MongoDB 日期插入

Question

这是我的架构：

db.createCollection("user_clicks", {
 validator: {
 $jsonSchema: {
 bsonType: "object",
 required: [ "session_id", "country", "browser", "url", "date"],
 properties: {
 session_id: {
 bsonType: "string",
 description: "must be a string and is required" },
 country: {
 bsonType: "string",
 description: "country name and is required"},
 browser: {
 bsonType: "string",
 description: "browser name and is required"},
 url : {
 bsonType: "string",
 description: "user click url and is required"},
 date: {
 bsonType: "date",
 description: "localdatetime and is required"}}}})

这是我用来生成数据的代码：

mgeneratejs `{
  "session_id": "$oid",
  "country": "$country",
  "browser": {
    "$choose": {
      "from": [
        "Firefox",
        "Chrome",
        "Safari",
        "Explorer"
      ],
      "weights": [
        1,
        2,
        2,
        1
      ]
    }
  },
  "url": {
    "$choose": {
      "from": [
        "google.com/images",
        "facebook.com/profile1538713",
        "soundcloud.com/playlist03",
        "some-url.com/home",
        "sinoptik.ua/kyiv"
      ],
      "weights": [
        1,
        2,
        2,
        1,
        3
      ]
    }
  },
  "date": {
    "$date": {
      "min": "2016-08-01T23:59:59.999Z",
      "max": "2016-10-01T23:59:59.999Z"
    }
  }
}` -n 5 | mongoimport --uri="mongodb://localhost:27017/events" --collection user_clicks --mode=insert 

我正在尝试使用 mgeneratejs 和 mongoimport 生成随机日期。问题是我无法插入任何日期，例如："3/13/2019" 或 "2019-03-26T23:44:26Z"（这就是我实际需要）。错误是：

**WriteResult({
    "nInserted" : 0,
    "writeError" : {
        "code" : 121,
        "errmsg" : "Document failed validation"
    }
})**

我尝试像new Date("2019-03-26T23:44:26Z") 这样插入，它可以工作！请帮助如何在每次插入时自动执行 create new Date(date) 或如何解决此问题！

Answer 1

我对您的问题感到困惑...一切正常...您将日期存储在Mongo 中作为Date 对象（类型为Date）..

如果您想以3/13/2019 之类的格式将日期存储在Mongo 中，您可以执行以下操作：

// javascript
let dateToInsert = new Date("3/13/2019");

Answer 2

在插入随机日期之前使用以下内容，它应该可以工作：

new Date(randomDate);
