REST framwork之分页器,路由器,响应器

一 REST framwork分页器:

from rest_framework.pagination import PageNumberPagination,LimitOffsetPagination

class PNPagination(PageNumberPagination):
        page_size = 1    
        page_query_param = 'page'
        page_size_query_param = "size"
        max_page_size = 5

class BookViewSet(viewsets.ModelViewSet):

    queryset = Book.objects.all()
    serializer_class = BookSerializers
    def list(self,request,*args,**kwargs):

        book_list=Book.objects.all()
        pp=LimitOffsetPagination()
        pager_books=pp.paginate_queryset(queryset=book_list,request=request,view=self)
        print(pager_books)
        bs=BookSerializers(pager_books,many=True)

        #return Response(bs.data)
        return pp.get_paginated_response(bs.data)

 

二 路由器:

在view视图中我们已经将代码进行最大化的简化,但是有一个问题就是我们的urls 中不得不进行传参,以区别不同的GET请求,分别为:Retrieve与List

    url(r'^authors/$', views.AuthorModelView.as_view({"get": "list", "post": "create"})),
    url(r'^authors/(?P<pk>\d+)/$',views.AuthorModelView.as_view({"get": "retrieve", "put": "update", "delete": "destroy"})),

 

使用了REST framwork路由器:

 

三 响应器:
