How to Overwrite ActionController::RoutingError on Rails application to catch "bad Ip" -

i have daily bad request generates lot of logs in production.log this:

f, [2016-02-08t15:39:17.698761 #2437] fatal -- :  actioncontroller::routingerror (no route matches [get] "/sites/default/files/elsevier/eop/s0025-7753(12)00231-x.pdf"):   actionpack (4.0.2) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'   actionpack (4.0.2) lib/action_dispatch/middleware/show_exceptions.rb:30:in `call...' 

in website there isn't route /sites/`: foreign webservice error, , want know ip solve problem.

i have learned this, doesn't work , think need else of code

(i have rails 4.0.2 , upgrade 4.2.5 soon.)

1- in routes.rb, @ end:

 match '*path', :to => 'application#routing_error', via: :all 

2- in application_ontroller: log ip , i need render 404.html if i'm on production or render rails error normaly if i'm on development

  def routing_error(error = 'routing error', status = :not_found, exception=nil)     logger.debug { "---> catch #{request.remote_ip}" }     render status: 404, file: "404.html"   end 

solution:

in routes.rb

class routingerrorconstrain   def initialize     @prodenv=rails.env=="production"   end   def matches?(request)     @prodenv   end end  myapp::application.routes.draw  ...   match '*path', :to => 'application#render_routing_error', via: :all, constraints: routingerrorconstrain.new ... end 

in application_controller.rb:

  def render_routing_error     logger.warn { "bad ip:--------------#{request.ip}---remote_ip:---#{request.remote_ip}---" }     respond_to |format|       format.html { render file: "public/404.html", layout: false, status: status }       format.all { render nothing: true, status: status }     end   end
