While building a DRF package, unable to import dependencies from Django packages

[jeetpatel9]

I am writing a package for reusable APIs and want to later publish it on PyPI. I have already published a basic python package which has a helloworld() to understand how this would work.

I have a set of APIs in my DRF app. I moved that app in a my packaging directory of setup.py. Also, I have added external dependencies to the setup.py.

setup(
    name="django_restframework",
    version="0.0.1",
    description="Some description",
    long_description=get_doc(),
    long_description_content_type="text/markdown",
    url="https://github.com/some/path.git",
    py_modules=['manager', 'serizalizer', 'models',
                'services', 'tests', 'urls', 'views'],
    package_dir={'': 'django_restframework_2fa'},
    author='Jeet Patel',
    author_email='********@gmail.com',
    python_requires='>=3.7',
    include_package_data=True,
    zip_safe=False,
    packages=find_packages(
        exclude=['tests', 'tests.*', 'licenses', 'requirements']),
    classifiers=[
        "Environment :: Web Environment",
        "Programming Language :: Python",
        "Programming Language :: Python :: 3",
        "Programming Language :: Python :: 3.6",
        "Programming Language :: Python :: 3.7",
        "Framework :: Django",
        "Framework :: Django :: 3.1",
        "Framework :: Django :: 3.2",

        'License :: OSI Approved :: MIT License',
        'Operating System :: OS Independent',
        'Topic :: Internet :: WWW/HTTP',
    ],
    install_requires=[
        "djangorestframework",
        "django",
        "djangorestframework-simplejwt",
        "pyjwt",
        "twilio==6.55.0",
        "djangorestframework-simplejwt==4.6.0",
        "django-phonenumber-field==5.2.0",
        "phonenumbers==8.12.24",

    ],
    extra_requires={
        "dev": [
            "pytest>=3.7",
            "twine 3.4.1",
        ]
    }
)

Now, I created settings.py in the the app directory and it has this -

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'corsheaders',
    'phonenumber_field',
    'rest_framework',
    'django_restframework_2fa',
]

SECRET_KEY = '***'

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_simplejwt.authentication.JWTTokenUserAuthentication',
    ),
    'TEST_REQUEST_DEFAULT_FORMAT': 'json'
}


# set auth model for the application.
AUTH_USER_MODEL = 'django_restframework_2fa.User'

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'
DEFAULT_AUTO_FIELD = 'django.db.models.AutoField'

# Phone Number config.
PHONENUMBER_DB_FORMAT = 'INTERNATIONAL'
PHONENUMBER_DEFAULT_REGION = 'IN'


SIMPLE_JWT = {
    'ACCESS_TOKEN_LIFETIME': datetime.timedelta(minutes=30),
    'REFRESH_TOKEN_LIFETIME': datetime.timedelta(days=1),
}


TWILIO_SID = '****'
TWILIO_AUTH_TOKEN = '***'
TWILIO_SERVICE_ID = '***'

Then I installed those dependencies using cmd pip install -e . and then created a distribution package using python setup.py bdist_wheel.

In the app module imports like from django.contrib.auth import get_user_model from django.conf import settings are also not work.

However, when I started python shell and tried to import classes from the app modules it returned me an error AppRegisteryNotReady-

Here is the complete traceback -

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/jeetpatel/Desktop/django-restframework-2fa/django_restframework_2fa/models.py", line 4, in <module>
    from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin
  File "/Users/jeetpatel/Desktop/environments/lib/python3.9/site-packages/django/contrib/auth/models.py", line 3, in <module>
    from django.contrib.auth.base_user import AbstractBaseUser, BaseUserManager
  File "/Users/jeetpatel/Desktop/environments/lib/python3.9/site-packages/django/contrib/auth/base_user.py", line 48, in <module>
    class AbstractBaseUser(models.Model):
  File "/Users/jeetpatel/Desktop/environments/lib/python3.9/site-packages/django/db/models/base.py", line 108, in __new__
    app_config = apps.get_containing_app_config(module)
  File "/Users/jeetpatel/Desktop/environments/lib/python3.9/site-packages/django/apps/registry.py", line 253, in get_containing_app_config
    self.check_apps_ready()
  File "/Users/jeetpatel/Desktop/environments/lib/python3.9/site-packages/django/apps/registry.py", line 136, in check_apps_ready
    raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

I was expecting imports to work as the dependencies related to those are already installed.

Where am I going wrong.

Also, the link to the tutorial or an article on how to create a DRF package would also help.
