Django Middleware to add request.JSON to any HTTP requests that (1) are ajax and (2) are application/json content type.

JSONMiddleware.py

from django.utils import simplejson

class JSONMiddleware(object):
    def process_request(self, request):
        request.JSON = None
        if request.is_ajax():
            if request.META.get('CONTENT_TYPE').count('application/json'):
                try:
                    request.JSON = simplejson.loads(request.body)
                except simplejson.JSONDecodeError:
                    pass
