如何使用Strongloop Loopback REST API包含和排序數組？

Question

我在現有模型中添加了一個數組，在名爲User/Questions的模型中添加了術語 {"include" : ["answers"]}。因此，如果我得到用戶/問題模型，我會得到一個答案列表。但是，現在我想根據dateCreated在我的問題模型中排列答案。爲此，我應該如何編輯我放置在REST Strongloop API過濾器中的術語？

//QuestionModel 

[ 
{ 
"question": "where is the coffee shop?" 
"answers": [ 
//answer model included 
    { 
    "answer": "I am not sure", 
    "dateCreated": 4/1/16, 
    }, 
{ 
    "answer": "maybe try 5th avenue?", 
    "dateCreated": 4/3/16, 
    }, 
    { 
    "answer": "oh its by the bakery", 
    "dateCreated": 4/2/16, 
    } 
] 

Answer 1

範圍需要包括在當querying related models。因此，對於您的示例，這將是沿線：

{"include": {"relation": "answers", "scope": {"order" : "dateCreated DESC"}}}
