Question

我正在尝试使用以下代码在Mongodb上执行简单查询，但是由于某种原因，我没有从查询中获取数据，即使查询为空也返回0

这是屏幕截图 https://screencast.com/t/r3gJCrW4DvI6

这是我的模型doctor.js

var Schema = mongoose.Schema;
var ObjectId = require('mongoose').Types.ObjectId; 

var doctorSchema = new Schema({
  _id: ObjectId,
  name: String
});

var Doctor = mongoose.model('Doctor', doctorSchema);
module.exports = Doctor;

//module.exports = mongoose.model('doctor', doctorSchema);

这是我使用数据库代码的地方

const Doctor = require('../../model/doctor');

async testconnection() {
    console.log("Start Connection");
    let q = 'local.name : moises';
    console.log("Here: " + await Doctor.find({}).select('name').countDocuments());



//Also I tried this

await Doctor.find({}, function(err, users){
            if (err) throw err;
            // object of all the users
            console.log(users);
        })


await Doctor.find({q}, function(err, users){
            if (err) throw err;
            // object of all the users
            console.log(users);
        })
}

这是终端上的输出

Mongo返回空结果，即使有记录
