动态 CMS 类似于 ruby​​ on rails 中的路由 [英] Dynamic CMS like routes in ruby on rails

问题描述

我想创建一个类似 CMS 的网站，用户从一些通用页面开始，即

I want to create a CMS like site where the user starts off with a some generic pages, i.e.

• 主页
• 关于
• 联系方式
• 等

从那里可以动态添加子页面，例如

and from there can add child pages dynamically, for example

• 主页
  • 文章
    • 文章1
      • 某事
        • 别的东西

        为了实现这一点，我计划使用某种自我引用关联，例如

        To achieve this I'm planning on using some kind of self-referential association like

        class Page < ActiveRecord::Base
          belongs_to :parent, :class_name => 'Page'
          has_many :children, :class_name => 'Page'
        end
        

        我正在努力解决的一件事是路线生成.因为可以动态添加页面，所以我需要为这些页面动态生成路由，并且无法知道页面可以嵌套多少层

        The one thing I'm struggling with is the route generation. Because pages can be added on the fly I need to dynamically generate routes for these pages and there is no way of knowing how many levels deep a page may be nested

        所以如果我从主页开始:/

        So if I start off with the homepage: /

        然后开始添加页面，即

        /articles/article1/something/something-else/another-thing

        /articles/article1/something/something-else/another-thing

        如何使用 rails 路由模型实现类似的功能?

        How can something like that be achieved with the rails routing model?

        推荐答案

        一旦你有办法为你的 Page 记录生成 URL 字符串(我会把这部分留给你)，你可以只映射 config/routes.rb 中的每个页面:

        Once you have some way to generate the URL string for your Page records (and I'll leave that part up to you), you can just map every page in config/routes.rb:

        Page.all.each do |page|
          map.connect page.url, :controller => 'pages', :action => 'show', :id => page
        end
        

        并让观察者钩住页面模型以在发生变化时重新加载路由:

        And have an observer hook the page model to reload routes when something changes:

        class PageObserver < ActiveRecord::Observer
          def reload_routes(page)
            ActionController::Routing::Routes.reload!
          end
          alias_method :after_save,    :reload_routes
          alias_method :after_destroy, :reload_routes
        end
        

        不要忘记编辑 config/environment.rb 以加载观察者:

        Don't forget to edit config/environment.rb to load the observer:

        # Activate observers that should always be running
        config.active_record.observers = :page_observer
