Question

Mongoose验证器未能验证“required：true”的位置。

mongoose架构和模型的示例代码

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Mocha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：

mongoose": "^5.1.3

错误，因为它没有将“值”视为强制性的：

ChargingLocationsModel
    1) should be invalid if values is empty
    √ charging hours should be within 24


  1 passing (35ms)
  1 failing

  1) ChargingLocationsModel
       should be invalid if values is empty:
     Uncaught TypeError: Cannot read property 'errors' of null

Answer 1

这是因为Mongoose类型数组的默认值为empty array。根据mongoose文档，覆盖定义默认值为undefined。有关详细信息，请参阅mongoose documentation for arrays。

用于“required：true”的mongoose验证器不起作用
