0. 앱 실행하기 위해서!

- 앱을 생성한다.

django-admin startapp 앱이름

- 전체 urls.py와 해당앱의 urls.py에 추가한다.

urlpatterns = [
    # 새로만들어준 app의 url 기본 path설정해주기
    path('member/', include('member.urls')),
   ...
]

- 앱의 urls.py는 없으므로 새로 만들어줄 것! (views.py의 method와 연결해준다.)

from django.urls import path
from .views import SignUp,Login

urlpatterns = [
    path('join/',SignUp.as_view(), name="join"), # name을 붙이는 이유는 html에서 불러오기 위함.
    path('login/',Login.as_view(), name="login")
]

- settings에 추가한다.

INSTALLED_APPS = [
  	...
    '{앱이름}.apps.{클래스이름}Config' # 앱 추가
]

* 데이터베이스를 이용하기 위해서 사용하는 명령어 두 가지 

  makemigrations, migrate

(venv) C:\Users\user\PycharmProjects\DjangoProject\insta>python manage.py makemigrations
Migrations for 'member':
  member\migrations\0001_initial.py

(venv) C:\Users\user\PycharmProjects\DjangoProject\insta>python manage.py migrate

- views에서 작동하는 코드를 작성한다.

- template 에서 html 코드를 작성한다.

- 로그인 기능을 위해 django-rest-auth를 설치한다. (결과적으로는 필요하지는 않았다.)
