title: How to Convert Json Value of Http Post Parameter to Python Dict in Django?
body: <p>I am using Django 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:</p>
  
  <pre><code>NameError: name 'true' is not defined
  </code></pre>
  
  <p>I know the json is valid, so I must be doing something wrong.</p>
  
  <p>The code is:</p>
  
  <pre><code>import json    
  def push(request):
    if request.is_secure():
      checkin_json = request.POST['checkin']
      checkin = json.load(request.POST)
  </code></pre>
  
  <p>The body of the post request is:</p>
