I have a M2M relationship between Product and Purchase. What I am trying to achieve is when a purchase is made, to also fill the PurchasedProduct(the through model) model. But every time I send the data to the API and I try to access the products

ANSWER
Answered 2018-Nov-02 at 07:37Well, where to put business logic is always question hard to answer. You have multiple places where it can be - view, serializer, model or some other separate module/service.
All have pros and cons- you can find many articles on this topic.
But in your case, I would probably go with perform_create
of your view and I would create a method in the serializer which would update the price. If I needed to use the code to update price, I'd move to separate shared module and call it from there.
So let's say you use CreateModelMixin
or better ListCreateAPIView
