Django-AWS S3, unable to delete bucket objects-CodePudding

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.

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'

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)
