Rails route if no route matched

Is there a solution to redirect t开发者_高级运维he user to a specific controller#action if no route matched? I had a "last rule" like this:

 match ":rest" => "application#notfound", :constraints => { :rest => /.*/ }

to redirect all "other" stuff to application#notfound. The problem is that plugins with own routes where set below shis rule and never gets called.

Make a catch-all route and put it as the last rule in your routes.rb file.

match "*rest" => "application#notfound"

you also get whatever the path was as a parameter thru params[:rest] in your controller.

You are definitely not the only person having this problem. I know it's frustrating, but give it some time - I'm confident the Rails team will put together something simple and elegant. I'm in a similar position, only I need to know the incorrect url resource the user entered.

A quick Google search and I found this article demonstrating a full solution to the Rails 3.0 rescue_from ActionController::RoutingError problem. The solution involves Route Globbing and solves my need to both handle incorrect urls and capture the url entered. Hope this helps!

Put this rule last.. Routing matches from top to bottom so if it did find a match then it stops there.

Maybe it's not the best approach, but it will works while you don't find better solution

for rails 2.3, at the application controller, catch the exception like

rescue_from(ActionController::RoutingError) { redirect_to "/xpto" #add your code here }

Rails 3

At initializer put a code like:

module ActionDispatch
  class ShowExceptions
   def render_exception(env, exception)
     if exception.kind_of? ActionController::RoutingError
       render(500, 'it was routing error')
     else
       render(500, "some other error")
     end
   end
 end

end

or something more clean like:

• https://gist.github.com/522924

or:

match '/:anything', :to => "home#routing_error", :constraints => { :anything => /.*/ }

but maybe this last match won't be good for you as it'll override all routes from plugins/engines. I think that best solution is to use custom rack middleware for handling special cases.
