[멋쟁이사자처럼 11기] 4회차: Django 실습

Model

 

데이터베이스

- 관계형 데이터 베이스: 테이블

 

장고ORM

- SQL문을 안쓰고도 데이터 조작 및 관리 가능하게 함

 

Class와 Table

- Class = Table

 

models.py의 변경사항을 감지하여 파일로 생성:

python manage.py makemigrations

 

makemigrations에서 생성된 파일을 DB에 적용:

python manage.py migrate

 

admin 아이디/비번 설정:

python manage.py createsuperuser
