교재 p610 makemigrations 질문드립니다.

안녕하세요, 작가님.

집필하신 교재 재밌게 잘 보고 있습니다.

교재를 보던 중 p610, 'sudo docker-compose exec web python manage.py makemigrations' 부분에서 계속해서

오류가 발생하여 여쭤봅니다.

현재 디렉토리에 존재하는 폴더들은 아래와 같습니다.

.env.dev   .env.prod.db  .gitignore  README.md  _static  django_prj              docker-compose.yml  nginx             single_pages
.env.prod  .git          Dockerfile  _media     blog     docker-compose.dev.yml  manage.py           requirements.txt

.env.prod 파일 내부 내용입니다.

DEBUG=0
SECRET_KEY=[본인의 secret key]
DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 [공인 IP] [::1]
SQL_ENGINE=django.db.backends.postgresql
SQL_DATABASE=do_it_django_prod
SQL_USER=do_it_django_db_user
SQL_PASSWORD=do_it_django_db_password
SQL_HOST=db
SQL_PORT=5432
DATABASE=postgres

.env.prod.db 파일 내부 내용입니다.

POSTGRES_USER=do_it_django_db_user
POSTGRES_PASSWORD=do_it_django_db_password
POSTGRES_DB=do_it_django_prod

위 두 파일의 내용과 관련이 있나 싶어 노랗게 하이라이트한 부분 재확인 해보았는데 결과는 동일했습니다.

책에 나온 user와 password를 그대로 활용했습니다.

p610의 'sudo docker-compose exec web python manage.py makemigrations'를 실행하자

아래와 같은 에러메시지가 발생했습니다.

The above exception was the direct cause of the following exception:

do_it_django_db_user와 관련해서 파일 간 연결에 문제가 있어서 그런 거 같은데

작가님의 의견을 여쭙고 싶습니다.

감사합니다.
