In Ruby on Rails, what is a good way to get subclass's name in a base controller class?

If both ProductsController and CategoriesController both inherit from GenericController, what is a good way to get the string products in the base class when the URL is pointing to the Products controller? (in this case, the base class's index act开发者_如何学Goion is doing things that would need to use the string products to query the database)

self.class.to_s can be used, and it is Analytics::ProductsController, or params[:controller] can be used and it is analytics/products, so both can be used to extract the sub-class's name. Is using one better than the other, or is a third way even better?

Try

controller_name
