Question

这是我的link_to

<%= link_to sub_category.name, controller: :posts, action: :product, id: "#{sub_category.slug}-#{sub_category.id}" %>

指向网址

http://localhost:3000/posts/product/fifith-category-s-sub-category-2

我需要如下网址

http://localhost:3000/fifith-category-s-sub-category-2

我该怎么做。

我的route.rb

resources :posts
match ':controller(/:action(/:id))(.:format)', via: [:get,:post]

Answer 1

如果您希望路径/:id与您的posts#product匹配，那么您的路线中应该有类似的内容：

resources :posts
match ':id', to: 'posts#product`, via: :get
match ':controller(/:action(/:id))(.:format)', via: [:get, :post]

Answer 2

@MarekLipka建议的是正确的，但是定义这样的路线会占用你应用中的所有单级命名空间，即“/ anything”默认路由到posts#product。

我建议使用某种形式的标识符来确定哪些路由应该转到posts#product。什么对你有用取决于你想要这样做的原因。几个选项是：

使用短命名空间：

scope '/pp' do 
    get ':id', to: 'posts#product
end
# "/pp/:id" routes to 'posts/product'
# pp is a random short name I picked, it could be anything

# link
<%= link_to sub_category.name, "pp/#{sub_category.slug}-#{sub_category.id}" %>

使用约束：

get ':id', to: 'posts#product`, constraints: { :id => /sub\-category/ }
# only id's with 'sub-cateogry' route to 'posts/product'

# link (assuming that sub_category.slug has 'sub-category' words in it)
<%= link_to sub_category.name, "#{sub_category.slug}-#{sub_category.id}" %>
