Executing a Django Shell Command from the Command Line

Question

I would like to execute a command via Django's manage.py shell function solely from the command line

e.g.

manage.py shell -c "from myapp import models; print models.MyModel.some_calculation()"

the came way you might use the -c option with the normal Python interpreter

e.g.

python -c "print 'hello world'"

However, I don't see an equivalent -c option for manage.py shell. Is there a way to do this?

or if you want to use a file: `cat my_script.py | python manage.py shell` – Alexandre Aug 19 '14 at 16:50
I'm not sure why, but that isn't working for me. I'm forced to use `echo "$(cat my_script.py)" | python manage.py shell` instead. – christianbundy Oct 15 '15 at 02:25
Correction, indentation doesn't work with IPython, so to force the standard prompt: `... | python manage.py shell -i python` – frnhr Mar 09 '17 at 16:58

Make sure you include a `\n` at the end (with `echo -e` if necessary). – Jan Kyu Peblik Nov 10 '17 at 22:25

Not like that. But it is easy enough to write a standalone script for Django.

Links tend to expire... code example here is better. – JSmyth Dec 26 '16 at 22:29
