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

Question

我通過在名為 User/Questions 的模型中添加術語{"include" : ["answers"]}在現有模型中包含一個數組。 因此，如果我得到用戶/問題模型，我將得到一個答案列表。 但是，現在我想根據 dateCreated 在我的問題模型中對答案進行排序。 為此，我應該如何編輯放置在 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

查詢相關模型時需要包含scope 。 因此，對於您的示例，它將遵循以下原則：

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