Usage

Decorate All fields

• Model

class Author < ActiveRecord::Base
  # first_name:string last_name:string
end

• Decorator

module AuthorDecorator
  def full_name
    "#{first_name} #{last_name}"
  end
end

• GraphQL Type

Types::AuthorType = GraphQL::ObjectType.define do
  name "Author"
  field :full_name, !types.String
end

then GraphQL::Field resolves full_name by decorated Author objects.

Decorate only specific fields

If you want to decorate only specific fields ActiveDecorater::GraphQL provides options to control decoration default and field decoration.

• Control decoration defaults (config/initializers/active_decorator-graphql.rb)

ActiveDecorator::GraphQL::Config.decorate = false # default: true

• Control specific field decoration (GraphQL Type)

Types::AuthorType = GraphQL::ObjectType.define do
  name "Author"
  field :full_name, !types.String, decorate: true
  # true:  force enabling decoration
  # false: force disabling decoration
end
