Python Shell Apps aren't loaded yet

HamzaMa96 · August 22, 2023, 7:16am

I am having the following issue when i try to write queries using python shell

from feed.models import video
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/app/feed/models.py", line 1, in <module>
    from users.models import NewUser, category
  File "/app/users/models.py", line 1, in <module>
    from django.contrib.auth.models import AbstractUser
  File "/usr/local/lib/python3.10/site-packages/django/contrib/auth/models.py", line 3, in <module>
    from django.contrib.auth.base_user import AbstractBaseUser, BaseUserManager
  File "/usr/local/lib/python3.10/site-packages/django/contrib/auth/base_user.py", line 49, in <module>
    class AbstractBaseUser(models.Model):
  File "/usr/local/lib/python3.10/site-packages/django/db/models/base.py", line 127, in __new__
    app_config = apps.get_containing_app_config(module)
  File "/usr/local/lib/python3.10/site-packages/django/apps/registry.py", line 260, in get_containing_app_config
    self.check_apps_ready()
  File "/usr/local/lib/python3.10/site-packages/django/apps/registry.py", line 137, in check_apps_ready
    settings.INSTALLED_APPS
  File "/usr/local/lib/python3.10/site-packages/django/conf/__init__.py", line 92, in __getattr__
    self._setup(name)
  File "/usr/local/lib/python3.10/site-packages/django/conf/__init__.py", line 72, in _setup
    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

then i solved this issue by writing this command in the terminal

export DJANGO_SETTINGS_MODULE=project.settings

then i got the following error

`from users.models import NewUser

This could be an issue with your Django settings, for example an app in INSTALLED_APPS that didn’t exist. Once it was removed, it resolved the exception. Apps that can’t be imported for any reason will also raise an AppRegistryNotReady exception.

HamzaMa96 · August 22, 2023, 7:45am

All apps in INSTALLED_APPS are working

KenWhitesell · August 22, 2023, 12:17pm

Three things to check:

Your current directory in the shell is the base directory of your project.
Your virtual environment for your project is active.
Are you trying to perform any ORM or database operations at the module level in your models.py file?

Also, please post your INSTALLED_APPS setting.

yanlkm · December 30, 2023, 6:22pm

Hi,
I got the same issue, there are my INSTALLED_APP and my models.py :

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    "app.apps.AppConfig",
    'corsheaders',
    'django.core'
]

from django.db import models

# Create your models here.
from django.contrib.auth.models import AbstractUser


class User(AbstractUser):
    email = models.CharField(max_length=255, unique=True)
    password = models.CharField(max_length=255)
    bio = models.TextField(blank=True)
    date_of_birth = models.DateField(null=True, blank=True)
    profile_picture = models.ImageField(upload_to='profile_pics/', null=True, blank=True)

    first_name = None
    last_name = None
    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = []

KenWhitesell · December 30, 2023, 8:06pm

django.core should not be an entry in INSTALLED_APPS.
What version of Python are you using? What version of Django?
What are the contents of your app.apps.AppConfig file?
Please post the complete traceback from the error you are receiving.

yanlkm · December 30, 2023, 8:24pm

I’m using the 3.10.6 version of Python and 5.0 of Django
My app.apps.AppConfig file content is :

class AppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'app'

Thank you for your response

This is the problem. You cannot import any models into the settings file. (This also means that you cannot use any models in your settings, but I don’t see any instances of that here.)

yanlkm · January 1, 2024, 9:07pm

Thank you very much for your help !

Yanohterry · April 12, 2024, 1:44pm

hi.
please i’m getting a similar error while running my code.

Side note: When posting code, templates, or error messages here, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted.

Please see the post above at Python Shell Apps aren't loaded yet - #4 by KenWhitesell

Yanohterry · April 12, 2024, 1:57pm

ok thanks. actually new here and also new with django.

this is my INSTALLED_APPS:

 INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.core',
    'myapp.apps.MyappConfig',
]

KenWhitesell · April 12, 2024, 2:04pm

Welcome!

That addresses one of the questions, what about the other two?

Also, why do you have django.core in your INSTALLED_APPS? It’s not an app.

You mention that you’re new to Django - have you worked your way through either the Official Django Tutorial or the Django Girls Tutorial? They’re the best places to get started.

Yanohterry · April 12, 2024, 2:07pm

I saw the django.core in the previous persons intalled_apps, so I added it hoping it could help.
here is the current directory of my shell, and it seems to me that my virtual environment is activated :
(.venv) PS C:\Users\ftefo\PycharmProjects\pythonProject1\myproject>

Yanohterry · April 12, 2024, 2:10pm

i have worked through the the Official Django Tutorial and some youtube tutorials also but i couldn’t fne any solution for the current error

KenWhitesell · April 12, 2024, 2:11pm

How are you running your project?

Yanohterry · April 12, 2024, 2:13pm

i’m running my project using the run button in pycharm
hope this answers the question

KenWhitesell · April 12, 2024, 2:14pm

What command is it issuing?
