如何删除评论和评论从这个哈希计数

Question

如何从这个哈希删除评论和评论计数。我需要没有评论的数据。

{"id"=>"149536368430_10151515647758431", "from"=>{"category"=>"Product/service", "name"=>"Swiffer", "id"=>"149536368430"}, "to"=>{"data"=>[{"category"=>"Media/news/publishing", "name"=>"Hispanicize", "id"=>"119781464743025"}, {"category"=>"Household supplies", "name"=>"P&G everyday", "id"=>"142671152446083"}]}, "message"=>"Swiffer will be at Hispanicize in Miami Wednesday-Saturday this week.

my_hash = {"id"=>"149536368430_10151515647758431", "from"=>{"category"=>"Product/service", "name"=>"Swiffer", "id"=>"149536368430"}, "to"=>{"data"=>[{"category"=>"Media/news/publishing", "name"=>"Hispanicize", "id"=>"119781464743025"}, {"category"=>"Household supplies", "name"=>"P&G everyday", "id"=>"142671152446083"}]}, "message"=>"Swiffer will be at Hispanicize in Miami Wednesday-Saturday this week.

my_hash.reject { |key,value| key == 'comments' } 

这将返回一个没有注释的散列。
