I was using some image cropping example that I found online and now I got confused. There is actually no "crop" method in my controller. Instead (following the guide) I put a

 render :action => 'cropping', :layout=> "admin"

In my create method. That renders a page the view called cropping.html.erb . It works fine but I have no idea how to link or render that page otherwise, like if I wanted to hit a URL directly or press a button to recrop an image. Should I actually create a crop method in my controller and hook it up via routing if I want to be able to do this, or is there a way within my view to link to the same place that renders the cropping action?

Sorry about the confusion :) It doesn't help that the first version of the tutorial did have a cropping method and he removed it!! Any explanation on why one method is better over the other would be great. Thanks!!
