Rescue from routing error rails 3.1

Question

How to rescue from RoutingError in rails 3.1 application. If i'm nt mistaken it was possible to use rescue_from RoutingError in application controller but now it's not possible.

Answer 1

There is no great way to handle it, but there are a few workarounds. The discussion here yields the following suggestion:

Routes

Add the following to your routes file:

match "*", :to => "home#routing_error"

and handle the error in this action:

def routing_error
  render text: "Not found, sorry", status: :not_found
end

Answer 2

I wasn't able to replicate @matthew-savage's results. However, per the Rails guide on route globbing and this question on another StackOverflow question, I solved this issue like so:

routes.rb

match "*gibberish", :to => "home#routing_error"

notice how I included text after the wildcard. The controller is fine as shown above:

controller/home_controller.rb

....
def routing_error
    render text: "Not found, sorry", status: :not_found
end
