Comment by Emanuele Sarracino on "Django Service Layers: Beyond Fat Models vs. Enterprise Patterns"

That's a good question. I haven't worked with forms in years but I can say a couple of things about serializers.

In HackSoft's styleguide they recommend using serializers for data validation/presentation only. In their examples, the serializers are nested in the view class and don't interact with the service layer. (github.com/HackSoftware/Django-Styleguide)

At my company, we ended up calling the service functions from inside the serialisers' create and update methods (django-rest-framework.org/api-guide/serializers). This allowed us to make better use of the GenericAPIView classes (django-rest-framework.org/api-guide/generic-views).
