### Public Instance Methods

rescue_with_handler(exception) click to toggle source
Calls superclass method

    # File lib/action_controller/metal/rescue.rb, line 9
    def rescue_with_handler(exception)
      if (exception.respond_to?(:original_exception) &&
          (orig_exception = exception.original_exception) &&
          handler_for_rescue(orig_exception))

    end

show_detailed_exceptions?() click to toggle source

Override this method if you want to customize when detailed exceptions must be shown. This method is only called when consider_all_requests_local is false. By default, it returns false, but someone may set it to `request.local?` so local requests in production still shows the detailed exception pages.

    # File lib/action_controller/metal/rescue.rb, line 23
    def show_detailed_exceptions?
      false
    end

### Private Instance Methods

    def process_action(*args)
      super
    rescue Exception => exception
      request.env['action_dispatch.show_detailed_exceptions'] ||= show_detailed_exceptions?
      rescue_with_handler(exception) || raise(exception)
    end
