If you want custom error pages, you'll be best looking at this answer I wrote a few weeks ago

You need several important elements to create custom error routes:

-> Add custom error handler in application.rb:

# File: config/application.rb
config.exceptions_app = self.routes

-> Create /404 routes in your routes.rb:

# File: config/routes.rb
if Rails.env.production?
   get '404', :to => 'application#page_not_found'
end

-> Add actions to application controller to handle these routes

# File: app/controllers/application_controller.rb
def page_not_found
    respond_to do |format|
      format.html { render template: 'errors/not_found_error', layout: 'layouts/application', status: 404 }
      format.all  { render nothing: true, status: 404 }
    end
  end

This is obviously relatively basic, but hopefully it will give you some more ideas on what you can do
