Django-AWS S3, unable to delete bucket objects

Question

I have a Django project with MySQL storage and media objects (images) are being stored in AWS S3 simple storage.

Admin can upload images through admin panel and its being displayed in website too.

When admin delete objects, it gets deleted in MySQL but it's associated images persists in S3 bucket.

SETTINGS.PY

AWS_ACCESS_KEY_ID = ''
AWS_SECRET_ACCESS_KEY = ''
AWS_STORAGE_BUCKET_NAME = ''
AWS_S3_CUSTOM_DOMAIN = f"{AWS_STORAGE_BUCKET_NAME}.s3.me-south-1.amazonaws.com"
AWS_S3_OBJECT_PARAMETERS = {'CacheControl': 'max-age=86400'}
PUBLIC_MEDIA_LOCATION = 'media'
MEDIA_URL = f'https://{AWS_S3_CUSTOM_DOMAIN}/{PUBLIC_MEDIA_LOCATION}/'
DEFAULT_FILE_STORAGE = 'news.storage_backends.MediaStorage'

STORAGE_BACKENDS.PY

from storages.backends.s3boto3 import S3Boto3Storage
from django.conf import settings

    location = 'media'
    default_acl = 'public-read'
    file_overwrite = False

Answer 1

As Luiz said, the files persist after deleting the object. I recommend to create a signal to delete the files after the object has been deleted:

@receiver(models.signals.post_delete, sender=YourModel)
def remove_image_file_from_s3_on_delete(sender, instance, **kwargs):
    instance.your_field_name.delete(save=False)

I have used django-cleanup app, its fairly easy to setup https://pypi.org/project/django-cleanup/
