ruby-on-rails - 具有多个类别的 Rails 嵌套路由

Question

我试图弄清楚如何获得这样的嵌套路由：

match '/:category_id/:subcategory_id/:id', via: 'get', controller: 'categories', action: 'index', as: 'category'

子类别和 id 不应该是必需的。应该可以得到：

• 类别索引
• 子类索引
• 身份证显示

类别和子类别应使用相同的控制器操作。类别和子类别当然使用相同的祖先/树模型。

我对这个有点迷失了。任何提示都会很棒！

Answer 1

It sounds like nested resources would get you most of what you want:

resources :category do 
  resources :subcategory 
end 

Have you considered/tried this?
