How to run scripts outside django

django-script.py

# coding: utf-8
import os
import django

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
django.setup()

# write your code here

I was running
python ./manage.py shell < myscrip.py

If i run it just like
python myscrip.py

It gives me error
import(name)
ImportError: No module named project.settings

My script:

#!/home/django/Env/holter_dev/bin/python2

coding: utf-8

import os
import django

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
django.setup()

if name == "main":
print 'LOOK'#!/home/django/Env/project/bin/python2

coding: utf-8

import os
import django

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
django.setup()

if name == "main":
print 'LOOK'

This code helped me to run script with main block

import os, sys

proj_path = "/path/to/my/project/"

This is so Django knows where to find stuff.

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
sys.path.append(proj_path)

This is so my local_settings.py gets loaded.

os.chdir(proj_path)

This is so models get loaded.

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

at the root of your project create scripts/yourscript.py so that you have manage.py and scripts directoroy as siblings.
export DJANGO_SETTINGS_MODULE=your.settings
run ./manage.py runscript yourscript
this will load django environment and run your script within that.
you may consider putting the command in a Makefile to make it easier to manage for others.

Edit: Note that you need a run() function inside your script
Edit2:

as @geekyarthurs mentioned the above requires the RunScript extension https://django-extensions.readthedocs.io/en/latest/runscript.html

The way which I've found since then which doesn't require an extension is to create a script under:

<django project>/<a django app>/management/commands/yourcommand.py

make a class derived from BaseCommand and implement def handle(self, *args, **options):

For anyone who's trying to use the above mentioned @nurettin you need to install django-extensions.
