jsonfield 1.0.3

A reusable Django field that allows you to store validated JSON in your model.


django-jsonfield is a reusable Django field that allows you to store validated JSON in your model.

It silently takes care of serialization. To use, simply add the field to one of your models.

Python 3 & Django 1.8 supported!

Use PostgreSQL? 1.0.0 introduced a breaking change to the underlying data type, so if you were using < 1.0.0 please read before upgrading.


pip install jsonfield


from django.db import models
from jsonfield import JSONField

class MyModel(models.Model):
  json = JSONField()

Advanced Usage

By default python deserializes json into dict objects. This behavior differs from the standard json behavior because python dicts do not have ordered keys.

To overcome this limitation and keep the sort order of OrderedDict keys the deserialisation can be adjusted on model initialisation:

import collections
class MyModel(models.Model):
  json = JSONField(load_kwargs={'object_pairs_hook': collections.OrderedDict})

Other Fields


If you need to use your JSON field in an index or other constraint, you can use JSONCharField which subclasses CharField instead of TextField. You’ll also need to specify a max_length parameter if you use this field.


django-jsonfield supports Python 2.7 to Python 3.4 and Django 1.4 to 1.8

Why doesn’t it support Python 2.6?

You actually might be OK if you don’t use an OrderedDict, but there are some issues with the simplejson API that make it cumbersome to support.

Why doesn’t it support Django 1.3?

There was a bug that could only be fixed by a feature in Django 1.4. Read More if you’re interested in the details.
