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.
Actually, I am maiking a RabbitMQ consumer in Dango Project in the same directory as the manage.py file, i am facing the above error.
I also added
import os
import pika, sys, os, json
from matcher.views import GenerateOutput
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
These lines i got are from the stackoverflow related questions
So, you are making 2 mistakes.
First: In the Code, you have to write those os.enoviron line above to the code line where you are importing the views.py function GenerateOuput
Second: You have to import the django in the code and write the code line below
django.setup()
So the Complete Code will be :
import os
import django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
django.setup()
import pika, sys, os, json
from matcher.views import GenerateOuput
This should work.
os.environ.setdefault() only takes action when the environment variable isn't already set. That is, if DJANGO_SETTINGS_MODULE is already set in your environment, and has a different value than what you need, this would explain your issue. Try using
os.environ["DJANGO_SETTINGS_MODULE"] = "project.settings"
I have a python script within my Django project designed to run seperate from the Django app. I want to use the settings.py on my Django App how can I do that.
When I try to import
from django.conf import settings
i get
ImportError: No module named DjangoTastypie.settings
My project Structure
I am running using eclipse-> Run as python
Based on #Sardorbek Imomaliev, you should also make your DjangoTastypie in your PYTHONPATH, you can do this in your script.
import os
import sys
import django
from django.conf import settings
sys.path.append("path/to/DjangoTastypie") # path to the parent dir of DjangoTastypie
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
django.setup()
Read https://docs.djangoproject.com/en/1.9/topics/settings/#calling-django-setup-is-required-for-standalone-django-usage
So you basically will need to put this at the beginning of your script
import os
import django
from django.conf import settings
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
django.setup()
When upgraded to django 1.9 from 1.8 I got this error. I checked answers for similar questions, but I didn't think this is an issue with any 3rd party packages or apps.

I'd modified the Installed apps for 'django.contrib.auth'.
Try to add this lines to the top of your settings file:
import django
django.setup()
And if this will not help you try to remove third-party applications from your installed apps list one-by-one.
I'd a custom function written on one of my models __init__.py file. It was causing the error. When I moved this function from __init__.py it worked.
My problem was that I tried to import a Django model before calling django.setup()
This worked for me:
import django
django.setup()
from myapp.models import MyModel
The above script is in the project root folder.
In my case, the error occurred when I made python manage.py makemigrations on Django 2.0.6.
The solution was to run python manage.py runserver and see the actual error (which was just a missing environment variable).
This error may occur when you are adding an app in INSTALLED_APPS in the settings.py file but you do not have that app installed in your computer. You have two solution:
Install that app using package managers like pip in ubuntu
Or Comment out that installed app in the settings.py file
This error may also arise if you are not in your virtual environment which you may have created for your project.
I think this wasn't mentioned yet, but is a common cause for the error: The error occurs when you specify startup code that uses models. If you follow this approach and put it into your AppConfig you must not import models at the top of the file, but inside the ready() method. For example as follows:
# works as models are imported in the ready() method
from django.apps import AppConfig
class MatcherConfig(AppConfig):
name = 'matcher'
verbose_name = 'Match-Making'
def ready(self):
from matcher.background_tasks import close_timeout_games
from matcher.models import FourPlayerGame
# check if a player is not responding every 5 seconds
close_timeout_games(FourPlayerGame, repeat=5)
However, the following would be wrong:
# won't work as models are imported at the beginning
from django.apps import AppConfig
from matcher.background_tasks import close_timeout_games
from matcher.models import FourPlayerGame
class MatcherConfig(AppConfig):
name = 'matcher'
verbose_name = 'Match-Making'
def ready(self):
# check if a player is not responding every 5 seconds
close_timeout_games(FourPlayerGame, repeat=5)
For more information also see this answer.
First import and run django.setup() before importing any models
All the above answers are good but there is a simple mistake a person could do is that (In fact in my case it was).
I imported Django model from my app before calling django.setup(). so proper way is to do...
import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'first_project.settings')
import django
django.setup()
then any other import like
from faker import Faker
import random
# import models only after calling django.setup()
from first_app.models import Webpage, Topic, AccessRecord
For me, the problem came from the fact that I was importing an app in INSTALLED_APPS which was itself importing a model in its __init__.py file
I had :
settings.py
INSTALLED_APPS = [
...
'myapp',
...
]
myapp.__init__.py
from django.contrib.sites.models import Site
commenting out import models in myapp.__init__.py made it work :
# from django.contrib.sites.models import Site
Try removing the entire settings.LOGGING dictConfig and restart the server. If that works, rewrite the setting according to the v1.9 documentation.
https://docs.djangoproject.com/en/1.9/topics/logging/#examples
You may get this error if you've started normal Python shell by mistake and trying to import your Django models in that.
You should instead use python manage.py shell for that.
For me commenting out
'grappelli.dashboard',
'grappelli',
in INSTALLED_APPS worked
django.setup() in the top will not work while you are running a script explicitly.
