Shopify / Rails应用程序：在安装后我应该在哪里调用我想立即运行的方法？

Question

我使用shopify_app gem在Rails上构建了Shopify应用程序。我想在商店所有者安装应用程序后立即调用一个方法，但是我无法弄清楚我会在哪里调用它。

创建应用程序的新实例时，控制器＃操作是什么？

我有

class ApplicationController < ActionController::Base
  include ShopifyApp::Controller
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
end


class AuthenticatedController < ApplicationController
  before_action :login_again_if_different_shop
  around_filter :shopify_session
  layout ShopifyApp.configuration.embedded_app? ? 'embedded_app' : 'application'
end


class HomeController < AuthenticatedController
  def index
    @customers = ShopifyAPI::Customer.find(:all, :params => {:limit => 100})
  end
end


class SessionsController < ApplicationController
  include ShopifyApp::SessionsController
end
