ch6.25~ delete, search

1. Delete Videos

• 1. watch.pug 에 delete버튼 생성

a(href=`${video.id}/delete`) Delete Video →

• 2. videoRouter에 delete route생성

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

• 3. controller 에 deleteVideo 함수생성 & import, export 
• model.findByIdAndDelete() 

export const deleteVideo = async (req, res) => {
  const { id } = req.params;
  await Video.findByIdAndDelete(id);

  return res.redirect("/");
};

• delete, remove차이 >> 뭐쨌든 delete로 쓰삼 ㅇㅅㅇ

2. search

• Model.find({}).sort({}) 

const videos = await Video.find({}).sort({ createdAt: "desc" });

• search페이지 만들꺼임
  • 링크추가, globalRouter에 /search 추가, search함수생성, pug 생성
  •  

export const search = (req, res) => {
  return res.render("search", { pageTitle: "Search" });
};

================================
extends base.pug

block content 
    form(method="GET")
        input(placeholder="Search by title", name="keyword", type="text")
        input(type="submit", value="Search now")

 

• /:id >> req.params
• form post >> req.body
• form GET >> req.query 
  • keyword가 undefined인경우 생각해야함 >> 2가지케이스

export const search = async (req, res) => {
  const { keyword } = req.query;
  if (keyword) {
    const videos = await Video.find({
      title: keyword,
    });
    return res.render("search", { pageTitle: "Search", videos });
  }
  return res.render("search", { pageTitle: "Search" });
};
-----------------아니면--- let으로 --------------
export const search = async (req, res) => {
  const { keyword } = req.query;
  let videos = [];
  if (keyword) {
    videos = await Video.find({
      title: keyword,
    });
  }
  return res.render("search", { pageTitle: "Search", videos });
};

• search.pug 에 mixin부분 추가

include mixins/video

each video in videos    
        +video(video)

• 검색방식 개선하기 > 정규식추가
  • i : 대소문자 무시
  • ^ 앞에만 $ 끝에만

if (keyword) {
    videos = await Video.find({
      title: {
        $regex: new RegExp(`${keyword}$`, "i"),
      },
    });
  }
