Question

我在MongoDB中使用文档验证，它应该验证我插入users集合的文档属性的数据类型。以下是我以完全相同的顺序执行的命令

> db.createCollection("users");
{ "ok" : 1 }

> db.runCommand({
...  collMod: "users",
...  validator: {
...    $and : [
...      { "nm" : { $type : "string" }},
...      { "mob" : { $type : "int" }},
...    ]
...  },
...  validationAction: "error",
...  validationLevel: "strict"
... });
{ "ok" : 1 }

> db.users.insertOne(
  {
...  "nm" : "foo",
...  "eml" : "foo@gmail.com",
...  "mob" : 12345,
...  "isa" : true,
...  "blod" : "O+",
...  "sid" : 1,
...  "cid" : 1,
...  "aid" : 1,
...  "add" : "bar",
...  "dob" : "16-Sep-1992"
...});

但是，只要我运行最后一个insertOne命令，它就会使文档验证失败并输出以下输出。

我试图弄清楚如果我的验证器或我插入但不能的数据是什么问题。任何帮助将不胜感激。

在文档验证中使用"number"代替"int"：

运行

db.runCommand({
   collMod:"users",
   validator:{
      $and:[
         {
            "nm":{
               $type:"string"
            }
         },
         {
            "mob":{
               $type:"number"
            }
         },

      ]
   },
   validationAction:"error",
   validationLevel:"strict"
})

它应该可以正常工作

由于文档验证，插入查询突然失败
