django - Store JSON input -

i'm new django , trying content security policy reporting running on application , running issues parsing , storing json violation output. have reports posting /csp_reports/ , have built new app called security_report , added following urls.py:

url(r'^csp_report/$', 'security_report.views.secreport'), 

my models this:

import os

from django.db import models django.contrib.auth.models import user django.conf import settings  class security_report(models.model):     id=models.autofield(primary_key=true)     received=models.datetimefield(null=true)     csp_report=models.charfield()     blocked_uri=models.charfield()     column_number=models.charfield()     document_uri=models.charfield()     line_number = models.integerfield()     original_policy= models.charfield()     referrer = models.charfield()     status_code = models.integerfield()     violated_directive = models.charfield()     source_file = models.charfield()     script_sample = models.charfield()      class meta:         app_label = "events" 

and views.py not complete , not working below. stuck on how grab each individual parameter , dump database. json.loads right way this? if so, how perform save()? testing blocked_uri in view test out. keep hitting except: , getting "not saved"

from security_report.models import security_report django.utils import simplejson django.http import httpresponse, httprequest django.views.decorators.csrf import csrf_exempt, csrf_protect import json  @csrf_exempt def secreport(request):      if request.method == "post":         json_data = simplejson.loads(request.raw_post_data)         try:             data = json_data['csp-report']              blocked_uri = data['blocked-uri']             document_uri = data['document-uri']             referrer = data['referrer']             script_sample = data['script-sample']             violated_directive = data['violated-directive']             source_file = data['source-file']              b = security_report()                 b.blocked_uri = blocked_uri                 b.save()                 response = ("saved database!")           except:             response = "not saved"          return httpresponse(response)      else:         return httpresponse("not post request")
