 * `queryset` - The queryset that should be used for returning objects from this view.  Typically, you must either set this attribute, or override the `get_queryset()` method.
 * `serializer_class` - The serializer class that should be used for validating and deserializing input, and for serializing output.  Typically, you must either set this attribute, or override the `get_serializer_class()` method.
-* `lookup_field` - The field that should be used to lookup individual model instances.  Defaults to `'pk'`.  The URL conf should include a keyword argument corresponding to this value.  More complex lookup styles can be supported by overriding the `get_object()` method.  Note that when using hyperlinked APIs you'll need to ensure that *both* the API views *and* the serializer classes use lookup fields that correctly correspond with the URL conf.
+* `lookup_field` - The model field that should be used to for performing object lookup of individual model instances.  Defaults to `'pk'`.  Note that when using hyperlinked APIs you'll need to ensure that *both* the API views *and* the serializer classes set the lookup fields if you need to use a custom value.
+* `lookup_url_kwarg` - The URL keyword argument that should be used for object lookup.  The URL conf should include a keyword argument corresponding to this value.  If unset this defaults to using the same value as `lookup_field`.
