    #show_detailed_exceptions?  ⇒ Boolean  (readonly)
  



  

    

Override this method if you want to customize when detailed exceptions must be shown. This method is only called when consider_all_requests_local is false. By default, it returns false, but someone may set it to request.local? so local requests in production still show the detailed exception pages.
