Pagination and Filtering

[Thiago Mambretti]

Hi all,

Is it possible to use the default pagination backend along with the following filters?

'django_filters.rest_framework.DjangoFilterBackend',
'rest_framework.filters.SearchFilter',
'rest_framework.filters.OrderingFilter',

I'm using a ModelViewSet and the API only when I have only the pagination or the filters activated.

There's no mention on anything about it on the docs so came here for help.

Thanks,

Hi,

I can’t think of a reason why they wouldn’t work in particular if the documentation doesn’t says otherwise.

Any specific issue that makes you think they don’t ?

This looks more like you’ve set a list for pagination class for that view.

What does your view looks like ?

Xavier,

My views are pretty simple!

from __future__ import unicode_literals

import django_filters
from rest_framework import viewsets

from .models import Country, State, City
from .serializers import CountrySerializer, StateSerializer, CitySerializer


class CountryViewSet(viewsets.ModelViewSet):
    queryset = Country.objects.all()
    serializer_class = CountrySerializer
    filter_fields = ['name', 'code']
    search_fields = ['name', 'code']
    ordering_fields = ['name', 'code']


class StateViewSet(viewsets.ModelViewSet):
    queryset = State.objects.all()
    serializer_class = StateSerializer
    filter_fields = ['name', 'code', 'country']
    search_fields = ['name', 'code']
    ordering_fields = ['name', 'code', 'country']


class CityViewSet(viewsets.ModelViewSet):
    queryset = City.objects.all()
    serializer_class = CitySerializer
    filter_fields = ['name', 'code', 'state']
    search_fields = ['name', 'code']
    ordering_fields = ['name', 'code', 'state']
