Override default scaffold generator in rails 3

Question

I\'ve created a generator for a controller in rails 3. Now I want to use this generator as the default generator when using the scaffolding generator.

Is that possib

If you simply want to use your own controller template, you can just put it in lib/templates/rails/scaffold_controller/controller.rb

If you want to replace the scaffold_controller_generator code itself, for example, so that the controller scaffold generates additional class files. you can create lib/generators/rails/my_scaffold_controller/my_scaffold_controller_generator.rb with templates under lib/generators/rails/my_scaffold_controller/templates.

Remember to point rails at your new scaffold_controller in config/application.rb:

config.generators do |g|
  g.scaffold_controller = "my_scaffold_controller"
end

For my_scaffold_controller_generator.rb you could copy from the railties gem under railties-3.x.x/lib/rails/generators/rails/scaffold_controller if you want to modify default behaviour, or inherit from it if you just want to add functionality:

require 'rails/generators/rails/scaffold_controller/scaffold_controller_generator'

module Rails
  module Generators
    class MyScaffoldControllerGenerator < ScaffoldControllerGenerator
      source_root File.expand_path("../templates", __FILE__)

      def new_funtionality
      end

    end
  end
end
