（キャッシングdalli）は静的ページのパフォーマンスを向上させる非常に強力なプラグインです。
しかし、頻繁に更新されるページネーションのある動的ページはどうでしょうか?
セットアップする正しい方法は何dalliですか?
たとえば、私が遭遇した1つの問題dalli：ページネーションを使用するときに、異なるparams [:page]を同じページとして認識します:(
dalli両方を使用する場合、システムをどのように設計しますか
- 頻繁に更新されるページ
- あまり更新しないページ
例えば。User、Community、Topic、などの 4 つのモデルがあります。Comment(defined Polymorphic to both Community, and Topic. They can be created or shown in #show pages)
みたいな
- コミュニティ > (has_many) > トピック > (has_many) > コメント
- コミュニティ > (has_many) > コメント
- すべてユーザー（作成者）に属します
私の現在のコードはこのようなものです（これはかなり長いです。申し訳ありません）
キャッシュを使用するときにページネーションの問題に直面しています...

....
if params[:sort] == 'new'
@communities = Community.scoped.page(params[:page]).order("created_at DESC")
elsif params[:sort] = 'popular'
@communities = Community.scoped.page(params[:page]).order("follow_count DESC")
elsif params[:sort] = 'reputation'
@communities = Community.scoped.page(params[:page]).order("reputation_count DESC")
else
@communities = Community.scoped.page(params[:page]).order("created_at DESC")
end

end
def show
@community = Community.find(params[:community_id])
@comments @community.comments.page(params[:page]
@topics = @community.topics.limit(10)
end
views/communities/index.html.erb 注: ただし、次の params[:page]:( キャッシングは別のページを同じコンテンツとして認識しているようです...
#here, the url will could be something like this example.com/communities?utf8=✓&location=14&genre=3&search=strawberry
But this is going to create gigantic petterns of the caches:(
So I want to make it work only when params[:sort] was not empty. Because, no other parameters come with when params[:sort] is not empty.
It could be like, example.com/communities?sort=new, example.com/communities?sort=popular, example.com/communities?sort=reputation
