Change ActiveModel Serializer based on controller

Question

How can I have a certain set of controllers use a different adapter?

I think I can do something like this in a before_filter :

ActiveModel::Serializer.config.adapter = :json

Then on another set of controller's before_filter :

ActiveModel::Serializer.config.adapter = :json_api

The code won't be threadsafe though..

Answer 1

Based on the code, you can specify the adapter in your controller action like that:

render json: @users, adapter: :json_api

It is of course not that convenient, as having a before_action in the base controller, but should be threadsafe.
