How to test 500.html in rails development env?

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:

Answer 1

Just do a http://localhost:3000/404 or /500 to access these pages and see how they look like.

Answer 2

You should add the below lines to the application_controller,

unless  ActionController::Base.consider_all_requests_local
    rescue_from Exception, :with => :render_500
    if  ActiveRecord::RecordNotFound
      rescue_from Exception, :with => :render_404
    end
    rescue_from ActionController::RoutingError, :with => :render_404
    rescue_from ActionController::UnknownController, :with => :render_404
    rescue_from ActionController::UnknownAction, :with => :render_404
end

Then try running with the below settings.

config.action_controller.consider_all_requests_local = false in config/environments/development.rb:

It will work. Please dont forget to write the function in application_controller.rb to render the layout for each of the error messages.

Answer 3

I think the proper setting to twiddle is this:

config.action_view.debug_rjs = false

Why it's still labelled rjs isn't entirely clear.

Answer 4

In addition to setting: config.consider_all_requests_local = false I also needed to set: config.action_dispatch.show_exceptions = true

Answer 5

None of the proposed solutions worked in my Rails 3 app. The quick and dirty solution for me was to simply hit the error pages directly to see the rendered HTML. For example,

http://0.0.0.0:3000/404.html

http://0.0.0.0:3000/500.html

Answer 6

The only way I've found to do this so far is to set in development.rb

config.consider_all_requests_local = false

Then access the URLs using my local IP address: http://192.168.1.135:3000/blah

The other settings mentioned don't seem to have any effect.
