You need to add lookup_field in view class. Suppose, you want to get user by username you need to add lookup_field = 'username'.

Example:

from django.contrib.auth.models import User
from django.shortcuts import get_object_or_404
from myapps.serializers import UserSerializer
from rest_framework import viewsets
from rest_framework.response import Response

class UserViewSet(viewsets.ViewSet):

    lookup_field = 'username'

    def list(self, request):
        queryset = User.objects.all()
        serializer = UserSerializer(queryset, many=True)
        return Response(serializer.data)

    def retrieve(self, request, username=None):
        queryset = User.objects.all()
        user = get_object_or_404(queryset, username=username)
        serializer = UserSerializer(user)
        return Response(serializer.data)

Now your url will be

url(r'^users/$', UserViewSet.as_view({'get': 'list'})),
url(r'^users/(?P[a-zA-Z0-9]+)$', UserViewSet.as_view({'get': 'retrieve'})),

Now http://127.0.0.1:8000/users/ will return all users and http://127.0.0.1:8000/users/username will return particular user details.
