django-simplefilters

Plain Django

While django-simplefilters were built with Django Rest Framework in mind it's really easy to use it with plain Django views too.

Filterset

Let's define our filtering as usual.

import simplefilters as filters


class Todo(filters.FilterSet):

    @filters.CharFilter(many=True)
    def filter_status(self, qs, values):
        return qs.filter(status__in=values)

    @filters.DateTimeFilter()
    def filter_modified_after(self, qs, value):
        return qs.filter(modified_at__gte=value)

Django view 

from . import filtersets
from . import models
from django.http import JsonResponse
import simplefilters as filters


def todo_list_view(request):
    queryset = models.Todo.objects.all()
    fs = filtersets.Todo()
    qs = fs.perform_filtering_for_query_params(queryset, request.GET)
    return JsonResponse([{
        "id": todo.id,
        "title": todo.title,
    } for todo in qs], safe=False)

Call filterset directly

It is possible to use simplefilters out of request-response cycle.

from . import filtersets
from . import models
from . import serializers
from rest_framework.decorators import api_view
from rest_framework.response import Response
from rest_framework.viewsets import ModelViewSet
import simplefilters as filters


def get_todos(params):
    queryset = models.Todo.objects.all()
    fs = filtersets.Todo()
    return fs.perform_filtering_for_query_params(queryset, {'status': ['active', 'archived']})
