Question

我正在创建一个对象，并且正在创建一个包含到EJS的mongoDB数据的对象，但是奇怪的是该对象未定义，我该如何处理？

pinjam.js

const express = require('express')
const router = express.Router()
const Pinjam = require('../models/pinjam.model')

router.get('/', async (req, res) => {
  const pinjams = await Pinjam.find()
  res.render('index', {
    pinjams
  })
})

router.post('/add', async (req, res, next) => {
  try {
    const pinjam = new Pinjam(req.body)
    await pinjam.save()
    res.redirect('/')
  } catch (err) {
    console.log(err)
    next()
  }
})

router.get('/turn/:id', async (req, res, next) => {
  let {
    id
  } = req.params
  const pinjam = await Pinjam.findById(id)
  pinjam.status = !pinjam.status
  await pinjam.save()
  res.redirect('/')
})


router.get('/edit/:id', async (req, res, next) => {
  const pinjam = await Pinjam.findById(req.params.id)
  console.log(pinjam)
  res.render('edit', {
    pinjam
  })
})

router.post('/edit/:id', async (req, res, next) => {
  const {
    id
  } = req.params
  await Pinjam.update({
    _id: id
  }, req.body)
  res.redirect('/')
})

router.get('/delete/:id', async (req, res, next) => {
  let {
    id
  } = req.params
  await Pinjam.remove({
    _id: id
  })
  res.redirect('/')
})


module.exports = router

index.ejs

                <% } %

这是错误

我制作了2个具有相同内容的文件夹，第一个用于测试，并且在该项目中成功，并且发生了错误。我需要帮助！
