Storage#
Custom Django file-storage backends used wherever FileField /
ImageField uploads benefit from non-default behaviour.
OverwriteStorage#
A FileSystemStorage subclass that overwrites the existing file
on the disk when a new file with the same name is uploaded – instead
of Django’s default “append _<random>” rename behaviour.
Use it on a FileField / ImageField where the upload path is
deterministic per record (e.g. staking/<pk>/<filename>) and you
want a re-upload to replace, not duplicate.
