django rest framework filter

django, django-filter, django-rest-framework, python

Solution

You need to define filter backend and all related fields you're planning to filter on:

class EstablecimientoViewSet(viewsets.ModelViewSet):
    filter_backends = (filters.DjangoFilterBackend,)
    filter_fields = ('categoria', 'categoria__titulo',)

example:

URL?categoria__titulo=Categoria 1

Problem

I'm working with API made from Django rest framework, I am trying to make a filter to a JSON This is my `serializers.py` file ``` from rest_framework import serializers from .models import Establecimiento,Categoria,Ciudad,Zona import django_filters class EstablecimientoSerializer(serializers.ModelSerializer): class Meta: model = Establecimiento depth = 1 fields = ('nombre', 'ciudad', 'categoria', 'direccion', 'telefono', 'precioMinimo', 'precioMaximo',) ``` and this my `views.py` file ``` from rest_framework import viewsets from .serializers import EstablecimientoSerializer, CategoriaSerializer from models import * from rest_framework import filters from rest_framework import generics class EstablecimientoViewSet(viewsets.ModelViewSet): queryset = Establecimiento.objects.all() serializer_class = EstablecimientoSerializer filter_fields = ('categoria',) ``` Then in the `EstablecimientoViewSet` class, I put a `filter_fields = ('categoria',)` to filter the url's API with the category field If I add the filter to the query parameters, the result set does not change, it shows all data unfiltered. ``` ...establecimiento?establecimiento=bar ``` How can I make this filter about this model?
