django.db.utils.ProgrammingError: (1146, "Table 'django_insta.products_category' doesn't exist") 에러 해결

python manage.py shell

에서 Menu.objects.all() 이라는
디비에 등록된 컬럼을 보여달라는 명령어에

rammingError: (1146, "Table 'django_insta.products_category' doesn't                                         exist")

이런 에러가 뜬다면

models.py 변경 후 마이그레이션을 안해서 그렇다

그래서 마이그레이션을 시도하지만 에러가 난다..

(first)
ubuntu@ubuntu:~/miniconda3/mysite$ python manage.py makemigrations products/
No installed app with label 'products/'.

하지만 또 다른 통과 방법을 찾았다
(first) ubuntu@ubuntu:~/miniconda3/mysite$ ./manage.py makemigrations
