I have the following code which doesn't work:
In models.py:
class Unit(models.Model):
unit_name = models.CharField(max_length=255)
In views.py:
class MultipleFieldLookupMixin(object):
"""
Apply this mixin to any view or viewset to get multiple field filtering
based on a `lookup_fields`
Great, this worked for me. Thanks Alan.

Yes, I believe the default search keyword is `search`. It searches for a
keyword match across all the `search_fields`. I believe that's what you
indicated. If you want to search individual fields with a variety of
possible relationships, take a look at `DjangoFilterBackend`.

Alan, thanks. With this approach do I have to explicitly define URLs in
urls.py or are these generated? For the above, would the URL look like the
following?
localhost/api/units?search=string
Where string is the literal string to be searched?
If this is the case, how does it know whether I want
Asad:
I believe what you want should work with SearchFilter. Something like this:
from rest_framework.filters import SearchFilter
class UnitViewSet(viewsets.ReadOnlyModelViewSet):
serializer_class = UnitSerializer
queryset = Unit.objects.all()
filter_backends = (SearchFilter, )
Alan, appreciate your input. Basically, I want to be able to retrieve units
based on either a primary key or other attribute. Is this possible using
filtering if URLs are being defined using routers?

Thanks Jason. Now, the get_object function in class
MultipleFieldLookupMixin is actually being called but it's throwing an
error as follows:
if self.kwargs[field]: # Ignore empty fields.
KeyError: 'unit_name'
The ViewSet is defined as follows:
class UnitViewSet(CountModelMixin,
This seems like you are reinventing SearchFilter. Maybe I’m
misunderstanding.

Due to python's method resolution order, you need to have mixins first in
the class inheritance order. Specifically
class UnitViewSet(MultipleFieldLookupMixin, viewsets.ReadOnlyModelViewset):
