Node.js mongoose验证器；必填项：true"；它不起作用了

Mongoose验证器无法验证其“必需：true”的位置

mongoose模式和模型的示例代码

const mongoose = require('mongoose');

const Schema = mongoose.Schema;
let chargingLocationSchema = new Schema({
  values: {
    type: Array,
    required: [true, 'Why no values? Always provide values!']
  },
  chargingHours: {
    type: Number,
    min: 0.1,
    max: [24, 'There is only 24 hours in a day']
  }
}, {
  collection: 'charging_locations'
});

module.exports = mongoose.model('ChargingLocations', chargingLocationSchema);

用于猫鼬验证测试的摩卡测试用例

const expect = require('chai').expect;
const ChargingLocations = require('../chargingLocationsModel');

describe('ChargingLocationsModel', () => {
  it('should be invalid if values is empty', (done) => {
    let cl = new ChargingLocations();

    cl.validate((err) => {
      expect(err.errors.values).to.exist;
      done();
    });
  });

  it('charging hours should be within 24', (done) => {
    let cl = new ChargingLocations({ "chargingHours": 30 });

    cl.validate((err) => {
      expect(err.errors.chargingHours).to.exist;
      done();
    });
  });
});

Mongoose版本：这是因为Mongoose类型数组的默认值为空数组。根据mongoose文档，覆盖定义默认值undefined的。有关详细信息，请参阅。

您是否可能在模式中添加了任何路径验证程序？或者该模式是否高于实际的整个模式用于测试？只是为了能够重现而进行确认。实际整个模式用于测试。默认值：未定义，已解决问题。 mongoose": "^5.1.3
