django rest framework ViewSets & Routers

Using viewsets

views.py

from rest_framework import viewsets
from rest_framework import mixins
from rest_framework.pagination import PageNumberPagination


class MyPagination(PageNumberPagination):
    """分页"""
    page_size = 10
    page_size_query_param = "size"
    max_page_size = 50
    page_query_param = "page"


class DrugBidViewSets(viewsets.GenericViewSet,mixins.ListModelMixin):
    queryset = DrugBidModel.objects.all().order_by("id") # queryset = DrugBidModel.objects.all()
    serializer_class = DrugBidSerializers
    pagination_class = MyPagination

　　　

问题描述：UnorderedObjectListWarning: Pagination may yield inconsistent results with an unordered object_list

这个是因为django，查询出来多条记录时，默认是无序排列的，所以 每查询一次 分页的 list 都是不一样的，因此加一个排序

Using Router

urls.py

from rest_framework.routers import DefaultRouter

from drug import views


router = DefaultRouter()
router.register(r"drugbid",views.DrugBidViewSets)

urlpatterns = [
    path('', include(router.urls)),
]
