How to programmatically provide `queryset` to PrimaryKeyRelatedField in DRF 3

Question

In order to have a non-readonly PrimaryKeyRelatedField, you are required to provide a queryset that contains valid options.

How can I properly populate that

Answer 1

View has a

self.request.user

attribute which you can then use to fetch user related queryset eg

queryset = Products.objects.get(customer=self.request.user)
