Question

我偶然发现了这个问题，我正在尝试路由我的登录路径，并且我正在尝试将GET /login发送到sessions#new并POST /login发送给{ {1}}。虽然，Rails似乎并不认为这不是一个

sessions#create

这会在启动时引发以下错误：

get "/login" => "sessions#new", :as => :login post "/login" => "sessions#create", :as => :login

最佳做法是做lib/action_dispatch/routing/route_set.rb:507:in 'add_route': Invalid route name, already in use: 'login' (ArgumentError) You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here: http://guides.rubyonrails.org/routing.html#restricting-the-routes-created，尽管我会得到resources :sessions, only: [:new, :create], as: :login和login_index_path之类的网址助手而不仅仅是new_login_path最初的意图吗？

Answer 1

这就是我在Rails应用程序上所做的。

get    'login'   => 'sessions#new'
post   'login'   => 'sessions#create'

我认为:as => :login部分是导致错误的部分，我认为这是指定别名，并且您不能为两条不同的路由使用相同的别名。

您可以将一个块传递给scope：

scope as: 'login' do
  get "/login" => "sessions#new"
  post "/login" => "sessions#create"
end

这也适用于更复杂的路线，例如：

scope as: 'post' do
  patch  '/posts/:id' => 'posts#update'
  put    '/posts/:id' => 'posts#update'
  delete '/posts/:id' => 'posts#destroy'
end

结果为：

$ rails routes -c post
Prefix Verb   URI Pattern            Controller#Action
post PATCH    /posts/:id(.:format)   posts#update
     PUT      /posts/:id(.:format)   posts#update
     DELETE   /posts/:id(.:format)   posts#destroy

使用相同：对于两个rails路由，使用GET和POST进行不同的操作
