Views.py
class CountryViewSet(viewsets.ViewSet):
serializer_class = CountrySerializer
pagination_class = LimitOffsetPagination
def list(self,request):
try:
country_data = Country.objects.all()
country_serializer = CountrySerializer(country_data,many=True)
return Response(
data = country_serializer.data,
content_type='application/json',
)
except Exception as ex:
return Response(
data={'error': str(ex)},
content_type='application/json',
status=status.HTTP_400_BAD_REQUEST
)
Settings.py 我添加了
'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.LimitOffsetPagination',
在我的urls.py
中router = routers.DefaultRouter(trailing_slash=False)
router.register(r'country', CountryViewSet, base_name='country')
urlpatterns = [
url(r'^', include(router.urls)),
]
当我尝试使用此网址http://192.168.2.66:8001/v1/voucher/country时,它会返回所有数据。
但是当我尝试使用此网址http://192.168.2.66:8001/v1/voucher/country/?limit=2&offset=2
时但它返回404错误。 我是django的新手。请帮助我:)

使用ModelViewSet
而不是ViewSet
。同时删除列表功能,它会自动发送响应。
from rest_framework.pagination import LimitOffsetPagination
class CountryViewSet(viewsets.ModelViewSet):
"""
A simple ViewSet for viewing and editing country.
"""
queryset = Country.objects.all()
serializer_class = CountrySerializer
pagination_class = LimitOffsetPagination
ModelViewSet类提供的操作是.list(), .retrieve(),. create(),. update(),. partial_update()和.destroy()。

在你的settings.py
中REST_FRAMEWORK = {
'PAGE_SIZE': 10,
# 'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.LimitOffsetPagination',
}
更新2
或者,您可以使用paginate_queryset
和get_paginated_response
def list(self,request):
country_data = Country.objects.all()
page = self.paginate_queryset(country_data)
if page is not None:
serializer = self.get_serializer(page, many=True)
return self.get_paginated_response(serializer.data)
serializer = self.get_serializer(country_data, many=True)
return Response(serializer.data)
