Heroku构建一个附加组件（未定义的局部变量或方法

Question

heroku_controller.rb

class HerokuController < ApplicationController

    def resources
    service = Service.create!(
      plan: json_params[:plan],
      region: json_params[:region],
      heroku_uuid: json_params[:uuid] # Will be present in all future requests
    )

    response = {
      id: service.id, # Unique identifier from your system
      config: { "SERVICE_URL" => service.url },
      message: "Welcome to our service"
    }

    status 200
    response.to_json

    end
  end


 response = {
   id: service.id, # Unique identifier from your system
   config: { "SERVICE_URL" => service.url },
   message: "Welcome to our service"
 }

 status 200
 response.to_json

 end
end

我不明白如何创建这个是Service.create！ 我应该创建新模型，或者什么？
