This attribute is an object, all inserted configuration this object it will be passed on to Active Model Serializers, eg.

set :active_model_serializers, { root: false }

By default, path is app/serializers. If you need a different path you can set your path, eg.

set :serializers_path, './whatever_path/serializers'

or you can disable auto require

set :serializers_path, false

Response JSON

When you return a json, you can send a the second parameter. This the second parameter is an object. This object may contain new configurations to assign to the Active Model Serializers or to rewrite any already set by default, eg.

root

get '/' do
  json Resource.first, { root: false }
end

scope

get '/' do
  json Resource.first, { scope: self }
end

Specify a serializer

If you wish to use an another serializer than the default, you can explicitly pass it through the renderer

1. For a resource:

json Resource.first, { serializer: ResourcePreviewSerializer }

2. For an array resource:

Use the default ArraySerializer, which will use each_serializer to serialize each element.

json @resources, { each_serializer: ResourcePreviewSerializer }
