ExpressJS链接到更新内容

Question

我正在尝试通过我的编辑器更新我的内容，但我想知道我应该修改哪些应用程序以便能够执行此操作。我有一种感觉，它是通过路径文件，但想知道我是否应该在我的视图中使用超链接方法，以便能够使用我想要编辑的内容生成我的视图。

这是我的路线档案：

var express = require('express');
var router = express.Router();
var passport = require('passport');
var blogDB = require('../config/blogDB.js');
var Blogpost = require('./models/blogModel.js');
var paginate = require('express-paginate');
var http = require('http');
var path = require('path');
var aws = require('aws-sdk');

var AWS_ACCESS_KEY = process.env.AWS_ACCESS_KEY;
var AWS_SECRET_KEY = process.env.AWS_SECRET_KEY;
var S3_BUCKET = process.env.S3_BUCKET;

//index 
router.use(paginate.middleware(10, 50));




    router.route('/') 


        // START GET method
        .get(function(req, res, next) {

            Blogpost.paginate({}, req.query.page, req.query.limit, function(err, pageCount, blogpost, itemCount) {




                if (err) return next(err)

                        if (err)
                            res.send(err);




                        res.format({
                            html: function() {
