DRF 2-4 update, delete, 상세페이지

GET과 POST에서는 별도의 url이 필요 없지만
앞으로는 필요하다.

# articles/views.py

@api_view(['GET', 'PUT', 'DELETE'])
def article_view(request, article_id):
    return Response(article_id)

# articles/urls.py

from django.urls import path
from articles import views

urlpatterns = [
    path('index', views.index, name="index"),
    path('<int:article_id>/', views.article_view, name="article_view"),
]

다음과 같이 추가하면

# articles/views.py

@api_view(['GET', 'PUT', 'DELETE'])
def article_view(request, article_id):
    if request.method == 'GET':
        # return Response(article) 이렇게는 할 수 없고
        # article = Article.objects.get(id=article_id) # 1004를 저장
        article = get_object_or_404(Article, id=article_id)
        serializer = ArticleSerializer(article)
        return Response(serializer.data)

오류 처리도 매끄럽게 되도록.

# articles/views.py

@api_view(['GET', 'PUT', 'DELETE'])
def article_view(request, article_id):
    if request.method == 'GET':
        # return Response(article) 이렇게는 할 수 없고
        # article = Article.objects.get(id=article_id) # 1004를 저장
        article = get_object_or_404(Article, id=article_id)
        serializer = ArticleSerializer(article)
        return Response(serializer.data)
    elif request.method == 'PUT':
        # 위 상세페이지처럼, 복사해서 가져와서 수정을 해줘야 한다.
        article = article = get_object_or_404(Article, id=article_id)
        serializer = ArticleSerializer(article, data=request.data) 
        # (원래data:읽기, 나중에들어온data) 앞의data를 뒤data로 바꾸어주는 것.
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)

PUT이 생겼고 수정이 가능하다.
