基于Mixin类重构视图类

from snippets.models import Snippet
from snippets.serializers import SnippetSerializer
from rest_framework import mixins
from rest_framework import generics

class SnippetList(mixins.ListModelMixin,
                  mixins.CreateModelMixin,
                  generics.GenericAPIView):
    # 雷打不动，必须的
    queryset = Snippet.objects.all()

• CreateModelMixin: 定义了创建一个序列对象的方法create(self, request, *args, **kwargs)，保存方法perform_create(self, * * * serializer)，成功获取请求头的方法：get_success_headers(self, data)
• ListModelMixin： 定义了一个获取查询集的方法, many=True：list(self, request, *args, **kwargs)
• RetrieveModelMixin: 定义了一个检索方法，retrieve(self, request, *args, **kwargs)
• UpdateModelMixin： 更新一个模型实例，update(self, request, *args, **kwargs)
• DestroyModelMixin： 删除一个模型实例，方法destroy(self, request, *args, **kwargs)
