[Rails] Re: Question re Non Standard ID and Restful routes.

Just using "map.resources :app" is enough to let you use "/show/:application_id" if you want to.

In your model, you can overwrite the to_param method to use application_id instead of id:

def to_param
  application_id
end

That will cause URLs generated by URL helpers to use application_id instead of id

Then in your controller, you just need to do "App.find_by_application_id(params[:id])"
