rest_framework中有五大基础接口：get_list（获得多条数据），get_one（获得一条数据），post_one（添加一条数据），put_one（修改一条数据），delete_one（删除一条数据）

五大接口基础实现

from rest_framework.views import APIView from rest_framework.response import Response from app import models, objson class Books(APIView): # 请求地址：/books/ def get(self, request, *args, **kwargs): book_list = models.Book.objects.all() book_data = objson.BookJson(book_list, many=True).data return Response({ 'status': 0, 'msg': 'ok', 'results': book_data }) # 请求地址：/books/ 参数：{"name": "红楼梦","price": "66.66","author": [1]} def post(self, request, *args, **kwargs): book_json = objson.BookJson(data=request.data) if book_json.is_valid(): book_json.save() return Response({ 'status': 0, 'msg': 'ok', 'results': book_json.data }) return Response({ 'status': 1, 'msg': book_json.errors, }) class Book(APIView): # 请求地址：/book/1/ def get(self, request, pk, *args, **kwargs): book = models.Book.objects.filter(pk=pk).first() book_data = objson.BookJson(book).data return Response({ 'status': 0, 'msg': 'ok', 'results': book_data }) # 请求地址：/book/2/ 参数：{"name": "红楼梦","price": "88.88","author": [1]} def put(self, request, pk, *args, **kwargs): book = models.Book.objects.filter(pk=pk).first() book_json = objson.BookJson(data=request.data, instance=book) if book_json.is_valid(): book_json.save() return Response({ 'status': 0, 'msg': 'ok', 'results': book_json.data }) return Response({ 'status': 1, 'msg': book_json.errors, }) # 请求地址：/book/2/ def delete(self, request, pk, *args, **kwargs): deleted, _ = models.Book.objects.filter(pk=pk).delete() if deleted != 0: return Response({ 'status': 2, 'msg': 'delete success', }) return Response({ 'status': 1, 'msg': 'delete failed', })

视图模块：ModelViewSet，实现五大接口

# views.py from rest_framework.viewsets import ModelViewSet from app import models, objson class Books(ModelViewSet): queryset = models.Book.objects serializer_class = objson.BookJson class Book(ModelViewSet): queryset = models.Book.objects serializer_class = objson.BookJson lookup_field = 'pk' # urls.py from app import views urlpatterns = [ # ... url(r'^books/', views.Books.as_view({'get': 'list', 'post': 'create'})), url(r'^book/(?P<id>\d+)/', views.Book.as_view({'get': 'retrieve', 'put': 'update', 'delete': 'destroy'})), ]

项目开发中的具体使用，可以再原有的五大接口上进行无限的扩展或者直接重写五大接口

# views.py from rest_framework.viewsets import ModelViewSet from rest_framework.response import Response from app import models, objson class BookView(ModelViewSet): def get_list(self, request, *args, **kwargs): book_list = models.Book.objects.all() book_data = objson.BookJson(book_list, many=True).data return Response({ 'status': 0, 'msg': 'ok', 'results': book_data }) # urls.py from app import views urlpatterns = [ # ... url(r'^books/', views.BookView.as_view({'get': 'get_list'})), ]

路由模块

from app import views urlpatterns = [ # CBV传统 url(r'^books/', views.Books.as_view()), ] urlpatterns = [ # CBV路由的函数分发 url(r'^books/', views.BookView.as_view({'get': 'get_list'})), ]
