django-cleanup automatically deletes files for FileField, ImageField, and subclasses. It will delete old files when a new file is being save and it will delete files on model instance deletion.
**Warning! If you use transactions you may lose files if a transaction will rollback at the right instance. Though this outcome is reduced by our use of post_save and post_delete signals, this outcome will still occur if there are errors in signals that are handled after our signals are handled. In this case the old file will be lost and the new file will not be referenced in a model, though the new file will likely still exist on disk. If you are concerned about it you need another solution for old file deletion in your project.
This is fixed in Django 1.9+ if you are using a database that supports transactions.**
- Support for Django 1.6, 1.7, 1.8, 1.9
- Python 3 support
- Compatible with sorl-thumbnail and easy-thumbnail
django-cleanup connects post_init, post_save, and post_delete signals to special functions (these functions delete old files) for each model which app is listed in INSTALLED_APPS.
pip install django-cleanup
Add django_cleanup to settings.py :
INSTALLED_APPS = (
...
# should go after your apps in django 1.6.
# in django 1.7+ this is fixed.
'django_cleanup',
)django_cleanup should be placed after all of your apps in django 1.6. (At least after those apps which need to remove files.) If you are using django 1.7+ this is fixed with the new AppConfigs.
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.
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)tox
