RAILS 3.2: How to rescue from "Routing Error" page

Question

How to rescue from RoutingError in Rails 3.2 applications such as redirecting to root_path?

Answer 1

I can think of no circumstances when you would want to rescue from a RoutingError.

If you want all routes not otherwise specified to redirect to some particular action (for custom 'not found' errors, for instance), you can make the last route in your routes.rb file match anything and point there:

match "*path" => 'some_controller#some_action'

Routes are tried in order and the first one which matches is used, so as long as this remains last, it will be used if and only if no other route matches the requested path.
