With config.generators becomes a way to configure generators
for current instance only. For example:
module Blog
class Engine < Rails::Engine
config.generators do |g|
g.orm :active_record
end
config.app_generators do |g|
g.test_framework :rspec
end
end
end
such definition sets :active_record as orm for engine and :rspec
as test_framework for application. The values set with app_generators
can be overwritten in application using config.generators as you would
normally do:
module MyApp
class Application < Rails::Application
config.generators do |g|
g.test_framework :test_unit
end
end
end
