ruby-on-rails - 具有祖先的模型的 Rails 路线

Question

我有一个模型类别：

class Category < ActiveRecord::Base
  has_many :item_categories, :dependent => :destroy
  has_many :items, :through => :item_categories
  has_ancestry
end

和型号项目：

class Item < ActiveRecord::Base
  has_many :item_categories, :dependent => :destroy
  has_many :categories, :through => :item_categories, :uniq => true
end

我使用这个宝石 - https://github.com/stefankroes/ancestry

因此，网站上的 URL 可以是：

/category-slug/ - "categories#show"
/category-slug/subcategory-slug
/category-slug/subcategory-slug/subsubcategory-slug
/category-slug/item-slug - "items#show"
/category-slug/subcategory-slug/item-slug
/category-slug/subcategory-slug/subsubcategory-slug/item-slug

这个网址的路线看起来如何？这可能吗？

Answer 1

我建议你这样解决问题：

/category1/ - "categories#show"
/category1/category2
/category1/category2/category3
/category1/item - "items#show"
/category1/category2/item
/category1/category2/category3/item-slug

我会通过以下途径解决这个问题：

resources :categories do
  resources :categroies
  resources :items
end

这给出了：

category_categroie GET /categories/:category_id/categroies/:id(.:format) {:action=>"show", :controller=>"categroies"}
     category_item GET /categories/:category_id/items/:id(.:format)      {:action=>"show", :controller=>"items"}
          category GET /categories/:id(.:format)                         {:action=>"show", :controller=>"categories"}

这解决了以下六个问题：

/categories/1
/categories/1/categories/2
/categories/2/categories/3
/categories/1/item/4
/categories/2/item/5
/categories/3/item/6

也许你可以让你的程序使用这个解决方案。
