    #after_initialize(&block)

    #app_generators {|@@app_generators| ... } 
  



  

    

This allows you to modify application’s generators from Railties.



Values set on app_generators will become defaults for application, unless application overwrites them.


  





  
Yields:

    #app_middleware  
  



  

    

This allows you to modify the application’s middlewares from Engines.



All operations you run on the app_middleware will be replayed on the application once it is defined and the default_middlewares are created
