django-jsonfield =================== 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. Usage ----- 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. There are also a couple of other bits and bobs: Extras ------ jsonify templatetag ~~~~~~~~~~~~~~~~~~~ This allows you to convert a python data structure into JSON within a template:: {% load jsonify %} <script> var foo = {{ bar|jsonify }}; </script> History ---------- 0.8.5 ~~~~~ Allow for '{}' and '[]', and make them not appear to be None. 0.8.4 ~~~~~ Ensure the version number file is installed with the package. 0.8.3 ~~~~~ Store the version number in one place only, now. 0.8.2 ~~~~~ Oops. Packaging error prevented install from pypi. Added README.rst to manifest. 0.8.1 ~~~~~ Converting to string does nothing, as serializing a model instance with a JSONField would have a string version of that field, instead of it embedded inline. (Back to pre 0.8 behaviour). Added better querying support: (``field__contains={'key':'value','key2':'value2'}`` works.) Removed JSONTableWidget from package. 0.8 ~~~ (Many thanks to `IanLewis`_ for these features) Supports django 1.2 Supports callable and json serializable objects as default Implemented get_db_prep_value() Add tests and test runner. Removed JSONTableWidget from README. 0.7.1 ~~~~~ Don't fail when trying to install before django is installed. 0.7 ~~~ First time I tagged releases. Todo ---------- 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. .. _David Cramer's blog: http://justcramer.com/2009/04/14/cleaning-up-with-json-and-sql/ .. _IanLewis: https://bitbucket.org/IanLewis
