如何根据 URL 中的参数破坏我的缓存键？
How do I bust my cache key based on the params in the URL?
我有一个 Profile#Index 视图，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 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 %>
上面所做的是在结果底部生成标签，只有在上面的代码中有 params 检查时，这些标签才会出现在结果中 valid/true .
因此，当登录用户转到 / 时，他们应该会看到一个配置文件列表，该列表有效，如下所示：
然后他们触发相同的 root_path 但带有参数，它看起来（正确地）像这样：
但是，问题是当我返回到根页面时，它混合并匹配了页面参数版本的结果，以及 root_path 中的普通原始结果，它应该在哪里与上面第一张图片的结果相同（也就是香草结果）。
我该如何解决这个问题？

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

还是不行。希望该日志说明了一些可以帮助我弄清楚这个问题的东西。

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

将评分添加到 cache_key 作为第二个参数
<%
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，一个带有评级，一个没有，这样您的代码看起来像
<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。这明确地让您知道呈现的 profile 部分之间会有所不同，具体取决于评级是否存在。
您的 Profile#Index 视图似乎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）在登录用户转到 /。之后使用参数访问 root_path 会导致缓存剩余的配置文件。第三个页面加载然后对每个配置文件都有缓存命中，并将它们呈现为之前的缓存。您的个人资料部分中的缓存无效，因为集合缓存首先服务。
您可以在这里阅读：http://guides.rubyonrails.org/caching_with_rails.html#collection-caching
我假设，从您的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 %>）就可以解决问题。
我有一个 Profile#Index 视图，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 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 %>
上面所做的是在结果底部生成标签，只有在上面的代码中有 params 检查时，这些标签才会出现在结果中 valid/true .
因此，当登录用户转到 / 时，他们应该会看到一个配置文件列表，该列表有效，如下所示：
然后他们触发相同的 root_path 但带有参数，它看起来（正确地）像这样：
但是，问题是当我返回到根页面时，它混合并匹配了页面参数版本的结果，以及 root_path 中的普通原始结果，它应该在哪里与上面第一张图片的结果相同（也就是香草结果）。
我该如何解决这个问题？

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

还是不行。希望该日志说明了一些可以帮助我弄清楚这个问题的东西。

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

将评分添加到 cache_key 作为第二个参数
<%
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，一个带有评级，一个没有，这样您的代码看起来像
<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。这明确地让您知道呈现的 profile 部分之间会有所不同，具体取决于评级是否存在。
您的 Profile#Index 视图似乎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）在登录用户转到 /。之后使用参数访问 root_path 会导致缓存剩余的配置文件。第三个页面加载然后对每个配置文件都有缓存命中，并将它们呈现为之前的缓存。您的个人资料部分中的缓存无效，因为集合缓存首先服务。
您可以在这里阅读：http://guides.rubyonrails.org/caching_with_rails.html#collection-caching
我假设，从您的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 %>）就可以解决问题。
