Lots of times I dont need a seperate stylesheet, javascript file, or helpers when generating or scaffolding

# config/application.rb

config.generators do |generate|
  generate.helper false

  generators.test_framework = false
  
  generators.assets = false
  # OR
  generators.stylesheets = false
  generators.javascripts = false
end
