关于ruby on rails：Active Model Serializer格式化JSON显示

Active Model Serializer formatting JSON display

我正在我的Rails应用程序中使用活动模型序列化程序，我想重构显示：

每当我访问http://localhost:3000/api/users/1时，我都会看到：

{"data":{"id":"1","type":"users","attributes":{"username":"Iggy1"},"relationships":{"items":{"data":[{"id":"1","type":"items"},{"id":"7","type":"items"}]},"lists":{"data":[{"id":"1","type":"lists"},{"id":"8","type":"lists"},{"id":"14","type":"lists"},{"id":"15","type":"lists"},{"id":"17","type":"lists"}]}}}}

我怎样才能让它看起来像：

}
}

我花了很多时间浏览适配器、渲染和体系结构，但找不到指南。首先，是否可以使它看起来像上面的第二个代码块？第二，如果可能的话，我该怎么做才能改变显示器？

def show
@user = User.find_by(id: params[:id])
@no_user_found = User.all #other alternative when user ID not found?
if @user.nil?
flash[:notice] ="No user found"
render json: @no_user_found, each_serializer: UserSerializer
else
render json: @user, each_serializer: UserSerializer
end
end

Rails.application.routes.draw do
ActiveModelSerializers.config.adapter = :json_api
namespace :api, defaults: { format: :json } do

resources :users do
resources :lists
end

resources :lists, only: [] do
resources :items, only: [:create, :index, :show, :update]
end

resources :items, only: [:destroy]
end
end