My problem solved when I added this in the bottom of the settings file
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
import sys
if BASE_DIR not in sys.path:
sys.path.append(BASE_DIR)
os.environ['DJANGO_SETTINGS_MODULE'] = "igp_lrpe.settings"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "igp_lrpe.settings")
import django
django.setup()
I put the User import into the settings file for managing the rest call token like this
# settings.py
from django.contrib.auth.models import User
def jwt_get_username_from_payload_handler(payload):
....
JWT_AUTH = {
'JWT_PAYLOAD_GET_USERNAME_HANDLER': jwt_get_username_from_payload_handler,
'JWT_PUBLIC_KEY': PUBLIC_KEY,
'JWT_ALGORITHM': 'RS256',
'JWT_AUDIENCE': API_IDENTIFIER,
'JWT_ISSUER': JWT_ISSUER,
'JWT_AUTH_HEADER_PREFIX': 'Bearer',
}
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.IsAuthenticated',
),
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
),
}
Because at that moment, Django libs are not ready yet. Therefore, I put the import inside the function and it started to work. The function needs to be called after the server is started
I get that error when I try to run test.py(not full scripts, I don't want to use python manage.py test)
and the following method is working for me.
import os
import django
if 'env setting':
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'YourRoot.settings')
django.setup()
from django.test import TestCase
...
class SomeTest(TestCase):
def test_one(self): # <-- Now, I can run this function by PyCharm
...
def test_two(self):
...
My problem was:
django-reversion>=1.8.7,<1.9
for django 1.9.7 you should use:
django-reversion==1.10.0
I were upgraded django-cms 3.2 to 3.3, and found it by commenting apps, then uncommenting back.
Correct answer here:
https://stackoverflow.com/a/34040556/2837890
This issue is also observed for inconsistent settings.py for incorrectly writing INSTALLED_APPS, verify if you correctly included apps and separated with "," .
When I change my django version to 1.9, it don't arise the error.
pip uninstall django
pip install django==1.9
I was in trouble with such matter
my problem was because of having this piece of code in settings.py
import myapp.models
when I removed this code problem fixed
I recommend check your settings.py and remove such code
The reason I got this error appregistrynotready is That I accidentally Register User model in app.py instead of admin.py
This is how it's looked like
app.py
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from .models import User
#admin.register(User)
class UserAdmin(BaseUserAdmin):
pass
In my case one of my settings, 'CORS_ORIGIN_WHITELIST' was set in the settings.py file but was not available in my .env file. So I'll suggest that you check your settings, especially those linked to .env
As others have said this can be caused when you've not installed an app that is listed in INSTALLED_APPS.
In my case, manage.py was attempting to log the exception, which led to an attempt to render it which failed due to the app not being initialized yet. By
commenting out the except clause in manage.py the exception was displayed without special rendering, avoiding the confusing error.
# Temporarily commenting out the log statement.
#try:
execute_from_command_line(sys.argv)
#except Exception as e:
# log.error('Admin Command Error: %s', ' '.join(sys.argv), exc_info=sys.exc_info())
# raise e
I tried tons of things, but only downgrading Django to 1.8.18 fixed this issue for me:
pip install django==1.8.18
It is one of the installed apps that is failing, but I could not find which one.
I get that error when i try to run:
python manage.py makemigrations
i tried so many things and realized that i added some references to "settings.py" - "INSTALLED_APPS"
Just be sure what you write there is correct. My mistake was ".model." instead of ".app."
Corrected that mistake and it's working now.
I've run into this problem and it was rooted in asgi.py. we've loaded the below module:
from channels.auth import AuthMiddlewareStack
but we didn't use it in the ProtocolTypeRouter. apparently, we have to use
websocket or other protocols when we call the AuthMiddlewareStack module.
For others that might stumble upon this in future:
If you encounter this issue while running Python 3.8 and trying to use multiprocessing package, chances are that it is due to the sub processed are 'spawned' instead of 'forked'. This is a change with Python 3.8 on Mac OS where the default process start method is changed from 'fork' to 'spawn'.
This is a known issue with Django.
To get around it:
import multiprocessing as mp
mp.set_start_method('fork')
I faced this problem when I was trying to load a function in the init file (__init__.py) of my settings package.
The cause of this error
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet
is that, before settings were loaded, I wanted to load another module (e.g. rest_framework).
To solve this, I put functions in another module (file) in settings package
(e.g. common.py), and it solved the problem.
i faced the same issue when i used
from django.urls import reverse
Solution:
from django.urls import reverse_lazy
Late to the party, but grappelli was the reason for my error as well. I looked up the compatible version on pypi and that fixed it for me.
Try activating the virtual env.
In my case, using the git command line tool:
source scripts/activate
Solves my problem.
Got this error while trying to access model objects in apps.py:
class QuizConfig(AppConfig):
name = 'quiz'
def ready(self):
print('===============> Django just started....')
questions_by_category = Question.objects.filter(category=2) # <=== Guilty line of code.
Trying to access Question before the app has loaded the model class caused the error for me.
