The content that you requested could not be found.

You tried to access '#{@not_found_path}', which is not a valid page.

Want to
%a{href: root_path} go back to our home page
and try again?
class ErrorsController < ApplicationController
def error_404
@not_found_path = params[:not_found]
end
def error_500
end
end
rails generate controller errors error_404 error_500
get "errors/error_404"
get "errors/error_500"
unless Rails.application.config.consider_all_requests_local
match '*not_found', to: 'errors#error_404'
end
