I've been trying to use the code here:
but I'm getting errors like:
undefined method `template_exists?' for #<StaticController:0xb74cbe4c>
How can I update this method to Rails 2.5? Probably there are other deprecated things too.
The method call template_exists? is deprecated as of Rails 2.2.1 (see: Rails APIdock)
A little bit of digging revealed the solution, by the original author, in the following article article. Basically requires adding the method into the StaticController, derived from ApplicationController and thus gives the method.
