Django Standalone Script

Question

I am trying to access my Django (v1.10) app DB from another python script and having some trouble doing so.

This is my file and folder structure:

store
 store
   __init.py__
   settings.py
   urls.py
   wsgi.py
 store_app
   __init.py__
   admin.py
   apps.py
   models.py
   ...
 db.sqlite3
 manage.py

other_script.py

In accordance with Django’s documentations my other_script.py looks like this:

import django
from django.conf import settings

settings.configure(DEBUG=True)
django.setup()

from store.store_app.models import MyModel

But it generates a runtime error:

RunTimeError: Model class store.store_app.models.MyModel doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

I should note that my INSTALLED_APPS list contains store_app as its last element.

If instead I try to pass a config like this:

import django
from django.conf import settings
from store.store_app.apps import StoreAppConfig

settings.configure(StoreAppConfig, DEBUG=True)
django.setup()

from store.store_app.models import MyModel

I get:

AttributeError: type object 'StoreAppConfig has no attribute  'LOGGING_CONFIG'.

If I edit settings.py and add LOGGING_CONFIG=None I get another error about another missing attribute, and so on.

Any suggestions will be appreciated.

Answer 1

try to import from store_app.models – as the surrounding store folder is not a python module and should not be used when importing.

import django
from django.conf import settings

settings.configure(DEBUG=True)
django.setup()

from store_app.models import MyModel

update: i just noticed that you put that script next to your project folder – you should move it inside for this to work.

This sounds like a great use case for Django Management commands. which has the added bonus you can run it scheduled from cron, direct from the commandline, or call from inside django. This gives the script full access to the same settings and environment variables as your main project.

If you move this into an appropriate directory – using store here as an example, not a suggestion, it should work.

store 
    management 
    __init__.py
        commands
        __init__.py 
        otherscript.py

Try this

import sys, os, django
sys.path.append("/path/to/store") #here store is root folder(means parent).
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "store.settings")
django.setup()

from store_app.models import MyModel

This script you can use anywhere in your system.

I found the django-extensions package to be most useful. You can find it here

After installation and adding it to the installed apps, all you need to do is to create a directory called scripts, create a file and run it by python manage.py runscript file_name

Just remember that the file must have an entry point. That entry point is a method called run which has to be present and will run once you run python manage.py runscript file_name in the terminal

Django standalone script.

Place it in the same directory as manage.py file
Rename PROJECT_NAME to your project’s name

import os

PROJECT_NAME = 'ENTER YOUR PROJECT NAME HERE'

def main():
    # import statemts
    # from app.models import Author,Category,Book
    
    # code logic - anything you want
    

if __name__ == '__main__':
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', '%s.settings' % PROJECT_NAME)
    import django
    django.setup()
    main()

import django
from django.conf import settings
>>from store.store_app.apps import StoreAppConfig<<

This line can be deleted if "other_script.py" moves to the "store" folder & "settings.py" file inserts "other_script" name in "instaled_apps".
Don’t add "other_cript" to "instaled_apps" & change it to:

>>from store import settings
settings.configure(settings, DEBUG=True)
django.setup()<<

and in the end I think:

>>from store.store_app.models import MyModel<<

change this to:

>>from store_app.models import MyModel<<
