How to make heroku automatically run compilemessages just as it runs collectstatic

Question

python manage.py compilemessages

Creates compiled translation files named like locale/en/LC_MESSAGES/django.mo from translation source files names like locale/en/LC_MESSAGES/django.po.

I would like to have the *.mo files ignored by git and not committed to the repository, as these are not source files.

Heroku already knows to perform

python manage.py collectstatic

for django projects.

How do I make it also perform compile messages?

Currently I work around the problem by adding the compilation result files (*.mo) to my repository but I'd like to know if there's a better way.

Answer 1

1. Create a file in your project root: bin/post_compile
2. Add the line ./manage.py compilemessages
3. git push origin
4. git push heroku

As you push your branch to Heroku, it should now run that command. I'm not certain whether having a custom bin/post_compile file will override the autodetection that Heroku does, so if you find that it's no longer running collectstatic, just pop that line in under your compilemessages line, but add --noinput to the line so that the management command doesn't prompt you to type "Yes" to confirm you want to overwrite existing files.
