ruby-on-rails - 如何根据 URL 中的参数破坏我的缓存键？

转载作者：行者123 更新时间：2023-12-04 14:55:59

我有一个 Profile#Index View ，我在其中渲染了一个部分，如下所示:

<% 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 ，我有以下几点:

  <% 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 %>

上面所做的就是在结果的底部产生标签，这些标签只有在有 params 时才会出现在结果上。检查上面的代码是否有效/真实。

因此，当登录用户转到 / 时他们应该看到一个配置文件列表，它的工作原理如下:

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

然而，问题是当我回到根页面时，它混合并匹配了来自页面参数版本的结果，以及来自 root_path 的普通原版结果，它应该与第一张图像的结果相同以上(又名只是 Vanilla 结果)。

我该如何解决？

根据 Austio 的建议，我添加了 params[:rating]到局部 View 和集合 View 。

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 %>

虽然两者都不能正常工作，但这里是上面代码片段的请求日志。

这是为了正确的缓存 View 。

它仍然不起作用。希望该日志说明了可以帮助我深入了解此问题的内容。

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

最佳答案

它看起来像你的 Profile#Index View 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 %>

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。 .参观 root_path之后使用参数会导致缓存剩余的配置文件。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。由于集合缓存首先服务，因此配置文件部分中的缓存不起作用。

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。
