如何为 Rails 应用程序创建应用程序范围的 slug 路由? [英] How to create app-wide slug routing for Rails app?

问题描述

我正在开发的 Rails 应用中有许多不同的模型.我已经看到许多站点使用应用程序范围的 slug 路由方法.这是什么意思?

I have a number of different models in the Rails app I'm working on. I've seen a number of sites use an app-wide slug routing approach. What do I mean by this?

http://example.com/nick-oneill <-- This points to a User object
http://example.com/facebook    <-- This points to a Company object
http://example.com/developers  <-- This points to the users#index page

我知道 to_param 并在应用程序中创建对读者友好的 slug，但是我不知道有一种方法可以为各种对象设置根级 slug.您可以认为这与 Facebook 的 Graph API 类似:有不同的对象类型，但它们都存在于 https://graph.facebook.com/object-id

I'm aware of to_param and creating reader-friendly slugs within apps, however I'm not aware of an approach to have root-level slugs for a variety of objects. You can think of this being similar to Facebook's Graph API: there are different object types, but all of them exist at https://graph.facebook.com/object-id

任何见解将不胜感激！

推荐答案

使用 freindly_id 可能有办法做到这一点，但我认为友好 id 的问题是事物的范围受模型的限制.

There may be a way to do this with freindly_id but i think the problem with friendly id is things are scoped by model.

如果我想要真正的站点范围的 slugging，我会创建一个与我的所有模型都具有多态关系的 slugs 表.

If I wanted truely sitewide slugging I would create a slugs table with a polymorphic relationship to all my models.

Sluggable_type 和 sluggable_id，然后是带有完整永久链接/slug 的 slug 字段.

Sluggable_type and sluggable_id and then a slug field with the complete permalink/slug.

+---------------------------------------------+
| sluggable_type | sluggable_id |     slug    |
|      user      |       13     |  users/john |
+---------------------------------------------+

现在我可以做一个通配符捕获所有路由或在运行时为我的所有 slug 创建路由，并在更新受此 slugable 控制的模型时强制刷新路由.

Now i could do do a wildcard catch all route or create the routes for all my slugs at runtime and force a route refresh when a model is updated that was under this sluggable control.

routes.rb

  get "/*segments",
               :controller => 'slugs',
               :action => 'dynamicroute'

现在在你的 SlugsController 中实现一个类似的方法

Now in your SlugsController implement a method like

def dynamicroute
  segments = params[:segments]
  slugs.find_by_slug(segments)
  slug.sluggable_type.constantize.find(slug.sluggable_id) #retrive real record
  #some magic to handle the slugged item maybe redirect to the appropriate
  #controller or somehow call the show view for that controller
end

或

routes.rb

begin  
  Slug.all.each do |s|
    begin
      get "#{s.slug}" => "#{s.sluggable_type.demodulize.pluralize.camelize}#show"
    rescue
    end
  end
rescue
end

如果您使用第二种方法进行路由，请确保您调用

If you use the 2nd approach to routing make sure you call

YOUR_APP_NAME::Application.reload_routes!

编辑任何 slugged 记录后刷新路由表.

After editing any slugged record to refresh the routing table.

我们遇到了类似的问题，我们可能会尝试完善这种方法.

We've had similar issues and we may try our hand at gemifying this approach.
