Accessing django models from a new script

Question

I have seen many answers on how to use django models outside the project. But I have no success with any. I was trying to implement this answer but I get an error. I have create

Answer 1

As the exception says there are no apps installed ergo you have no models yet.

from django.conf import settings
settings.configure(
    DATABASE_ENGINE = 'sqlite3',
    DATABASE_NAME = '/home/shivam/study/Python/automation/project/db.sqlite3',
    # ....
    INSTALLED_APPS=["myapp","myotherapp"]

)
from myapp.models import *

Answer 2

You need is importable settings.

import os
import django
os.environ["DJANGO_SETTINGS_MODULE"] = 'project.settings'
django.setup()
from .models import 

Another way call your script via the django shell:

python manage.py shell < script.py

Answer 3

The following solution work from a script located in the directory where your manage.py is located:

import os
from django.conf import settings
from django.apps import apps

conf = {
    'INSTALLED_APPS': [
        'Demo'
    ],
    'DATABASES': {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': os.path.join('.', 'db.sqlite3'),
        }
    }
}

settings.configure(**conf)
apps.populate(settings.INSTALLED_APPS)

Replace Demo with your app name and put the correct database configuration for your app. This solution worked for me on Django 1.9.
