Answer 1

Update your 'urls.py':

urlpatterns = patterns('',
    ...
    url(r'^about/$', views.about),
    ...

Answer 2

I think you should register url path to urls.py first. And then update settings.py.

Here are some instructions for you about Django rest framework quickstart. http://www.django-rest-framework.org/tutorial/quickstart/

Answer 3

To send parameters you can added them in the URL and ask for request.GET inside your function, even you can make a POST and ask for request.data inside your function.

your url: /about/?start_date=2016/08/20&end_date=2016/08/21

def about(self, request, *args, **kwargs):
    """"
    Is called by a GET method.
    ISO format: YYYY/MM/DD and in UTC.
    """

    start_date_str = request.GET.get("start_date")
    end_date_str = request.GET.get("end_date")

    return Response({"message": "Hello, world!"})

Another way:

Your url: /about/100/

urlpatterns = patterns('',
...
url(r'^about/(?P<object_pk>[0-9]+)/$', views.example),
...

def example(self, request, object_pk, *args, **kwargs):
    """"
    Is called by a GET method.
    """
    # do something with your object

    return Response({"message": "Hello, world!"})
