我有宝石工作：可以从它推特和拉信息。
我可以获取这个散列并打印出它的.text部分，但是我不知道如何获取id-str和screen-name-info，我真的需要解析出来。
不知道我做错了什么。
<% Twitter.mentions_timeline.each do |mention| %>
<%= mention.text %> <%# dies on some of em, like mention.id_str - not sure why %>
<br /><hr />
<% end %>
以下是twitter.inspections_timeline散列：

最佳答案
它之所以适用于:text是因为您的mention散列有一个名为:text的键，而您要查找的其他属性（:screen_name和:id_str）则深深地嵌套在其中。
如果仔细观察mention的结构，您会注意到它包含键:entities（与:text处于同一级别），其值是另一个包含键:user_mentions的散列。:user_mentions的值是散列数组。你要找的是在这个散列数组中。
puts mention[:entities][:user_mentions][0][:screen_name] #=> doodleboots
puts mention[:entities][:user_mentions][0][:id_str] #=> 119208666
