Question

我写了一个简单的博客。我可以保存并编辑博客中的文章，但是保存并编辑后，无法重定向到管理页面。另外，由于这个原因，我的ejs模板引擎出现错误：我必须再次刷新才能登录才能看到admin_page

这是我的路线代码：

const express = require('express')
    const Article = require('../models/article')
    const article = require('../models/article')
    const router = express.Router()
    router.get('/new', (req, res) => {
        res.render('admin/article/new', { article: new Article() })
    
    })
    router.get('/edit/:id', async(req, res) => {
        const article = await Article.findById(req.params.id)
        res.render('admin/article/edit', { article: article })
    })
    
    router.get('/:slug', async(req, res) => {
        const article = await Article.findOne({ slug: req.params.slug })
        if (article == null) {
            res.redirect('/')
        } else {
            res.render('admin/article/show', { article: article })
        }
    })
    
    router.post('/', async(req, res, next) => {
        req.article = new Article()
        next()
    }, saveArticleAndRedirect('new'))
    
    router.put('/:id', async(req, res, next) => {
        req.article = await Article.findById(req.params.id)
    
        next()
    }, saveArticleAndRedirect('edit'))
    
    router.delete('/:id', async(req, res) => {
        await Article.findByIdAndDelete(req.params.id)
        res.render('admin/article/index_admin', { articles: articlee() })
    })
    
    function articlee() {
        return Article.find().sort({ createdAt: 'desc' })
    }
    
    function saveArticleAndRedirect(path) {
        return async(req, res) => {
            const article = req.article
            article.title = req.body.title
            article.description = req.body.description
            article.markdown = req.body.markdown
            try {
                article = await article.save().then(() => {
                    res.render('admin/article/index_admin', { articles: articlee() })
                        // res.redirect('/admin/article/index_admin')
                })
    
    
            } catch (e) {
                res.render(`admin/article/${path}`)
            }
    
            // function articlee() {
            //     return Article.find().sort({ createdAt: 'desc' })
        }
    }
    
    
    
    module.exports = router

这是管理员页面代码：

                        <div class="card-text mb-2">
                            <%=article.description %>

                        <a href="/admin/article/<%= article.slug %>" class="btn btn-primary">Read More</a>

                            <button type="submit" class="btn btn-danger ">DELETE</button>
                        </form>
                    </div>
                </div>
                <% }) %>
        </div>
    </body>
    
    </html>

为什么ejs模板引擎找不到我的文章？
