Dynamic Method Handling

  

    This class handles dynamic methods through the method_missing method
      in the class Rails::Railtie::Configuration


Instance Attribute Details



  

    #autoload_once_paths   (rw)
  



  

    

An array of custom autoload once paths. These won’t be eager loaded unless you push them to #eager_load_paths too, which is recommended.



This collection is empty by default, it accepts strings and ::Pathname objects.



If you’d like to add lib to it, please see autoload_lib_once.

An array of custom eager load paths to be added to the ones defined automatically by ::Rails. Anything in this collection is considered to be an autoload path regardless of whether it was added to #autoload_paths.



This collection is empty by default, it accepts strings and ::Pathname objects.
