How do I refer the id of schema in mongoose

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const CollageSchema = new Schema({
  collage_name: {
    type: String,
    required: [true, 'Name field is required']
  },
  university_id: {
    type: [{
      type: Schema.Types.ObjectId,
      ref: 'university'
    }]
  },
  type: {
    type: String,
    enum: ['autonomous', 'private'],
    required: [true, 'type field is required']
  }
});

const Collage = mongoose.model('collage', CollageSchema);
module.exports = Collage;

I have referenced _id of UniversitySchema in CollageSchema, but it will be taking any university_id that will not present in university table. Please help me. Thank you

There isn't any validation by default in the schema for any Reference Object Id What you can do is set up one synchronous validation and make a findOne call in it to validate.
