django-dbfiles 2.0.0

Custom Database Storage for Django

django-dbfiles

A fork of django-db-storage, updated for modern versions of Django (and renamed for inclusion in PyPI).

Overview

Warning: In many cases, storing files in the database is a BAD idea. Your database will easily become bloated and theperformance can degrade rapidly. See this StackExchange post for more information.

This is a custom storage backend for storing files in the database instead of the file system and is a drop-in replacement for Django's FileSystemStorage. Some benefits of this application:

• no changes needed to existing models, it just works (and if it doesn't, open a ticket!)
• django-admin is implemented and can be used to search, upload, download and manage files
• 100% code coverage with unit tests

Requirements

• Python (3.5, 3.6, 3.7, 3.8)
• Django (2.2, 3.0, 3.1)

Installation

Installation using pip:

pip install django-dbfiles

Update settings.py:

# Add 'dbfiles' to INSTALLED_APPS
INSTALLED_APPS = [
    'dbfiles',
]

# Optionally set DEFAULT_FILE_STORAGE
DEFAULT_FILE_STORAGE = 'dbfiles.storage.DBStorage'

# Choose a root url for uploaded files
MEDIA_URL = '/media/'

Update urls.py:

urlpatterns = [
    ...
    dbfiles_url(),
]

Run database migrations:

python manage.py migrate

How to Use

No modification are needed for models to work properly.

def user_directory_path(instance, filename):
    return 'user_{0}/{1}'.format(instance.user.id, filename)

class MyModel(models.Model):
    file_field1 = models.FileField()
    file_field2 = models.FileField(upload_to='uploads/%Y/%m/%d/')
    file_field3 = models.FileField(upload_to=user_directory_path)

Moving from django-db-storage?

If you are switching to this package from django-db-storage and want to keep your existing db_file table, let Django know about the app name change by running the following SQL:

UPDATE django_migrations SET app = 'dbfiles' WHERE app = 'dbstorage';
