ruby-on-rails – Rails Cache Sweeper

概述我正在尝试实现一个缓存清理程序,它将过滤特定的控制器 *** 作. class ProductsController < ActionController caches_action :index cache_sweeper :product_sweeper def index @products = Product.all end 我正在尝试实现一个缓存清理程序,它将过滤特定的控制器 *** 作.

class ProductsController < ActionController      caches_action :index      cache_sweeper :product_sweeper      def index         @products = Product.all     end     def update_some_state      #... do some stuff which doesn't trigger a product save,but invalIDates cache    endend

清扫车类：

class Productsweeper < ActionController::Caching::sweeper    observe Product    #expire fragment after model update    def after_save       expire_fragment('all_available_products')       end    #expire different cache after controller method modifying state is called.    def after_update_some_state        expire_action(:controller => 'products',:action => 'index')     endend

ActiveRecord回调’after_save’将正常工作,但似乎永远不会调用控制器 *** 作’after_update_some_state’上的回调.

解决方法 在尝试获取控制器 *** 作的回调时,看起来我只是错过了控制器名称.我的清扫工应该是：

class Productsweeper < ActionController::Caching::sweeper    observe Product    #expire fragment after model update    def after_save       expire_fragment('all_available_products')       end    #expire different cache after controller method modifying state is called.    def after_products_update_some_state        expire_action(:controller => 'products',:action => 'index')     end    #can also use before:    def before_products_update_some_state        #do something before.     endend
