Django Test Client squishes nested JSON

Question

I'm having a problem very similar to Django's Querydict bizarre behavior: bunches POST dictionary into a single key and Unit testing Django JSON View. However, none of the questions/responses in these threads really point at the specify problem I'm having. I'm trying to use Django's test client to send a request with a nested JSON object (what I have works well with JSON objects with non-JSON values).

Attempt #1: Here's my initial code:

    response = c.post('/verifyNewMobileUser/', 
        {'phoneNumber': user.get_profile().phone_number,
         'pinNumber': user.get_profile().pin,
         'deviceInfo': {'deviceID': '68753A44-4D6F-1226-9C60-0050E4C00067', 'deviceType': 'I'}})

As you can see, I have a nested JSON object within my request data. However, this is what request.POST looks like:

<QueryDict: {u'phoneNumber': [u'+15551234567'], u'pinNumber': [u'4171'], u'deviceInfo': [u'deviceType', u'deviceID']}>

Attempt #2: Then I tried, adding on the content-type parameter as follows:

response = c.post('/verifyNewMobileUser/', 
    {'phoneNumber': user.get_profile().phone_number,
     'pinNumber': user.get_profile().pin,
     'deviceInfo': {'deviceID': '68753A44-4D6F-1226-9C60-0050E4C00067', 'deviceType': 'I'}},
    'application/json')

And what I get now for request.POST is

<QueryDict: {u"{'deviceInfo': {'deviceType': 'I', 'deviceID': '68753A44-4D6F-1226-9C60-0050E4C00067'}, 'pinNumber': 5541, 'phoneNumber': u' 15551234567'}": [u'']}>

All I want to do is be able to specify a nested dict for my request data. Is there an easy way to do this?

The following works for me (using named args):

geojson = {
        "type": "Point",
        "coordinates": [1, 2]
    }

    response = self.client.post('/validate', data=json.dumps(geojson),
                                content_type='application/json')
