How to delete record which used django-s3-storge

[sunjiali]

instance = Video.objects.get(id=video_id)
instance.delete()

ERROR:

/storage.py", line 123, in path
raise NotImplementedError("This backend doesn't support absolute paths.")
NotImplementedError: This backend doesn't support absolute paths.

Can I have the complete traceback, please? It looks like something in your code is expecting to be able to get a filesystem path. Since S3 doesn't support filesystem paths, that's not going to work. There's nothing in Django or django-s3-storage that mandates filesystem paths, so this is likely to be an issue in your code, or some 3rd party code. It's likely fixable, as S3 storage supports deletions just fine.

The problem is in ZHYToolsSet/video/models.py where you do os.path.isfile(instance.file.path). You cannot access file.path for django-s3-storage.

I'm not sure what this check acheives, as all S3 files are files. You should be able to simply:

from django.core.files.storage import default_storage

default_storage.delete(file.name)
