试图在我的视图中缓存一行代码

Question

我已尝试使用此代码缓存从flickr中提取用户名。但是，每次进入页面时加载大约需要10秒钟。

- cache do
  - flickr.photos.search(:user_id => 'userid').each do |pic| 

    - unless pic.id == 'picid'

      - photo_info = flickr.photos.getInfo(:photo_id => pic.id) 
      - photo_url = FlickRaw.url_z(photo_info)
      - thumbnail = FlickRaw.url_s(photo_info) 

      %div{"data-src" => "#{photo_url}", "data-thumb" => "#{thumbnail}"}
        .camera_caption.fadeFromBottom
          #{pic.title}
