Question

大家好，我写一个简单的博客我可以保存和编辑博客中的文章，但是保存和编辑后无法重定向到管理页面而且由于以下原因，我的ejs模板引擎出现错误：我应该再次刷新以登录以查看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：
