Django: How to delete Media Files on Digitalocean Spaces/ Amazon S3 automatically when Model instanc

Time:09-24

I have the following model defined in my Django-App

def directory_path(instance, filename):
    return 'attachments/{0}_{1}/{2}'.format(instance.date, instance.title, filename)

class Note(models.Model):
    title = models.CharField(max_length=200)
    date = models.DateField(default=datetime.date.today)
    # File will be saved to MEDIA_ROOT/attachments
    attachment = models.FileField(upload_to=directory_path)

    def __str__(self):
        return self.title

I successfully set up AWS S3/ Digitalocean Spaces to store the media file uploaded via the attachment field. However, when I delete an instance of the model, the file remains in my bucket. What do I have to do, in order to delete the file automatically in my s3 bucket, if the corresponding model intance is deleted?

Ok, so the easiest way seems to be using the third-party-package django-cleanup, see https://github.com/un1t/django-cleanup for details.

The only thing you need to do is install the app, add it at the bottom of your INSTALLED_APPS in settings.py and that's it.

When I delete a model instance, the file also gets automatically deleted in my Amazon S3/Digitalocean Spaces bucket.
