Changing Active Model Serializers Default Adapter

Question

If I want to switch from the default attributes adapter to the JSON API adapter, where would I do this?

The getting started states this:

Generally speaking, you as a user of AMS will write (or generate) these serializer classes. If you want to use a different adapter, such as a JSON API, you can change this in an initializer:

ActiveModel::Serializer.config.adapter = :json_api

What initializer are they referring to? Do I create a new one? Sorry for the noob question

Answer 1

In general, initializers are put under the app/config/initializers directory in a Rails app.

So, in your case, you can create a new file there: ams.rb and put those content in that file:

# app/config/initializers/ams.rb    
ActiveModel::Serializer.config.adapter = :json_api

Also, see this github issue.

If you want to be using the :json_api format, you have to use the 0.10.0 branch off of Github.

Answer 2

For newer version of AMS put this to config/initializers/ams.rb:

require 'active_model_serializers'

ActiveModelSerializers.config.adapter = :json_api
