推荐答案

我已经在 Quora 上问过这个问题了..

I already ask this question on Quora..

对于真正有兴趣实施 Quora/Facebook URL 的人.这是 Rails3 中的一个技巧:

For who really interested to implement Quora/Facebook URLs like. Heres a tip in Rails3:

制作一个名为 slugs 的表格:

Make a table called slugs :

#  slug | model_id |  model
# ===========================
# simple data:
#  one  |    2222    |  post
#  two  |    1111    |  user
#  six   |    5432    |  comment

现在在 routes.rb 中将此行添加到底部:

Now in routes.rb add this line to the bottom:

match '/:id', :to => proc { |env|
  id = env["action_dispatch.request.path_parameters"][:id]
  model = Slug.find_by_slug(id).model
  controller = [model.pluralize.camelize,"Controller"].join.constantize
  controller.action("show").call(env)
}, :as => :slugable

所以，如果我们去路由中的/one，它会被翻译成:

so, if we go to /one in the routes, it translated to be:

id: one
so from the slugs table,
model: post
and the route will point to "posts#show"

现在在所有控制器的 show 操作中

Now in the show action in all controllers

@something = Model.find_by_slug(params[:id])
