如何比较猫鼬模式中的密码？

Question

如何比较password 和password_confirmation，如果它们不匹配，我将在错误消息中打印"Passwords don't match"？

const userSchema = new Schema(
  {
    username: {type: String, required: [true, "Please enter a username"], unique: [true, "Username taken"]},
    password: {type: String, required: true, minLength: [8, "Minimum password lenth is 8"]},
    password_confirmation: {type: String}
  },
  { timestamps: true }
);

您可以在架构中使用验证器。 https://www.npmjs.com/package/validator

passwordConfirm: {
type: String,
required: [true, 'Please confirm ypur password'],
validate: {
  // this only works on CREATE and  SAVE!!!!
  validator: function (el) {
    return el === this.password;
  },
  message: 'Password are not the same',
},

}
