ruby-on-rails - URL のパラメーターに基づいてキャッシュキーを破棄するにはどうすればよいですか?

Question

私は次のProfile#Indexようにパーシャルをレンダリングするビューを持っています:

<% 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 %>

しかし、私app/views/profiles/_profile.html.erbのには、次のものがあります。

  <% 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 %>

上記が行うことは、結果の下部にラベルを生成することです。これらのラベルはparams、上記のコードのチェックが有効/真である場合にのみ結果に表示されます。

そのため、ログインしたユーザーがに/アクセスすると、次のように機能するプロファイルのリストが表示されます。

次に、同じ root_path をトリガーしますが、params を使用すると、(正しく) 次のようになります。

ただし、問題は、ルートページに戻ると、ページのパラメーターのバージョンの結果と、最初の画像と同じ結果になるはずの root_path の通常のバニラの結果を混ぜ合わせて一致させることです。上記（別名、単なるバニラの結果）。

これを修正するにはどうすればよいですか?

編集 1

Austio の提案に従ってparams[:rating]、部分ビューとコレクションビューの両方にを追加しました。

だから私のapp/views/profiles/_profile.html.erb今は次のようになります：

<% 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 %>

どちらも正しく動作しませんが、上記のコードスニペットを使用したリクエストのログを以下に示します。

これは、正しいキャッシュビュー用です。

それでもうまくいきません。そのログが、この問題の真相を突き止めるのに役立つ何かを示していることを願っています。

コレクションと部分キャッシュキーの両方に追加params[:rating]しても、まだ root_page で機能しません (正しくないパーシャルが表示されます)。その結果のログは次のとおりです。

あなたのProfile#Indexビューは、内部キャッシュキーを利用するプロファイルパーシャルのコレクションキャッシュを利用しているようです。

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

これにより、ログインしているユーザーが/. 後でroot_pathwith params にアクセスすると、残りのプロファイルがキャッシュされます。3 回目のページ読み込みでは、すべてのプロファイルのキャッシュヒットがあり、以前にキャッシュされたようにレンダリングされます。コレクションのキャッシュが最初に提供されるため、プロファイルパーシャル内のキャッシュは効果がありません。

ここでそれについて読むことができます: http://guides.rubyonrails.org/caching_with_rails.html#collection-caching

パーシャルプロファイル内の適切に適合されたキャッシュステートメント ( など<% cache [profile, params[:rating].present?] do %>) と組み合わせて、パーシャルレンダリングからコレクションキャッシュを削除すると、うまくいくと思います。

評価を 2 番目のパラメーターとして cache_key に追加します

<% 
   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 
%>

設計の観点から、2 つの異なるプロファイルパーシャルを使用することをお勧めします。1 つは評価あり、もう 1 つは評価なしで、コードは

<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>

2 つのパーシャル間で共有されるコードはリファクタリングできます。profileこれにより、レーティングが存在するかどうかに応じて、レンダリングされたパーシャルに違いがあることを明示的に知ることができます。
