[Django rest-framework] 4-Class-based Views

基于类的api视图

能让代码看起来更干净明朗

 

• 将api改为基于类的视图

  from snippets.models import Snippet
  from snippets.serializers import SnippetSerializer
  from django.http import Http404
  from rest_framework.views import APIView
  from rest_framework.response import Response
  from rest_framework import status
  
  
  class SnippetList(APIView):
      """
      List all snippets, or create a new snippet.
      """
      def get(self, request, format=None):
          snippets = Snippet.objects.all()
          serializer = SnippetSerializer(snippets, many=True)
          return Response(serializer.data)
  
      def post(self, request, format=None):
          serializer = SnippetSerializer(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)
  

   

• url文件使用as_view

  from django.conf.urls import url
  from rest_framework.urlpatterns import format_suffix_patterns
  from snippets import views
  
  urlpatterns = [
      url(r'^snippets/$', views.SnippetList.as_view()),
      url(r'^snippets/(?P<pk>[0-9]+)/$', views.SnippetDetail.as_view()),
  ]
  
  urlpatterns = format_suffix_patterns(urlpatterns)
