 So far, so good.  It looks pretty similar to the previous case, but we've got better seperation between the different HTTP methods.  We'll also need to update the instance view.

 That's looking good.  Again, it's still pretty similar to the function based view right now.

-Since we're now working with class based views, rather than function based views, we'll also need to update our urlconf slightly.

-    )
-    
-    urlpatterns = format_suffix_patterns(urlpatterns)

 Okay, we're done.  If you run the development server everything should be working just as before.
