按日期排列

Question

JSON輸出我想換一個請求的JSON輸出，現在它正在創建記錄時安排，

{"id":1,"title":"The Town","release_date":"2010-10-21","image":"/zX4fKmDXKGt4hlzhAJirdlRKFgO.jpg","user_id":null,"created_at":"2015-12-04T19:57:58.449Z","updated_at":"2015-12-04T19:57:58.449Z","movie_id":"23168","imdb_rating":"7.6"}, 
{"id":2,"title":"Interstellar","release_date":"2014-11-06","image":"/nBNZadXqJSdt05SHLqgT0HuC5Gm.jpg","user_id":null,"created_at":"2015-12-04T19:58:16.600Z","updated_at":"2015-12-04T19:58:16.600Z","movie_id":"157336","imdb_rating":"8.7"}, 
{"id":3,"title":"Django Unchained","release_date":"2013-01-16","image":"/5WJnxuw41sddupf8cwOxYftuvJG.jpg","user_id":null,"created_at":"2015-12-04T20:00:22.411Z","updated_at":"2015-12-04T20:00:22.411Z","movie_id":"68718","imdb_rating":"8.5"}, 
{"id":4,"title":"Moonrise Kingdom","release_date":"2012-05-30","image":"/uw88gWDC0W7AAEhMeQmtdXFV7yR.jpg","user_id":null,"created_at":"2015-12-04T20:00:41.054Z","updated_at":"2015-12-04T20:00:41.054Z","movie_id":"83666","imdb_rating":"7.8"}, 
{"id":5,"title":"Gone Girl","release_date":"2014-10-01","image":"/gdiLTof3rbPDAmPaCf4g6op46bj.jpg","user_id":null,"created_at":"2015-12-05T09:05:08.424Z","updated_at":"2015-12-05T09:05:08.424Z","movie_id":"210577","imdb_rating":"8.2"} 

但我想安排產品上市日期的數據，所以它看起來是這樣的，

{"id":1,"title":"The Town","release_date":"2010-10-21","image":"/zX4fKmDXKGt4hlzhAJirdlRKFgO.jpg","user_id":null,"created_at":"2015-12-04T19:57:58.449Z","updated_at":"2015-12-04T19:57:58.449Z","movie_id":"23168","imdb_rating":"7.6"}, 
{"id":4,"title":"Moonrise Kingdom","release_date":"2012-05-30","image":"/uw88gWDC0W7AAEhMeQmtdXFV7yR.jpg","user_id":null,"created_at":"2015-12-04T20:00:41.054Z","updated_at":"2015-12-04T20:00:41.054Z","movie_id":"83666","imdb_rating":"7.8"}, 
{"id":3,"title":"Django Unchained","release_date":"2013-01-16","image":"/5WJnxuw41sddupf8cwOxYftuvJG.jpg","user_id":null,"created_at":"2015-12-04T20:00:22.411Z","updated_at":"2015-12-04T20:00:22.411Z","movie_id":"68718","imdb_rating":"8.5"}, 
{"id":5,"title":"Gone Girl","release_date":"2014-10-01","image":"/gdiLTof3rbPDAmPaCf4g6op46bj.jpg","user_id":null,"created_at":"2015-12-05T09:05:08.424Z","updated_at":"2015-12-05T09:05:08.424Z","movie_id":"210577","imdb_rating":"8.2"} 
{"id":2,"title":"Interstellar","release_date":"2014-11-06","image":"/nBNZadXqJSdt05SHLqgT0HuC5Gm.jpg","user_id":null,"created_at":"2015-12-04T19:58:16.600Z","updated_at":"2015-12-04T19:58:16.600Z","movie_id":"157336","imdb_rating":"8.7"}, 

這可以做到使用Ruby on Rails嗎？

*編輯*

我用上面的JSON數據，將其放置到名爲movies一個$範圍。然後我用ng-repeat輸出數據。我不能在重複中使用orderBy，因爲我將我的物品放在行中。但是我認爲如果我改變$scope.movies中的順序，所以使用javascript重新排列順序也是可行的。

假設你的工作JSON，你可以使用

json_array.sort_by { |json| Time.parse(json['release_date']) }

2筆記這裏：

1. Time.parse每個產品的開銷（效果會更好）排序前做（但是對於小集合，這不是問題）
2. release_date不是一個日期，但時間...這是有點尷尬。 ;）
