使用 jsonSchema 的 Mongo 3.6 调试验证

Iva*_*dad 1 jsonschema mongodb mongodb-3.6

我正在学习 mongodb 大学的课程以学习 3.6 版中的新功能,但我无法解决我的验证器无效的原因。

这就是我创建集合的方式:

db.getSiblingDB("TSA").createCollection("claims", {
    validator: {
        $jsonSchema: {
            bsonType: "object",
            properties: {
                _id: { },
                airportCode: { type: "string", minLength: 3 },
                airportName: { type: "string" },
                airlineName: { type: "string", minLength: 5 },
                claims: {
                    bsonType: "object",
                    properties: {
                        itemCategory: { bsonType: "array", maxItems: 3 },
                        amount: { type: "string", pattern: "^\$.*" }
                    }
                }
            },
            required: ["airportCode", "airlineName", "claims"],
            additionalProperties: false
        }
    }
})

然后,我尝试插入这个对象:

db.getSiblingDB("TSA").claims.insertOne({
    "airportCode": "ABE",
    "airportName": "Lehigh Valley International Airport, Allentown",
    "airlineName": "MongoAir",
    "claims": {
        "claimType": "Property Damage",
        "claimSite": "Checked Baggage",
        "itemCategory": [ "Sporting Equipment & Supplies" ],
        "amount": "$180.00"
    }
})

得到以下错误:

WriteError({
    "index" : 0,
    "code" : 121,
    "errmsg" : "Document failed validation",
    "op" : {
        "_id" : ObjectId("5a705318d3d6c18337f07282"),
        "airportCode" : "ABE",
        "airportName" : "Lehigh Valley International Airport, Allentown",
        "airlineName" : "MongoAir",
        "claims" : {
            "claimType" : "Property Damage",
            "claimSite" : "Checked Baggage",
            "itemCategory" : [
                    "Sporting Equipment & Supplies"
            ],
            "amount" : "$180.00"
        }
    }
})

我的问题是,是否有某种方法可以调试验证器,例如“属性 X 必须是 Y 类型”,而不是获得通用的“文档验证失败”?

从 MongoDB 3.6 开始,没有反馈机制可以通知在服务器端检查期间文档的哪一部分未通过验证。相应的功能请求已打开:SERVER-20547: Expose the reason an operation failed document validation。目前,如果需要详细的反馈,则由应用程序代码执行自己的验证。
