Django_filters filter option not visible on browsable api

[Shekhar Nunia]

Hi,

I am following these https://github.com/encode/django-rest-framework/issues/4689, https://stackoverflow.com/questions/63741389/django-rest-framework-filter-not-working-the-filter-button-is-not-showing-on-br to see what I missed so that my filter not showing, sharing code snippet which was used

REST_FRAMEWORK = {

    "DEFAULT_FILTER_BACKENDS": ["django_filters.rest_framework.DjangoFilterBackend"],

}

class ProductListAPIView(generics.ListAPIView):

    serializer_class = ProductSerializer

    filterset_class = ProductFilter

    def get_queryset(self):

        return ProductService().get_products()

    def get(self, request, *args, **kwargs):

        response = super().get(request, *args, **kwargs)

        return send_response(

            data=response.data,

            status_code=response.status_code,

            message=ResponseMessages.DATA_FETCH_SUCCESS,

        )

class ProductFilter(django_filters.FilterSet):

    price_min = django_filters.NumberFilter(field_name="price", lookup_expr="gte")

    price_max = django_filters.NumberFilter(field_name="price", lookup_expr="lte")

    class Meta:

        model = Product

        fields = [

            "brand",

            "product_name",

            "lens_category",

            "price_min",

            "price_max",

        ]

INSTALLED_APPS = [

    "django.contrib.admin",

    "django.contrib.auth",

    "django.contrib.contenttypes",

    "django.contrib.sessions",

    "django.contrib.messages",

    "django.contrib.staticfiles",

    "django.contrib.postgres",

    "rest_framework",

    "products",

    "crispy_forms",

    "django_filters",

    "drf_yasg",

]

Django==4.2.4

django-crispy-forms==2.0

django-filter==23.2

djangorestframework==3.14.0

I tried to setup another basic new project with 1 model and in that case I was able to see filter button 

but this didn't work on my main project, can anyone help me understand what I missed on the above code snippet so that the filter not showing on browsable API even tho it's showing on swagger with all options.

I hope to get some help regarding this.

Thanks

I have not created a filterset before but I use this code in my API views, and I am always able to filter in browsable API.

filter_backends = [DjangoFilterBackend]
filterset_fields = ['x', 'y', 'z']

And in settings.py:

REST_FRAMEWORK = {

...
    'DEFAULT_FILTER_BACKENDS': ['django_filters.rest_framework.DjangoFilterBackend'],

...

... and these imports in your views.py:

from rest_framework import generics
from rest_framework import filters
from django_filters.rest_framework import DjangoFilterBackend
