🌱mongoDB:: Array로 find?

이상한(?)걸 발견했다.

 

게시글 북마크 기능 구현 중 북마크 스키마 자체를 없애고 유저 안의 칼럼으로 쌓이도록 해달라는 요청을 받았다.

 

services/users.js

getBookmark = async(nickName) => {
  let result = []
  const getBookmark = await this.usersRepository.getBookmark(nickName);
  console.log("getBookmark", getBookmark)  //여기서는 nickName에 해당하는 유저의 정보 찾아와짐
  const GetBookmark = getBookmark.map((userInfo) => userInfo.bookmark)  //위의 유저정보에서 bookmark만 map
  console.log("GetBookmark", GetBookmark)

  for (let i = 0; i < GetBookmark.length; i++){
    console.log(GetBookmark[0])
    const AllgetBookmark = await this.usersRepository.AllgetBookmark(GetBookmark[i])
    console.log("AllgetBookmark", AllgetBookmark)

    if(AllgetBookmark.length === 0) {
      const err = new Error('postsService Error');
      err.status = 200
      err.message = "등록된 게시물이 없습니다."
      throw err
    } else if(AllgetBookmark.length !== 0){
      result.push(AllgetBookmark)
    }
    console.log(AllgetBookmark)
  }

  return result
}

console;

그니까 저 배열([ '6386245b9e4f7e314551c053', '6386212f9e4f7e314551c01a' ]) 상태로 repo로 넘어간다.

postId [ '6386245b9e4f7e314551c053', '6386212f9e4f7e314551c01a' ]

배열로 잘 넘어왔는데

 

배열로 잘 찾아진다 ........???????????

배열 그대로 Posts에서 postId값으로 잘 찾아서 배열로 다시 잘 뱉어준다.

몽고디비는.... 신기하다........
