Deletes old files.
django-cleanup automatically deletes old file for FileField, ImageField and subclasses, and it also deletes files on models instance deletion.
Warning! If you use transactions you may lose you files if transaction will rollback. If you are concerned about it you need other solution for old file deletion in your project.
Most django projects I’ve seen don’t use transactions and this app is designed for such projects.
- Support for Django 1.3, 1.4, 1.5, 1.6 and 1.7
- Python 3 support
How does it work?
django-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_cleanup’.
pip install django-cleanup
Add django_cleanup to settings.py
INSTALLED_APPS = ( ... 'django_cleanup', # should go after your apps )
django_cleanup should be placed after all your apps. (At least after those apps which need to remove files.)
django-cleanup sends the following signals which can be imported from django_cleanup.signals:
- cleanup_pre_delete just before a file is deleted. Passes a file keyword argument.
- cleanup_post_delete just after a file is deleted. Passes a file keyword argument.
Signals example for sorl.thumbnail
from django_cleanup.signals import cleanup_pre_delete, cleanup_post_delete def sorl_delete(**kwargs): from sorl.thumbnail import delete delete(kwargs['file']) cleanup_pre_delete.connect(sorl_delete)
