+If you use the path_parameter strategy with resources routes, you will want to setup your routes.rb config file to capture the api version.  You can do that in a few ways.  If you have just a few api routes you might specify the path directly like this:
+```
+resources :cakes, path: '/api/v:api_version/cakes'
+```
+If you are using a lot of routes it might be better to keep them all inside a scope like this:
+```
+scope '/api/v:api_version' do
+  resources :cakes
+end
+```
