Try using a Django management command instead.

# myproject/myapp/management/commands/my_command.py

from django.core.management.base import NoArgsCommand
from django.template import Template, Context
from django.conf import settings

class Command(NoArgsCommand):
    def handle_noargs(self, **options):
        t=Template("My name is {myname}.")
        c=Context({"myname":"John"})
        f = open('write_test.txt', 'w')
        f.write(t.render(c))
        f.close

And then (if you follow the docs) you will be able to execute the command in the following fashion:

python manage.py my_command

This method is deprecated in Django 1.4. Use django.conf.settings.configure() instead
(see @adiew’s answer for example code).

Old method follows.

Put this at the beginning of your script

from django.core.management import setup_environ
import settings
setup_environ(settings)

This is really what the manage.py does behind the scene. To see it view the Django source in django/core/management/__init__.py. After executing these lines everything should be just like in ./manage.py shell.

Try put these two lines at the beginning of your script:

from django.conf import settings
settings.configure() # check django source for more detail

# now you can import other django modules
from django.template import Template, Context

UPDATE: From another post.

./manage.py shell < myscript.py

To import Django’s settings use:

from django.conf import settings

Instead of manually adding things to your python script, or having to fit in the management command format, in case this is not something that needs to stay around long, you can get all the benefits of the Django environment by running your script with ./manage.py runscript <myscript.py>

… but if your script is in your project folder, then you can just add this line to the top of the python script: import os; os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

Saw in https://stackoverflow.com/a/24456404/4200284 a good solution for Django >= 1.7 and in case someone uses django-configurations this worked for me:

import sys, os, django

sys.path.append('/path/to/project')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.local") # path to config

## if using django-configurations
os.environ.setdefault("DJANGO_CONFIGURATION", "Local")
from configurations import importer
importer.install()

django.setup() ## apparently important for django 1.7

from foo.models import Bar

print Bar.objects.all()

Here is yet another variant: I wrote and often use a management command “run” which has the advantage that scripts can see their command-line parameters:
