django-database-storage

A Django 1.7/1.8 storages backend backed by your existing database.

This module provides an app named dbstorage. The app contains a single model StoredFile which is where files stored with the storage backend are put. The app also provides DatabaseStorage which you can set on your file fields.

Usage

Put the dbstorage directory in your PYTHONPATH. (I'll make this installable at another time.)

Put 'dbstorage' in your INSTALLED_APPS in your settings.py.

Add DEFAULT_FILE_STORAGE = 'dbstorage.storage.DatabaseStorage' to your settings.py.

Add to your urls.py URLconf:

url(r'^user-media', include('dbstorage.urls')),

user-media determines the URL path where media files are accessed from. You can set this to anything.

Add a File or ImageFile field to your model:

image = models.ImageField(upload_to='some-root')

some-root/ gets prefixed to all of the names of the files uploaded by this field. The names are stored in a database column.

Features

• Easily configure a media storage backend that just uses your existing database for storing and serving your media files.
• Filenames are replaced with the SHA256 hash of the file content, so you don't have to worry about leaking the name of the file when it was originally uploaded.
• MIME type autodetection (based on the file extension).
• The backend supports delete, exists, listdir, size, url, created_time, and modified_time.
• Stored files appear in the Django admin.

Dynamic image resizing

When storing images, the view method can automatically resize an image to one of a few pre-defined sizes. To use this feature, you must install pillow. Then add ?width= plus xs (768px), sm (1024 px), md (1100px), or lg (1400px) to the URL when accessing the image. The image returned in the response will have this size as a maximum dimension.
