I had a serious need for a JSON field for django. There were a couple out there, but none packaged up nicely on bitbucket/github that were usable with pip install -e.
So I took the code from David Cramer's blog, and packaged it up.
To use, just install the package, and then use the field:
from django.db import models import jsonfield class MyModel(models.Model): the_json = jsonfield.JSONField()
Now, it will validate the JSON on entry, and store it as a string in the database. When you instantiate/fetch the object, it will be turned back into a python list/dict/string.
Convert date/time objects nicely to/from ISO strings (YYYY-mm-dd HH:MM:SS TZNAME). This is actually a bit tricky, as we don't know if we are expecting a date/time object. We may parse objects as we go, but there could be some performance issues with this.
