我试图分别创建一个文档和一个子文档。 架构:

const mongoose = require('mongoose');
require('./streets');


const PlaceSchema = new mongoose.Schema({
  place1: String,
  streets: [{type: mongoose.Schema.Types.ObjectId, ref: 'streetSchema'}]
});

module.exports = mongoose.model('place', PlaceSchema);

子架构:

const mongoose = require('mongoose');

const StreetSchema = new mongoose.Schema(
  {
    trafficLights: Number,
    shops: Number,
    busStops: Number,
  },
  { strict: false }
);

module.exports = StreetSchema;

然后我尝试单独实例化街道:

const place = // ...get a certain place from DB;

const street = new Street({
  trafficLights: 1,
  shops: 2,
  busStops: 3,
});

place.streets.push(street)

我得到了

Street is not a constructor

如何创建实例化子模式并将其推入“Streets”数组？

我还尝试将两个模式放在同一个文件中，但是如果不实例化整个“place”模式，就无法到达嵌套数组（streets）。

谢谢。
