I have following models in django app:

models.py:

class Make(BaseModel):
    slug = models.CharField(max_length=32) #alfa-romeo
    name = models.CharField(max_length=32) #Alfa Romeo

    def __unicode__(self):
        return self.name

class Model(BaseModel):
    make = models.ForeignKey(Make)  #Alfa Romeo
    name = models.CharField(max_length=64) # line[2]
    engine_capacity = models.IntegerField()
    trim = models.CharField(max_length=128) # line[4]

And serializers.py:

from .models import Make,Model
from rest_framework import serializers


class MakeSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Make
        fields = ('url', 'slug', 'name')


class ModelSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Model
        fields = ('url', 'make', 'name', 'trim', 'engine_capacity')

and also views.py:

from rest_framework import viewsets
from rest_framework import filters
from rest_framework import generics

from .models import Make, Model
from .serializers import MakeSerializer, ModelSerializer


class MakeViewSet(viewsets.ModelViewSet):
    queryset = Make.objects.all()
    serializer_class = MakeSerializer
    filter_backends = (filters.DjangoFilterBackend,)

class ModelViewSet(viewsets.ModelViewSet):
    make = MakeSerializer
    queryset = Model.objects.all()
    serializer_class = ModelSerializer
    filter_backends = (filters.DjangoFilterBackend,)

What I need to to, I want to fetch all Models manufactured by specific make. How can I get all models with particular make foreign key using query params? And my 2nd question - can I filter results using queryparams to get models with specific engine_capacity?

One comment: It would be perfect, if I can to query results using something like this in url: /api/models/?make=ford where make is slug field in Make model

urls.py

url('^model/by/(?P<make>\w+)/$', ModelByMakerList.as_view()),

views.py

class ModelByMakerList(generics.ListAPIView):
    serializer_class = ModelSerializer

    def get_queryset(self):
        """
        This view should return a list of all models by
        the maker passed in the URL
        """
        maker = self.kwargs['make']
        return Model.objects.filter(make=maker)

For more info checkout the docs.

You can also use filtering with QUERY_PARAMS, but IMHO this looks better.
