我无法在 mongodb 中创建用户，一定是功能错误？

Question

嗨，我想在屏幕上看到用户的所有信息，但我无法在 mongodb 中添加用户。 Locations Schema中的用户位置信息。但我不知道如何获取位置信息（即城市，城镇......）来输入UserSchema。这是我的代码：

用户架构：

var userSchema = Mongoose.Schema({ 

        name:{type: String,require:true},
        surname: {type: String,require:true},
        tel: {type: String,require:true},
        age: {type: String,require:true},
        mevki_id: {type: String,require:true},
        location_id: { type: [Mongoose.Schema.Types.ObjectId], ref: 'locations' }



});

Create User Function :
this.createUser = function (req, res, next) {
       var lok=new Location({il:req.params.il,ilce:req.params.ilce});
               lok.save(function(err){
   var user=new User({name:req.params.name,surname:req.params.surname,tel:req.params.tel,age:req.params.age,mevki_id:req.params.mevki_id,location_id:user});
         user.save(function(err){

          user.location_id=lok;
                 });
 return res.send({})
                 });    
                 }

谢谢:)

//define this as your schema in your file

var userSchema = new Schema({
    name: {type: String, required: true},
    surname: {type: String, required: true},
    tel: {type: Number, required: true},
    age: {type: Number, required: true},
    mevki_id: {type: String, required: true},
    location_id:{type:String,required:true}
});
var CollectionModel_user = conn.model('users', userSchema)

return function (req, res, next) {
        req.Collection_user = CollectionModel_user;
        next();
    }

   // create a route which can create a route in your
   // app.js or main.js file that will create a new
   // collection in your mongo.

    router.all('/user/create', function (req, res) {
    var create = req.Collection_user;
    var name = req.body.name;
    var surname = req.body.surname;
    var tel = req.body.tel;
    var age = req.body.age;
    var mevki_id = req.body.mevki_id;
    var location_id = req.body.location_id;
    var record = new create({
        name: name,
        surname: surname,
        tel: tel,
        age: age,
        mevki_id: mevki_id,
        location_id: location_id
    });
    if (name.length > 0) {
        record.save(function (err, result) {
            if (err) {
                res.json({status: 0, message: err})
            } else {
                res.json({status: 1, message: " success"});
            }
        })
    } else {
        res.json({status: 0, msg: "Invalid Fields"});
    }
});
