第一章：前菜——回忆一下，那些年我们写废的视图函数

嘿，Django老铁，下面这个场景你是不是贼熟悉？

你想给一个Article模型搞一套完整的REST API，包含列表、详情、创建、更新、删除。于是你打开views.py，开始疯狂输出：

# 曾经的你，是一个勤劳的“码农”
from rest_framework import status
from rest_framework.decorators import api_view
from rest_framework.response import Response
from .models import Article
from .serializers import ArticleSerializer

@api_view(['GET', 'POST'])
def article_list(request):
    if request.method == 'GET':
        articles = Article.objects.all()
        serializer = ArticleSerializer(articles, many=True)
        return Response(serializer.data)
    elif request.method == 'POST':
        serializer = ArticleSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

@api_view(['GET', 'PUT', 'DELETE'])
def article_detail(request, pk):
    try:
        article = Article.objects.get(pk=pk)
    except Article.DoesNotExist:
        return Response(status=status.HTTP_404_NOT_FOUND)

    if request.method == 'GET':
        serializer = ArticleSerializer(article)
        return Response(serializer.data)
    elif request.method == 'PUT':
        serializer = ArticleSerializer(article, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
    elif request.method == 'DELETE':
        article.delete()
        return Response(status=status.HTTP_204_NO_CONTENT)

然后，你再屁颠屁颠地
