Description
Django don´t have an obvious way to avoid N+1 queries during objects serialization and it is easy to miss the right way in large projects.
This talk aims to show how I joined a project with a rudimentary serialization solution and improved it to be able to handle serializations without causing N+1 queries by accident, using django-qserializer (I'm the author).
I will discuss other solutions, how to do that with plain Django, how DRF do the same thing, how other libs can contribute or make your code worse.
