Consume Json in Python Django

I am trying to consume data from API which is in the following format. Where count can be more than one - 

{u'count': 1, u'previous': None, u'results': [{u'url': u'http://127.0.0.1:8000/offapp/cities/', u'city_name': u'Kolkata', u'id': 1}], u'next': None}

I am using the following method to consume json -

views.py

def employee(request):
    data = requests.get('http://127.0.0.1:8000/offapp/cities/').json()
     context = RequestContext(request, {
    'cities': data.results,
})
return render_to_response('template.html', context)

template.py

{% for city in cities %}
 <a href="{% url 'next_view_name' city.id %}"><p>{{city.city_name}}</p></a>
{% endfor %}

But django can't seem to resolve the name or id and gives the error - 

AttributeError: 'dict' object has no attribute 'city_name'

What is the correct way to use this data? I want to be able to use all the data in results of json in my template and use id to reverse match and go to the next view using id.

I have not used requests json but looking at the documentation you should be using it as a dictionary as the regular json module. In your code use 'cities': data['results'] and then in your template use city.city_name.

Django templates use dot lookups: when the template system encounters a dot in a variable name, it tries a dictionary lookup.

It looks like 'city_name' is a property of data.results[0], not data.city. Sorry I can't test the requests.get(url).json(), so it may need to be data['results'][0]
