A non-persistent in-memory data storage backend for Django.

Project Description


An in-memory data storage backend for Django.

Compatible with Django’s storage API.

Supported Versions

Python 2.6/2.7 with Django 1.4+ Python 3.2/3.3/3.4 with Django 1.5+ Python 3.5/3.6 with Django 1.7+


In your test settings file, add

DEFAULT_FILE_STORAGE = 'inmemorystorage.InMemoryStorage'

By default, the InMemoryStorage backend is non-persistant, meaning that writes to it from one section of your code will not be present when reading from another section of your code, unless both are sharing the same instance of the storage backend.

If you need your storage to persist, you can add the following to your settings.



This library is based on django-inmemorystorage by Cody Soyland, with modifications made by Seán Hayes with support for the url method, with additional support from Tore Birkeland for writing to the file.

Wave’s modifications include packaging, and test modifications such that python test works. This version also bumps the version to 1.0.0 and renames it to dj-inmemorystorage such that it doesn’t conflict on PyPI.

The biggest difference is that this package works with Django 1.4 now (previously only 1.5+). It also supports Python 2.6/2.7 with Django 1.4+, Python 3.2/3.3/3.4 with Django 1.5+ and Python 3.5/3.6 with Django 1.7+.
