Rails的：我如何航线无关联的资源？ [英] Rails: How do I route unassociated resources?

问题描述

我有四个型号：

class User < ActiveRecord::Base
  has_many :posts
end

class Category < ActiveRecord::Base
  has_many :posts
end

class Post < ActiveRecord::Base
  belongs_to :user
  belongs_to :metric
  has_many :comments
end

class Comments < ActiveRecord::Base
  belongs_to :post
end

我希望能够在一定类别的访问后为特定用户。例如：

I'd like to be able to access a post within a certain category for a specific user. For example:

http://domain.com/users/1/categories/1/posts

此外，我希望看到所有类别的清单，如果我访问：

Also I want to see a list of all categories if I visit:

http://domain.com/users/1/categories/

和由于这些类别是固定同样为所有用户，用户和类别没有直接关联。正因为如此，我不太确定如何配置的routes.rb文件类别内访问职位的用户。我倒是AP preciate任何建议。谢谢！

Since categories are fixed and the same for all users, User and Category don't have a direct association. Because of this, I'm not quite sure how to configure the routes.rb file to access posts within a category for a user. I'd appreciate any suggestions. Thanks!

推荐答案

您可以使用嵌套的资源，要做到这一点，如：

You could use nested resources to do that like :

resources :users do
  resources :categories
end
