ruby - 如果值存在则显示散列的内容

Question

我有一个散列:

req = {
  "count" => 50100,
  "results" => [
    {"listing_id" => 615929315, "state" => "active", "user_id" => 140604756, "category_id" => 69150367}, 
    {"listing_id" => 615929311, "state" => "active", "user_id" => 152528025, "category_id" => 69150367}
  ]
}

如果存在特定的 user_id，我想查找并显示整个内部散列。我能找到它:

req["results"][0].select{|key, value| value == 152528025}
# => {"user_id" => 152528025}

然后如何显示整个(嵌套的)散列？

{"listing_id" => 615929311, "state" => "active", "user_id" => 152528025, "category_id" => 69150367}

Answer 1

req["results"].select{|x| x["user_id"] == 152528025}
