Django-REST-Framework

Serializers
	* Notice that we're using hyperlinked relations in this case, with HyperlinkedModelSerializer. You can also use primary key and various other relationships, but hyperlinking is good RESTful design
	
	* HyperlinkedModelSerializer:
		class UserSerializer(serializers.HyperlinkedModelSerializer):
			class Meta:
				model = User
				fields = ('url', 'username', 'email', 'groups')
