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

Project description

django-jsonfield

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.

Install

pip install jsonfield

Usage

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

jsonfield.JSONCharField

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.
