Question

我有这个json：

{
    "data": [
        "id": "1",
        "name": "Sample test",
        "description": "this is a sample test",
        "category": "tests",
        "points": 100,
        "startDate":"2018-02-15 00:00:00",
        "endDate":"2018-02-22 00:00:00",
        "isActive":true,
        "alreadyAnswered":false,
        "questions":[
            {
                "id": 1,
                "text": "What is your name",
                "type": "text",
            },
            {
                "id": 2,
                "text": "What is your favorite color",
                "type": "select",
                "options": [
                    {
                        "id": 1,
                        "text": "Red",
                        "value": "red"
                    },
                    {
                        "id": 2,
                        "text": "Blue",
                        "value": "blue"
                    }
                ]
            }
        ]
    ]
}

我需要将此json创建到mongo数据库中，以便可以通过节点应用程序获取它。

这是我当前的模式：

let TestSchema = new Schema({
    id: Number,
    name: String,
    description: String,
    category: String,
    points: Number,
    startDate: Date,
    endDate: Date,
    isActive: Boolean,
    alreadyAnswered: Boolean
});

我最大的问题是我不知道如何在我的架构中添加其他对象以复制json，在MySQL中，我会使用hasmany关系将其添加到问题和选项中，但是在这种情况下我需要通过Mongo（创建json并通过路由获取）。

我该如何编程？预先感谢。

data: [
    id: String, //or number, whatever you need
    name: String,
    description: String,
    category: String,
    points: Number,
    startDate: Date,
    endDate: Date,
    isActive: Boolean,
    alreadyAnswered: Boolean,
    questions:[{
            id: String, //or again, number
            text: String,
            type: String,
            options: [
                {
                    id: String, //or number
                    text: String,
                    value: String
                }
            ]
        }
    ]
]

这应该是此JSON的架构

device_meta: [{
   // For example
   device_name: String,
   ID: Number
}]

数组隐式具有默认值[]（空数组），因此不需要default关键字
