Question

我为每个拥有node和mongoose的用户创建了一个动态模式，如下所示。

    var mongoose = require('mongoose');
    var Schema = mongoose.Schema;
    require('mongoose-currency').loadType(mongoose);
var Currency = mongoose.Types.Currency;

var values = 'Credit Debit'.split(' ');

var schema = new Schema({
        amount: {
            type: Currency,
            required: true
        },
        type: {
            type: String,
            enum: values
        },
        description: {
            type: String,
            required: true
        }
    },
    {
        timestamps: true
    });

exports.create_database = function(mobile) {
    return mongoose.model('personal_'+mobile, schema, 'personal_'+mobile);
};

我在下面给出的个人路由器代码中使用了这个

var express = require('express');
var bodyParser = require('body-parser');
var mongoose = require('mongoose');

var database = require('../models/personal');
var Verify = require('./verify');

var personalRouter = express.Router();
personalRouter.use(bodyParser.json());
personalRouter.route('/')

.get(Verify.verifyOrdinaryUser, function (req, res, next) {
    var mobile = req.decoded._doc.mobile;
    var Personal = database.create_database(mobile);
    Personal.find(req.query)
    .exec(function (err, personal) {
        if (err) next(err);
        res.json(personal);
    })
})

.post(Verify.verifyOrdinaryUser, function(req, res, next) {
    var mobile = req.decoded._doc.mobile;
    var Personal = database.create_database(mobile);
    Personal.create(req.body, function(err, personal) {
        if(err) next(err);
        console.log('Personal Record added!');
        var type = personal.type;
        var amount = personal.amount/100;
        res.writeHead(200, {
            'Content-Type': 'text/plain'
        });
        res.end('Added the '+type+' record of amount = '+amount);
    })
})

module.exports = personalRouter;

现在一切都运行良好的get和post路由器，直到我传递的值不是mongoose模式。例如。如果我在没有描述的情况下传递值，我的服务器将给出验证错误并崩溃。我尝试用throw替换下一个（错误）（错误的代码没有任何运气。我希望显示错误并防止服务器崩溃和关闭。请帮助我，我哪里出错？

使用mongoose发生验证错误时，节点服务器崩溃
