我一直在尝试使用rails的缓存功能,但我无法使一些缓存片段过期,尽管它们似乎已过期.使用rails教程网站中指出的"俄罗斯娃娃缓存",我正在使用此配置
<% cache "all_available_releases" do %>
<% @releases.each do |release| %>
<% cache(release) do %>
<html code with>
<%ruby code @release.name blah blah blah%>
<%end%>
<%end%>
<%end%>
我使用release_controller.rb控制器中的外部缓存到期,我使用expire_fragment("all_available_releases")来使片段到期.我在控制器的每个更新或删除或添加条目的方法中使用它.
这是WEBrick的日志,虽然expire片段已经注册,但5行之后读取并使用过期片段,而不应该.此示例是在销毁调用之后.
