Issues with record id not found

[Mirv]

Instead of rescuing exception on the application_controller I need to implement Before_validation ... bit of it shown here but research what else is needed...

http://guides.rubyonrails.org/v2.3.11/activerecord_validations_callbacks.html#callbacks-overview

[Mirv]

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
  # This might need to be rescue => e at some point
  rescue_from ActiveRecord::RecordNotFound, :with => :record_not_found

Options:

• first_or_initialize / find_or_create type method where creating a new one is allowed
• general level just =|| or || to Model.first and seed all tables with "Default" so uses know something went wrong to avoid error handling
• rescue ActiveRecord::RecordNotFound & reroute back to referring page with flash message?
