Question

I want to test the 500 error pages in my Rails app using the development environment.

I already tried this in config/environments/development.rb:

config.action_controller.consider_all_requests_local = false

But this does not seem to have any effect.

Answer 1

You can either:

1. access the application using address other than localhost or 127.0.0.1 which rails considers by default to be local requests
2. Override local_request? in application_controller.rb to something like:

def local_request?
  false
end

The second will stop rails treating requests from localhost and 127.0.0.1 as local requests which combined with consider_all_requests_local = false should show you your 500.html page.
