1. FBV > CBV로 바꾸기

      

      

      

    
    

      <code />
    
## articles/views.py
...
from rest_framework.views import APIView

class ArticleList(APIView):
    def get(self, request, format=None):
        articles = Article.objects.all()
        serializer = ArticleSerializer(articles, many=True)
        return Response(serializer.data, status=status.HTTP_200_OK)

    def post(self, request, format=None):
        serializer = ArticleSerializer(data = request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        else:
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

class ArticleDetail(APIView):
    def get(self, request, article_id, format=None):
        article = get_object_or_404(Article, id=article_id)
        serializer = ArticleSerializer(article)
        return Response(serializer.data)

    def put(self, request, article_id, format=None):
        article = get_object_or_404(Article, id=article_id)
        serializer = ArticleSerializer(article, data = request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_200_OK)
        else:
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
    
    def delete(self, request, article_id, format=None):
        article = get_object_or_404(Article, id=article_id)
        article.delete()
        return Response("삭제 완료", status=status.HTTP_204_NO_CONTENT)

기존에 있던 articleAPI, articleDetailAPI는 삭제하자

      

      

      

    
    

      <code />
    
## articles/urls.py
urlpatterns = [
    path('', views.ArticleList.as_view(), name='index'),
    path('<int:article_id>/', views.ArticleDetail.as_view(), name='article_view'),
]

2. CBV에서 Swagger post 사용하기

      

      

      

    
    

      <code />
    
## article/views.py
...
from drf_yasg.utils import swagger_auto_schema

class ArticleList(APIView):
    def get(self, request, format=None):
        articles = Article.objects.all()
        serializer = ArticleSerializer(articles, many=True)
        return Response(serializer.data, status=status.HTTP_200_OK)

    @swagger_auto_schema(request_body=ArticleSerializer)
    def post(self, request, format=None):
        serializer = ArticleSerializer(data = request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        else:
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
