It takes advantage of a feature present in Rails 3.2 (and 4.0+, obviously) called exceptions_app. It comes with default error pages but makes it very easy to override them (which you should do).

and rescuing custom errors in a Rails application. It's often useful to map custom Ruby errors to HTTP response status codes and have Rails render the appropriate https://wearestac.com/blog/raising-and-rescuing-custom-errors-in-rails HTML error pages. For example, you might have a controller that is acting as a simple proxy to a third party service such as Twitter or Facebook, and you need any of the HTTP errors encountered when calling those sites to be handled natively by your app. Another use case would be in a Service-oriented architecture (SOA), where you want any errors in your back end error page services propagated to your front end web application. In this post we'll demonstrate rescuing status errors in an imaginary proxy controller using the awesome Faraday gem. For the sake of brevity we've omitted the inclusion of tests though in the wild we'd build such a feature using TDD and our favourite test weapon, RSpec. Not Found To start, let's handle basic 404 Not Found errors that occur rails custom error when calling a service. For this we'll need a custom error class that extends StandardError. # lib/errors/not_found.rb module Errors class NotFound < StandardError; end end Faraday provides a neat Rack-esque middleware feature. By creating our own custom middleware we can catch any Faraday 404s and raise our custom error. Furthermore, we can re-use the middleware anytime we need the same behaviour. # lib/errors/raise_error.rb module Errors class RaiseError < Faraday::Response::Middleware def on_complete(env) raise Errors::NotFound if env[:status] == 404 end end end Now for the proxy controller. # app/controllers/proxy_controller.rb class ProxyController < ApplicationController def index connection = Faraday.new(:url => 'http://someservice') do |f| f.adapter Faraday.default_adapter f.use Errors::RaiseError # Include custom middleware end response = connection.get('/some/resource') render :text => response.body end end At this point any NotFounds raised will still result in a 500 Internal Server Error in Rails. To alleviate this let's create a module that uses rescue_from, catches any custom NotFounds and renders the default 404 page. # lib/errors/rescue_error.rb module Errors module RescueError def self.included(base) base.rescue_from Errors::NotFound do |e| render "public/404", :status => 404 end end end end We can then mixin RescueError into our application controller and handle NotFounds app-wide. # app/controllers/application_controller.rb class ApplicationController < ActionController::Base include Errors::RescueError end Unprocessi
