But something like en/file.foo throws 404. So only valid suffixes throw a 500.

I could not find how to perform the 500 page render: class ApplicationController < ActionController::Base rescue_from StandardError do send_email_of_error # what goes here? end ... end ruby-on-rails share|improve this question asked Mar 9 '12 at http://stackoverflow.com/questions/9638751/how-to-render-500-page-in-rescue-from 17:58 mbdev 1,97153148 add a comment| 2 Answers 2 active oldest votes up vote 6 down vote accepted Raising the exception again will likely to what you want: rescue_from StandardError do |exception| send_email_of_error raise exception end You could also call render to render your own page, the docs have an example doing this. But why reinvent the wheel? The exception notifier gem already does this and is customizable and tested. share|improve this answer answered Mar 9 '12 at 18:04 Andrew Marshall 63.9k12134153 that's great. I found the original was not updated for two years. i'll try this version. –mbdev Mar 9 '12 at 18:29 Unfortunately, that turns out to render the error page, but with a status code of 200. –Steve Jorgensen Oct 30 '14 at 22:01 add a comment| up vote 3 down vote This is an approach that maybe fits your needs: class ApplicationController < ActionController::Base rescue_from Exception, :with => :render_500 def render_500(exception) @exception = exception render :template => "shared/500.html", :status => 500 end end share|improve this answer answered Mar 9 '12 at 18:14 awenkhh 2,0061020 2 One should never rescue from Exception.

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 http://www.slideshare.net/snmaynard/ruby-rails-error-handling-18123823 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 services rails raise 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 when rails throw 500 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 Unprocessible Entity and
