How to Convert Json Value of Http Post Parameter to Python Dict in Django?

I am using Djan开发者_Go百科go to receive and process push notifications from the foursquare real-time api. Each checkin is pushed as a POST request to my server containing a single parameter named checkin. I am trying to grab the value of the checkin parameter and convert it to a python dict. However, calling json.loads always results in the following error:

NameError: name 'true' is not defined

I know the json is valid, so I must be doing something wrong.

The code is:

import json    
def push(request):
  if request.is_secure():
    checkin_json = request.POST['checkin']
    checkin = json.load(request.POST)

The body of the post request is:

"checkin = 
{
"id": "4e6fe1404b90c00032eeac34",
"createdAt": 1315955008,

}
}"

Try json.loads(checkin_json) instead of json.load(request.POST). Notice the extra 's'.

---

change checkin = json.load(request.POST) to checkin = json.loads(checkin_json)

---

On python, boolean values are Capitalized (first letter is uppercase): True/False.

Check this.

EDIT: Pay attentiot at this lines:

"primary": true
    }
],
"verified": true,

Both "true" values are lowercase and need to be capitalized
