ruby on rails - raise ActiveRecord::RecordNotFound (or any 404 status) for invalid date -

In my controller controller, I have a date object to use date.new Use is in my ActiveRecord

  end_range = Date.new (params [: year] .to_i, consultation [[month] .to_i, consultation [[day] .to_i) .end_of_day.to_formatted_s (: db)  40  for the day at most  date. New  failed (as expected). However, I should not get 500 errors, if a user types something like this, but instead 404 error (because you will not actually be able to record from one day of  40 ). 
 
 I  if  is extended to  ActiveRecord :: RecordNotFound  if  and  if you fail, 500 error before running conditional (and again 404 is not returning).  
 Does anyone know the better way to fix this, or can there be a more lawful statement of condition to fail to defeat  date.new ? 
 
 
 In this case you can save an exception and increase each other Wants to re-map those types which are not in type types: 
 
  Start def show end_range = date.new (...) Rescue argument Argument # Invalid date raise ActiveRecord: : RecordNotFound End Rescue ActiveRecord :: RecordNotFoun De Render (: partial = & gt; 'Not_found',: layout = & gt; 'app': position = & gt;: not_found) end  
 < P> Although it is correctly presented Doing and failing can be more efficient now. 
 
  DEF show start end_order = date  
 
 You can also do this:     using this application controller's  rescue_from  method In a more broad sense: 
 
  class ApplicationController & lt; ActionController :: Base Rescue_frame Enter Enter Argument (: partial = & gt; 'Exception / Logic_Rar',: Layout = & gt; 'Application',: Status => not_found) End End  < / Pre>
