node.js - Sequelize 自定义验证是否可能出现多个验证错误？

Question

  deliverableSchedule: {
    type: DataTypes.STRING(64),
    validate: {
      isIn: {
        args: ['onetime', 'recurrent'],
        msg: 'Must be one of "onetime", "recurrent"'
      },
      isRecurrent(value) {
        if (value === 'recurrent' && !this.recurrenceInterval) {
          throw new Error('recurrenceInterval must be set if deliverableSchedule is "recurrent"')
        }

        if (value === 'recurrent' && !(this.recurrenceCount > 0)) {
          throw new Error('recurrenceCount must be greater than 0')
        }
      }
    }
  },

这是我的模型定义。问题是，如果 deliverableSchedule 是 recurrent 并且缺少 recurrenceInterval 和 recurrenceCount

Answer 1

您可以创建自定义错误

class CustomError extends Error {

    constructor(message, errors) {

        super(message);

        this._errors = errors

    }

    get errors() {

        return this._errors;

    }

}

module.exports = CustomError;

然后

 var CustomError= require('./CustomError')


  deliverableSchedule: {
    type: DataTypes.STRING(64),
    validate: {
      isIn: {
        args: ['onetime', 'recurrent'],
        msg: 'Must be one of "onetime", "recurrent"'
      },
      isRecurrent(value) {
        var errroList = [];
        if (value === 'recurrent' && !this.recurrenceInterval) {
          errroList.push('recurrenceInterval must be set if deliverableSchedule is "recurrent"')
        }

        if (value === 'recurrent' && !(this.recurrenceCount > 0)) {
           errroList.push('recurrenceCount must be greater than 0')
        }

        if (errroList.length > 0) {
            throw new CustomError('Is recurrent error. See errors prop for error list', errroList);
        }
      }
    }
  },
