如何在Jekyll中将对象添加到site变量中？

module MyPlugin
  class MyGenerator < Jekyll::Generator
    def generate(site)
      # 创建一个新的对象
      my_object = {
        "name" => "My Object",
        "description" => "This is my custom object"
      }

      # 将对象添加到site变量中
      site.data["my_object"] = my_object
    end
  end
end

# 注册插件
Jekyll::Hooks.register :site, :pre_render do |site|
  MyPlugin::MyGenerator.new.generate(site)
end

<h1>{{ site.data.my_object.name }}</h1>
<p>{{ site.data.my_object.description }}</p>
