Question

A. 现有我正在制造一个小目标如下:

@comments = Array.new

comments.collect do |comment|
  @comments << {
    :id => comment.id,
    :content => html_format(comment.content),
    :created_at => comment.created_at
  }
end

@comments.to_json

而这种回报是:

[{"created_at":"2011-03-02T09:17:27-08:00","content":"<p>Random.......</p>","id":734}, {"created_at":"2011-03-02T09:17:27-08:00","content":"<p>asdasd.......</p>","id":714}, {"created_at":"2011-03-01T09:17:27-08:00","content":"<p>Random.......</p>","id":134}, {"created_at":"2011-03-01T02:17:27-08:00","content":"<p>dasdasdasdasd.......</p>","id":3124}]

这里的问题是,我需要列入一些其他零件。我想要的是,有色人反对这样做:

[comments: {"created_at":"2011-03-02T09:17:27-08:00","content":"<p>Random.......</p>","id":734}, {"created_at":"2011-03-02T09:17:27-08:00","content":"<p>asdasd.......</p>","id":714}, {"created_at":"2011-03-01T09:17:27-08:00","content":"<p>Random.......</p>","id":134}, {"created_at":"2011-03-01T02:17:27-08:00","content":"<p>dasdasdasdasd.......</p>","id":3124}, last_load: "123123123123", last_view: "zxczcxzxczxc"]

任何关于我如何利用我前面的内容的想法,以及将其扩大到通过除评论阵列以外的其他项目的想法?

谢谢!

将您的名单添加到散列,然后打电话to_json。

> a = [1,2,3]
 => [1, 2, 3] 
> h = {:comments => a, :foo => "bar"}
 => {:foo=>"bar", :comments=>[1, 2, 3]} 
> h.to_json
 => "{"foo":"bar","comments":[1,2,3]}"
