Question

根据Tom对this问题的回答，我在尝试查询集合上的嵌套字段时收到以下错误。

我尝试使用personalityExams.id.extId = 24232来获取单个用户对象。我想知道查询此问题的最佳方法，以及如何为其构建索引规则。< / p>

以下是用户在firebase中的样子

{
  "users": {
    "93306b91-d5ba-4e06-838c-0ab85fd58783": {
      "createdOn" : 1451495976870,
      "email" : "iyad.bitar@gmail.com",
      "firstName" : "Iyad",
      "lastModifiedOn" : 1451590413654,
      "lastName" : "Bitar",
      "mobile" : "34234333",
      "provider" : "password",
      "userType" : "JS",
      "personalityExams": [
        {
          "extId": "24232",
          "skills": ["teaching"]
        }
      ]
}

在我的javascript中，我试图这样做：

(new Firebase("https://hirely-dev.firebaseio.com/users")).orderByValue("personalityExams/extId").equalTo("24232").on("value", function(snapshot) {user1 = snapshot.val();});

错误：

Uncaught Error: Query.orderByValue failed: Was called with 1 argument. Expects none.

使用Q4 2015版本1.1.3查询嵌套值
