我有一个Profile#Index视图，我在其中渲染一个像这样的部分：

<% cache @profiles do %>
  <div class="wrapper wrapper-content">
  <% @profiles.to_a.in_groups_of(3, false).each do |profiles| %>
      <div class="row">
         <%= render partial: "profile", collection: profiles, cached: true %>
      </div>
    <% end %>
  </div>
<% end %>

但是在我的 中app/views/profiles/_profile.html.erb，我有以下内容：

  <% cache profile do %>
    <% elsif current_user.has_role?(:coach) && params[:rating].present? %>
    <div class="contact-box-footer">
      <div class="row text-center avg-ratings">
        <div class="col-lg-3">
          <span class="label label-success">Speed: <%= profile.ratings.find_by(user: current_user).speed %></span>
        </div>
        <div class="col-lg-3">
          <span class="label label-info tackling">Tackling: <%= profile.ratings.find_by(user: current_user).tackling %></span>
        </div>
      </div>
    </div>
    <% end %>
  <% end %>

上面所做的是在结果底部生成标签，这些标签只有params在上面代码中的检查有效/真实时才会出现在结果上。

因此，当登录用户访问时，/他们应该会看到一个配置文件列表，该列表有效且如下所示：

香草列表正确

然后他们去触发相同的 root_path 但带有参数，它看起来（正确）像这样：

参数列表正确

但是，问题是当我返回根页面时，它会混合并匹配来自参数版本的页面的结果与来自 root_path 的普通香草结果，它应该与第一张图像的结果相同上面（又名只是香草结果）。

混乱的列表不正确

我该如何解决？

根据 Austio 的建议，我params[:rating]在局部视图和集合视图中都添加了 。

所以我app/views/profiles/_profile.html.erb现在看起来像这样：

<% cache [params[:rating], profile] do %>
    <% elsif current_user.has_role?(:coach) && params[:rating].present? %>
    <div class="contact-box-footer">
      <div class="row text-center avg-ratings">
        <div class="col-lg-3">
          <span class="label label-success">Speed: <%= profile.ratings.find_by(user: current_user).speed %></span>
        </div>
        <div class="col-lg-3">
          <span class="label label-info tackling">Tackling: <%= profile.ratings.find_by(user: current_user).tackling %></span>
        </div>
      </div>
    </div>
    <% end %>
  <% end %>

虽然两者都不能正常工作，但这里是带有上面代码片段的请求的日志。

这是为了正确的缓存视图。

它仍然不起作用。希望该日志说明了一些可以帮助我深入了解的内容。

当我添加params[:rating]到我的集合和部分缓存键时，它仍然无法在 root_page 上工作（也就是它显示不正确的部分）。以下是该结果的日志：

看起来您的Profile#Index视图正在为使用内部缓存键的配置文件部分使用集合缓存：

<%= render partial: "profile", collection: profiles, cached: true %>

这导致Lola Hessel和Jeremy Verley（以及其他人）在登录用户访问/. 之后访问root_pathwith params 会导致剩余的配置文件被缓存。然后，第三个页面加载对每个配置文件都有缓存命中，并将它们呈现为之前缓存的内容。由于集合缓存首先服务，因此您的配置文件部分中的缓存无效。

你可以在这里阅读：http: //guides.rubyonrails.org/caching_with_rails.html#collection-caching

我假设，从部分渲染中删除集合缓存并结合配置文件部分中适当调整的缓存语句（例如<% cache [profile, params[:rating].present?] do %>）可以解决问题。

将评级作为第二个参数添加到 cache_key

<% 
   caching_key = [@profile]
   caching_key << "with_rating" if params[:rating].present?
   #TODO: Refactor this to cache_key_for_profile(@profile, params) helper
   cache caching_key do 
%>

从设计的角度来看，我建议只使用两个不同的配置文件部分，一个有评级，一个没有，这样你的代码看起来像

<div class="row">
  <% if params[:ratings].present? %>
    <%= render partial: "profile_with_rating", collection: profiles, cached: true %>
  <% else %>
    <%= render partial: "profile", collection: profiles, cached: true %>
  <% end %>
</div>

可以重构两个部分之间共享的代码。profile这明确地让您知道，根据评级是否存在，渲染的部分之间会有差异。
