django-hashedfilenamestorage 2.2

Installing

The easiest way to install django-hashedfilenamestorage is to use pip:

pip install django-hashedfilenamestorage

Quick Start

In your Django settings file:

• Set DEFAULT_FILE_STORAGE to 'django_hashedfilenamestorage.storage.HashedFilenameFileSystemStorage'

This gives you hashed filenames, backed on Django’s FileSystemStorage storage class.

HashedFilenameMetaStorage

You can define a new underlying storage class by using HashedFilenameMetaStorage to wrap it:

from django.core.files.storage import get_storage_class

from django_hashedfilenamestorage.storage import HashedFilenameMetaStorage

HashedFilenameMyStorage = HashedFilenameMetaStorage(
    storage_class=get_storage_class('myapp.storage.MyStorage'),
)

Hashing algorithm

HashedFilenameMetaStorage is meant to generate duplicate filenames for files with identical contents. To do this, it reads the contents of the file and generates a SHA-1 hash of them.

Filenames have their extensions preserved, so it is possible to have duplicate contents on the filesystem, but it is important to help serve files with their proper content types.
