Intentionally raise an error that needs to be handled manually

Sometimes there are cases when an actual human needs to intervene during edge cases.

# app/lib/manual_intervention_error.rb
class ManualInterventionError < StandardError
  def initialize(message = "An error occured that needs to be addressed manually")
    super
  end
end

class AppointmentsController < ApplicationController
  rescue_from ManualInterventionError, with: :redirect_and_email_support

  def create
    if some_unique_condition
      raise ManualInterventionError
    end
  end
  
  private
  
  def redirect_and_email_support
    redirect_to root_path, alert: "There was an unexpected error. We have notified support."
    ErrorMailer.generic_error.deliver_later
  end
  
end
