django-randomfilenamestorage 1.1

Installing

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

pip install django-randomfilenamestorage

Quick Start

In your Django settings file:

• Set DEFAULT_FILE_STORAGE to 'django_randomfilenamestorage.storage.RandomFilenameFileSystemStorage'

• Optionally, add 'django-dbstorage' to INSTALLED_APPS

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

RandomFilenameMetaStorage

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

from django.core.files.storage import get_storage_class

from django_randomfilenamestorage.storage import RandomFilenameMetaStorage

RandomFilenameMyStorage = RandomFilenameMetaStorage(
    storage_class=get_storage_class('myapp.storage.MyStorage'),
)

RandomFilenameMetaStorage defaults to 16-character root filenames. To change the default, define settings.RANDOM_FILENAME_LENGTH to a different integer value.

To change the filename length of a wrapped storage class, pass in a length argument to RandomFilenameMetaStorage. To override it for a particular storage instance, pass in a randomfilename_length argument to its constructor.

Efficient random filename generation

RandomFilenameMetaStorage is careful about not overwriting existing files, on creation. Unfortunately, many storage classes do not throw an OSError with EEXISTS when they detect a duplicate file on _save().

If the underlying storage class accepts uniquify_names=False in its constructor, RandomFilenameMetaStorage will reduce the number of round-trips to the underlying storage class and make random filename generation more efficient.

Safe storage classes include:

• django_randomfilenamestorage.storage.SafeFileSystemStorage

• django-dbstorage.
