Django model JSON Form Fields

django-json-field Description

django-json-field is a Django app that contains a flexible JSONField and associated form field. The model field is not only capable of serializing common JSON data types (int, float, decimal, string, time, date, datetime, etc.) but also lazily deserializing them so they can be accessed and modified as normal Python objects within Django.A form field is also provided. It will accept serialized representations: {"date": "2012-04-23T19:16:54.133", "num": "1.2399"}And also provides safe access to the datetime module and Decimal class for explicit use: {"date": datetime.datetime(2012, 4, 23, 19, 16, 54, 133000), "num": Decimal('1.2399')}While the JSON string will not be deserialized until it is accessed it can still be a performance concern. You may find it valuable to disable deserialization (JSONField(decoder=None)), or to defer loading the field altogether (i.e. MyModel.objects.all().defer('json')).django-json-field is also compatible with South.InstallationInstall from PyPI: pip install django-json-fieldInstall from GitHub: git clone git://github.com/derek-schaefer/django-json-field.git pip install -e git+git://github.com/derek-schaefer/django-json-field.git#egg=json_fieldConfigurationAdd json_field to your PYTHONPATH and INSTALLED_APPS setting:INSTALLED_APPS = ( ...
