创建用于验证的自定义消息

我尝试的内容

我的架构：

var locationSchema = new mongoose.Schema({

    locationId: { type: String, required: true,index:true },
    stockingLocationId: { type: String, required: true,index:true},
    parentStockingLocationId: { type: String },
    stockingLocationDescription: { type: String },
    created: { type: Date, default: Date.now  },
    lastModified: { type: Date, default: Date.now },
    isActive: { type: Boolean , default : true },
    isDeleted: { type: Boolean , default : false }

});

locationSchema.index({locationId:1, stockingLocationId:1}, { unique: true });

我想为后一行的uniquess验证抛出自定义消息。

locationSchema.index({locationId:1, stockingLocationId:1}, { unique: true });

您可以尝试 mongoose-unique-validator 包，为Mongoose架构中的唯一字段添加预保存验证，并且还可以更轻松地处理错误，因为当您收到Mongoose验证错误时您尝试违反唯一约束，而不是来自MongoDB的E11000错误：

var mongoose = require('mongoose');
var uniqueValidator = require('mongoose-unique-validator');

var locationSchema = new mongoose.Schema({

    locationId: { type: String, required: true,index:true },
    stockingLocationId: { type: String, required: true,index:true},
    parentStockingLocationId: { type: String },
    stockingLocationDescription: { type: String },
    created: { type: Date, default: Date.now  },
    lastModified: { type: Date, default: Date.now },
    isActive: { type: Boolean , default : true },
    isDeleted: { type: Boolean , default : false }

});

locationSchema.index({locationId:1, stockingLocationId:1}, { unique: true });
locationSchema.plugin(uniqueValidator, { message: 'Error, expected {PATH} to be unique.' });
