Most of us usually handle the
Active Record Not Found error in ApplicationController and then redirect it to a generic view page. I found a different and more efficient way to handle it.
Intsead of handling the error at ApplicationController level handle it at your Model Controller. Lets you have a controller called PostsController for the model post, then add the line rescue_from
ActiveRecord::RecordNotFound, with: :handle_record_not_found in it and define the method implementation in your controller.
class PostsController < ApplicationController before_action goes_here rescue_from ActiveRecord::RecordNotFound, with: :handle_record_not_found def index end def show end ... def handle_record_not_found # Send it to the view that is specific for Post not found render :not_found end end [/source] The key benefit here is you can have a specific view for every Model you have and you can show customised not found message.
