Rails 4 + Devise：无效的路线名称，已在使用中

Question

我正在按照此操作方法在成功注册后修改确认页面。

https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-up-(registration)

我按照它说的做所有事情，但我得到了这个错误：

in `add_route': Invalid route name, already in use: 'new_user_session'  (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

我猜 wiki 没有更新为使用带有 Rails 4 的 Devise，但我没有找到足够的信息来修复错误。

返回错误的行是下一个（routes.rb）：

devise_for :users, :controllers => { :registrations => "registrations" }

有什么建议吗？

谢谢。

编辑 --

registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController

    protected

    def after_inactive_sign_up_path_for(resource)
        '/sign_up/inactive'
    end
end

routes.rb

root :to => 'home#index'
devise_for :users
resources :users

devise_for :users, :controllers => { :registrations => "registrations" }

Answer 1

您的 routes.rb 中有两条路线 devise_for :users - 删除第一条。
