1. 더미 데이터를 json형태로 만듭니다.

   그 후 다음과 같이 넣어줍니다.

   const plant_level = JSON.parse(
         fs.readFileSync(`${path.resolve()}/_dummyData/plant_level.json`, 'utf-8')
       );
   

2. 더미 데이터를 넣고 싶은 부분만 주석처리를 풀어줍니다.

   await queryInterface.bulkInsert('plant_level', plant_level, {});
   

3. 터미널에서 다음 명령어를 입력합니다.

   sequelize db:seed:all

   <aside> 💡 sequelize 명령어가 에러난다면? npm i -g sequelize-cli 로 설치해줘야 합니다!
