Extending scaffold generator

Question

Is there some way, to trigger my own generator after the scaffold generator is done?

Something like rails g scaffold HighScore game:string score:integer will trigger my_generator created by rails generate generator my_generator

I solve this in another way.

Originally my thought was:

• I run a scaffold generator
• IT generates all standard files
• Then it will run my own scripts (generators) after

You can customize scaffold workflow as the documentation says

So I defined a scaffold generator like this

config/application.rb

# resource_controller defines which generator to use 
# for generating a controller when using rails generate the resource. 
# Defaults to :controller.

# scaffold_controller different from resource_controller, defines which generator 
# to use for generating a scaffolded controller when using rails generate scaffold. 
# Defaults to :scaffold_controller.

config.generators do |gen|
  gen.orm :active_record
  gen.template_engine :haml
  gen.test_framework :rspec,
                     fixtures: true,
                     view_specs: true,
                     helper_specs: true,
                     routing_specs: true,
                     controller_specs: true,
                     request_specs: true
  gen.helper :helper_and_policy
  gen.scaffold_controller :controller_with_smart_listing
  gen.fixture_replacement :factory_bot, dir: "spec/factories"
end

As you can see I only changed gen.scaffold_controller which suits to my problem. But I think there is an option for changing a scaffold model generator as well.

Then I created a folder for my generator lib/generators/rails/controller_with_smart_listing/

I do not remember how I generate this structure but I share files in a repository
