[Answer]-Difference betweeng using Request and specific parameter names in Django

The extra arguments to your function are taken from your path configuration.

You set URL patterns; if you include elements in the URL pattern those will be passed on to your view as extra arguments:

urlpatterns = patterns('',
    url(r'^accounts/(?P<name>\w+)/(?P<some_custom_element>\w+)$', views. get_accounts),
    # ...
)

In the above example the view is configured to listen to any URL starting with accounts/ and including two more elements; those are passed to your view as arguments.

In other words, it is not POST or GET request data that is being passed in to those arguments.

You’d use extra parameters in your path to create friendly, bookmarkable URLs. The path /users/1553537/giorgi-tsiklauri is a lot more readable and friendly than /users?id=1553537.
