업데이트가 꼬였을 때 발생하는 오류이다.

python manage.py showmigrations를 통해 조회한다.

꼬여있다.

이를 위해서는?

프로젝트의 db.sqlite3 파일을 지워서, migration history 전체를 날려버리면 된다.

날린 후, python manage.py showmigrations migration history를 보니,

정말 깔끔해졌다.

이후 python manage.py migrate 가 잘 실행된다.😎

1), 2)를 비교하면 크게 social_django가 추가되지 않을 것을 볼 수 있다.

이럴 경우, git에서 문제가 있는지 migrate가 실행되었는지 알아봐야 한다.

 

sourcetree에서 확인한 결과

병합 과정에 겹친 소스가 있어 git push heroku master가 되지 않았던 것이다.

위부분을 수정해주면 migrate한 후 migration을 확인할 시 1), 2)가 똑같은 결과로 출력될 것이다.
