" % settings.AUTH_USER_MODEL)
    return user_model

No, this is *not* an error in Django; it's an error in your code.

AUTH_USER_MODEL *is not* a dotted module include path. It's an "app name.model name" definition, the same as you would get in a fixture file.

AUTH_USER_MODEL = "apps.accounts.UserAccount" is an invalid value.
