ruby-on-rails Rails中的片段缓存

我在rails 7中使用片段缓存,遇到了一个问题。作为参考,这里是我的视图代码,它是views/users/index.html.erb

<p style="color: green"><%= notice %></p>

<h1>Users</h1>

<% cache "users_filter" do %>
  <%= render partial: "users/partials/filter"%>
<% end %>

<table class="">
   <thead>
      <tr>
        <th>Name</th>
        <th>Age</th>
        <th>Action</th>
      </tr>
  </thead>
  <tbody>
  <div id="users">

  <% @users.each do |user| %>
    <% cache user do %>
      <%= render user %>
    <% end %>
  <% end %>

  </div>
  </tbody>
</table>

<% cache "links" do %>
  <%= link_to "New user from here", new_user_path %>
  <%= link_to "Sign Out", destroy_member_session_path, data: { turbo_method: :delete} %>
<% end %>

现在我的问题是,当我改变链接块中的任何内容时,所有其他缓存块(已经缓存并且没有改变)也会重新缓存,而它们不应该。我有单独的缓存键为所有这些,但不知道为什么会发生这种情况。这里有日志供参考。

当你说你要改变链接块中的一些东西时,因为那个块中没有动态数据,我想你的意思是你要改变模板文件中的代码?
Rails缓存键的一部分是模板文件的散列,因此如果模板文件发生更改,缓存将全部刷新。
