Question

In the test example http://django-rest-interface.googlecode.com/svn/trunk/django_restapi_tests/examples/custom_urls.py on line 19 to they parse the request.path to get the poll_id. This looks very fragile to me. If the url changes then this line breaks. I have attempted to pass in the poll_id but this did not work. So my question is how do I use the poll_id (or any other value) gathered from the url?

Answer 1

Views are only called when the associated url is matched. By crafting the url regex properly, you can guarantee that any request passed to your view will have the poll_id at the correct position in the request path. This is what the example does:

url(r'^json/polls/(?P<poll_id>\d+)/choices/$', json_choice_resource, {'is_entry':False}), 

The json_choice_resource view is an instance of django_restapi.model_resource.Collection and thus the read() method of Collection will only ever act on requests with paths of the expected format.
