General rescue throughout controller when id not found - RoR

Question

I have stumbled upon a situation where my application looks for an id that does not exist in the database. An exception is thrown. Of course, this is a pretty standard situation

Answer 1

You must use rescue_from for this task. See example in the Action Controller Overview Guide

class ApplicationController < ActionController::Base
  rescue_from ActiveRecord::RecordNotFound, :with => :record_not_found

  private

  def record_not_found
    redirect_to action: :index
  end
end
