Rails 3 路由范围和/或嵌套

我无法确定我不想嵌套的路线。

我有以下路线:

  resources :foos
  resources :bars
  resources :bazs do
    resources :hellos
    resources :worlds
  end

foo、bar 和 baz 模型都属于用户模型。我不想嵌套另一个层,但我确实想在我的 url 中添加一个与用户的永久链接属性相对应的前缀(类似于每个以用户名为前缀的 github 存储库)。因此,我在所有控制器上都有一个 before 过滤器

  def get_scope
    @user = User.find_by_permalink(params[:permalink])
  end

修改了 to_param 感谢 @cowboycoded

  class User < ActiveRecord::Base  
    def to_param
      permalink
    end
  end

我将这些路由包裹起来

  scope ":permalink", :as => :user do
    #nested routes here
  end

现在只要我将 @user 传递给每个非索引路由,一切都会正常工作。当它已经确定了作用域时,必须返回到我的所有视图并将 (@foo) 替换为 (@user, @foo) 似乎并不很干燥。

除非我弄错了,否则 to_param 方法只是替换 :id ,以便 /users/:id 等 url 显示为 users/permalink 而不是 users/1。我尝试在我的范围内使用这个 :id ,但它与 foo 的 :id 参数冲突并破坏了一切。也许与我缺少的路径有联系?

感谢您提出的任何建议!

I am having trouble scoping routes that I don't want to nest.

I have the following routes:

  resources :foos
  resources :bars
  resources :bazs do
    resources :hellos
    resources :worlds
  end

The foo, bar, and baz models all belong_to a user model. I don't want to nest another layer, but I do want to have a prefix in my url that corresponds to a user's permalink attribute (similar to each github repo prefixed by a username). So I have a before filter on all of my controllers

  def get_scope
    @user = User.find_by_permalink(params[:permalink])
  end

Modified to_param thanks to @cowboycoded

  class User < ActiveRecord::Base  
    def to_param
      permalink
    end
  end

I wrapped those routes with

  scope ":permalink", :as => :user do
    #nested routes here
  end

Now everything works fine as long as I pass @user to every non-index route. It doesn't seem very dry to have to go back to all of my views and replace (@foo) with (@user, @foo) when it is already scoped.

Unless I am mistaken, the to_param method simply replaces :id so that urls such as /users/:id appear as users/permalink instead of users/1. I attempted to use this :id in my scope, but it conflicts with foo's :id param and breaks everything. Maybe there is a connection to paths that I am missing?

Thanks for any suggestions that you may have!

您是否尝试过在模型中使用 to_param 方法?这将允许您覆盖默认值并使用 id 以外的其他内容,并将与 URL 帮助程序一起使用

http://api.rubyonrails.org/classes/ActiveRecord/Base.html#method-i-to_param

文档中的示例:

class User < ActiveRecord::Base
  def to_param  # overridden
    name
  end
end

user = User.find_by_name('Phusion')
user_path(user)  # => "/users/Phusion"

我不确定这在范围内的效果如何,因为我还没有尝试过,但我想值得一试。

Have you tried using the to_param method in your model? This will allow you to override the default and use something other than id, and will work with the URL helpers

http://api.rubyonrails.org/classes/ActiveRecord/Base.html#method-i-to_param

Example from documentation:

class User < ActiveRecord::Base
  def to_param  # overridden
    name
  end
end

user = User.find_by_name('Phusion')
user_path(user)  # => "/users/Phusion"

I'm not sure how well this plays with scope, since I haven't tried it, but I guess its worth a shot.
