我有一個散列數組(或至少我認爲它們是散列),我需要爲它們中的每個散列ID。我確信紅寶石有一些快速的方法來做到這一點......我只是無法弄清楚。我不想迭代數組並創建一個新的數組。如何從紅寶石中的哈希數組中獲取鍵/值對?

你需要修正你的哈希值:'=>',而不是':'和'nil'而不是'null',即它應該看起來像這樣:''lat'=> nil'。在這個例子中你也有一個太多的數組。除非你真的使用散列數組。 – TsukinoMai 2012-04-23 15:55:55
@TsukinoMai我認爲OP實際上發佈了JSON,而不是Ruby。否則,是的,你應該在散列應該如何使用'=>'而不是':'來正確。 – MrDanA 2012-04-23 16:09:08
@MrDanA那麼,如果他想使用ruby方法來獲取信息,他需要將它變成紅寶石哈希。在目前的狀態下,你的解決方案(或任何其他方面)只會給他帶來錯誤。 – TsukinoMai 2012-04-23 16:23:16
