A generic app to provide a way to handle database binary data in django.

Introduction

This is a total rip-off of BinaryField class from Django 1.6+ sourcecode with some tweaks to make it work under Django 1.4+.

Installation

pip install django-binaryfield

Usage

Use BinaryField to bind your binary database columns on a django model. Like so:

from binaryfield import BinaryField

class ExampleModel(models.Model):

    short_data = BinaryField(max_length=10, default=b'\x08')
    data = BinaryField()

Configuration

syncdb

Django-binaryfield works out-of-the-box with existing binary database columns that are correctly mapped in your models. If you want BinaryField to work with syncdb management command there’s one setting called BINARYFIELD_HACK_ENGINES that can be used to hack Django database backend. Use it like this:

BINARYFIELD_HACK_ENGINES = (
    'django.db.backends.sqlite3',
)

It’s a list of django backends (as an “importable” strings) to mangle in order to syncdb could work properly. Did I mention that it is a hack?

Oracle issues

There are some issues with Oracle when handling parameteres in a query in Django < 1.6. You can see this link (https://github.com/django/django/commit/8aefd30379eba9aa7e5afcc69cc352adf0d23489) to see what changed in django.db.backends.oracle.base.OracleParam class regarding this feature.

There are two settings to control a fix to this issue:

  • BINARYFIELD_HACK_ORACLE_PARAM - determines whether or not apply the fix - Default: False
  • BINARYFIELD_HACK_ORACLE_PARAM_BACKENDS - an iterable of backend engines as an “importable” strings to apply the fix. - Default: [ settings.DATABASES['default']['ENGINE'] ]

TODO

  • Some more tests maybe?
  • An example view to show how to serve a file from database
