枚举的Mongoose模型自定义错误消息

Question

我想自定义我的Mongoose模型生成的验证消息.

我倾向于不直接在架构对象上放置我的验证(例如必需),因为没有自由拥有自定义错误消息.例如

sourceAccountId: {
  type: Schema.ObjectId,
  require: true,
  ref: 'Account'
}

相反,我做了以下.

sourceAccountId: {
  type: Schema.ObjectId,
  ref: 'Account'
}

ConnectionRequestSchema.path('sourceAccountId').required(true, 'Source Account is required.');

当字段具有枚举约束时,我无法找到覆盖默认枚举消息的方法.

我的模型列在下面,状态验证消息适用于所需,但不适用于枚举.

'use strict';

var _ = require('lodash');

var mongoose = require('mongoose');

var Schema = mongoose.Schema;

var ConnectionRequestSchema = new Schema({
  created_at: { type: Date },
  updated_at: { type: Date },

  sourceAccountId: {
    type: Schema.ObjectId,
    ref: 'Account'
  },

  status: {
    type: String,
    enum: ['pending', 'accept', 'decline'],
    trim: true
  }
});

// ------------------------------------------------------------
// Validations
// ------------------------------------------------------------

ConnectionRequestSchema.path('sourceAccountId').required(true, 'Source Account is required.');
ConnectionRequestSchema.path('status').required(true, 'Status is required.');
//ConnectionRequestSchema.path('status').enum(['pending', 'accept', 'decline'], 'Status is invalid, valid values include [pending, accept, decline]');

// ------------------------------------------------------------
// Save
// ------------------------------------------------------------

ConnectionRequestSchema.pre('save', function (next) {
  var now = new Date().getTime();

  this.updated_at = now;
  if (!this.created_at) {
    this.created_at = now;
  }

  next();
});

module.exports = mongoose.model('ConnectionRequest', ConnectionRequestSchema);

Answer 1

尝试类似的东西:

var enu = {
  values: ['pending', 'accept', 'decline']
, message: 'Status is required.'
}


var ConnectionRequestSchema = new Schema({
  ...

  status: {
    type: String
  , enum: enu
  , trim: true
  }
});

Answer 2

difficulty: {
        type: String,
        required: [true, 'A tour must have a difficulty.'],
        enum: {
            values: ['easy', 'medium', 'difficult'],
            message: 'Difficult is either easy, medium, difficult.'
        }
    }
