ARCHIVE NOTICE: This package has been deprecated and merged back into jsonfield.
jsonfield2 is a reusable model field that allows you to store validated JSON, automatically handling
serialization to and from the database. To use, add jsonfield.JSONField
to one of your models.
Note: django.contrib.postgres
_ now supports PostgreSQL's jsonb type, which includes extended querying
capabilities. If you're an end user of PostgreSQL and want full-featured JSON support, then it is
recommended that you use the built-in JSONField. However, jsonfield2 is still useful when your app
needs to be database-agnostic, or when the built-in JSONField's extended querying is not being leveraged.
e.g., a configuration field.
.. _django.contrib.postgres: https://docs.djangoproject.com/en/dev/ref/contrib/postgres/fields/#jsonfield
jsonfield2 aims to support all current versions of Django
_, however the explicity tested versions are:
.. _versions of Django: https://www.djangoproject.com/download/#supported-versions
.. code-block:: python
pip install jsonfield2
.. code-block:: python
from django.db import models
from jsonfield import JSONField
class MyModel(models.Model):
json = JSONField()
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:
.. code-block:: python
import collections
class MyModel(models.Model):
json = JSONField(load_kwargs={'object_pairs_hook': collections.OrderedDict})
jsonfield.JSONCharField
Subclasses models.CharField instead of models.TextField.
The test suite requires tox
and tox-venv
.
.. code-block:: shell
$ pip install tox tox-venv
To test against all supported versions of Django, install and run tox
:
.. code-block:: shell
$ tox
Or, to test just one version (for example Django 2.0 on Python 3.6):
.. code-block:: shell
$ tox -e py36-django20
.. code-block:: shell
$ pip install -U pip setuptools wheel twine
$ rm -rf dist/ build/
$ python setup.py sdist bdist_wheel
$ twine upload -r test dist/*
$ twine upload dist/*
