如何根据网址中的参数来破解我的缓存密钥？

我有Profile#Index视图，我在其中渲染部分：

<% 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 %>

但在我的app/views/profiles/_profile.html.erb中，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 %>

以上所做的是在结果的底部生成标签，并且当上述代码中的params检查有效/无效时，这些标签应仅出现在结果上。

因此，当登录用户转到/时，他们应该看到一个配置文件列表，其工作原理如下：

vanilla-listing-correct

然后他们会触发相同的root_path但是使用params，它看起来（正确地）是这样的：

params-listing-correct

然而，问题是当我回到根页面时，它混合并匹配param的页面版本的结果，以及来自root_path的普通vanilla，它应该只是上面第一张图片的结果相同（也就是香草的结果）。

jumbled-up-listing-incorrect

我该如何解决这个问题？

修改1

Per Austio的建议，我将params[:rating]添加到局部视图和集合视图中。

所以我的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 %>

两者都不能正常工作，但这里是使用上面的代码片段记录请求的日志。

这是针对正确的缓存视图。

它仍然无法运作。希望这个日志说明了一些可以帮助我深入了解的内容。

当我将params[:rating]添加到我的收藏夹中时部分缓存键，它仍然不能在root_page上工作（也就是说它显示不正确的部分）。以下是结果的日志：

2 个答案:

答案 0 :(得分：4)

看起来您的Profile#Index视图正在利用内容缓存键的配置文件部分的集合缓存：

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

当登录用户转到/时，这会导致 Lola Hessel 和 Jeremy Verley （以及其他人）被缓存。之后使用参数访问root_path会导致其余的配置文件被缓存。然后，第三个页面加载具有每个配置文件的缓存命中，并将它们呈现为之前缓存。您的配置文件部分中的缓存无效，因为集合缓存首先服务。

您可以在此处阅读：http://guides.rubyonrails.org/caching_with_rails.html#collection-caching

我认为，从部分渲染中删除集合缓存，并在配置文件部分中使用适当调整的缓存语句（例如<% cache [profile, params[:rating].present?] do %>）可以解决问题。

答案 1 :(得分：2)

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，我建议只有两个不同的个人资料部分，一个有评级，一个没有，所以你的代码看起来像

<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。这明确地告诉您，渲染的profile部分之间存在差异，具体取决于评级是否存在。
