delete Video

1. route

delete는 get으로 작동한다는 것을 명심한다.

videoRouter
  .route('/:id([0-9a-f]{24})/delete')
  .all(protectorMiddleware)
  .get(deleteVideo)

2. controller

export const deleteVideo = async (req, res) => {
  const { id } = req.params
  const {
    user: { _id },
  } = req.session
  const video = await Video.findById(id)
  if(!video){
    return res.render('404', { pageTitle: 'Video not found' })
  }
  if (String(video.owner) !== String(_id)) {
    return res.status(400).redirect('/')
  }
  await Video.findByIdAndDelete(id)
  return res.redirect('/')
}
///findByIdAndDelete를 사용하면 한번에 처리할 수 있다.
///defensive는 자동적으로 해 주어야함.

3. pug

extends base.pug

//- block head 
//-     title Watch | JmTube

block content 
    video(src='/'+video.fileUrl, controls, width=600, height=500)    
    h1=video.title
    div
        p=video.description
        small=video.createdAt
    
    div 
        small=video.owner.email 
        br
        small Uploaded by 
                a(href=`/users/${video.owner._id}`) #{video.owner.username}
    each hashtag in video.hashtags 
            li=hashtag
    h3 #{video.views} #{video.views === 1 ? "view" : "views"}
    if String(video.owner._id) === String(loggedInUser._id)
        a(href=`${video.id}/edit`) Edit Video →
        br
        a(href=`${video.id}/delete`) Delete Video →
///path를 적어주면, 위 path의 controller(deleteVideo)가 작동함.
