Issues with Active Model Serializers
The ActiveModel::Serializer gives you a nice DSL to handle attributes and relationships when serializing objects.

No Matter What I do I only get a normal object hash https://github.com/rails-api/active_model_serializers/issues/706

for a belongs_to :category, I would do
