显示哈希的内容(如果存在值)

Question

我有一个哈希：

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user_id，我想查找并显示整个内部哈希。我可以找到它：

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

然后如何显示整个(嵌套(哈希？

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

Answer 1

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