django-transactional-cleanup automatically deletes old file for FileField, ImageField and subclasses, and it also deletes files on models instance deletion. This app is based on django-cleanup.
Warning: It depends on django-transaction-hooks app and you need to configure your database backend to use a django-transactional-hooks backend or any that use the django-transactional-hooks backend mixin. See the documentation here: https://django-transaction-hooks.readthedocs.org/ .
django-transactional-cleanup connects pre_save and post_delete signals to special functions(these functions delete old files) for each model which app is listed in INSTALLED_APPS above than 'django_transactional_cleanup'.
pip install django-transactional-cleanup
Add django_transactional_cleanup to settings.py
INSTALLED_APPS = (
...
'django_transactional_cleanup', # should go after your apps
)
django_transactional_cleanup should be placed after all your apps. (At least after those apps which need to remove files.)
