Ruby on rails 如何使用Rails 5.2构建url以从表单创建子项？

我的应用程序管理BusinessProcess实例和子部署对象实例。正在从当前BusinessProcess Show视图创建新的DeployedObject实例：

<%= link_to 'New object', new_business_process_deployed_object_path(@business_process, parent_id: @business_process.id, parent_class: @business_process.class.name) %>

我尝试了几种基于api.rubyonrails.org文档或文章的url语法，但仍然无法编写url来处理此表单的结果

我还尝试直接基于派生\部署\对象\路径构建请求，但没有取得更多成功

你能帮我建立这个url吗？非常感谢

以下是路由.rb配置摘录：

  resources :business_processes do
    resources :business_rules, :only=>[:new, :create]
    resources :deployed_objects, :only=>[:new, :create, :derive] do
      member do
        post :derive
      end
    end
    resources :activities, :only=>[:new, :create]
    member do
      post :activate
    end
    collection do
      get :index_all
    end
  end

  resources :deployed_objects do
    resources :deployed_skills                   # Properties of a business object
    resources :scopes
    member do
      post :new_version
      post :make_current
      post :finalise
      post :activate
      post :derive
      post :open_cart     # Declares that the current business object collects skills as a cart
      post :close_cart    # Unsets the current business as cart
    end
    collection do
      get :index_all
    end
  end
