如何將Rails devSign_in路徑設置為根URL

Question

devise_for :admins, path: 'admins' 

devise_scope :admin do
  root to: "devise/sessions#new"
end

http://localhost:3000/

我只想在url上方輸入時就想重定向admins / sign_in路徑，登錄頁面有時會打開，但是每次我遇到此錯誤而不登錄時都單擊登錄按鈕。如何解決此問題？

錯誤：

由於：require_no_authentication呈現或重定向，過濾鏈停止

Answer 1

看起來您正在嘗試再次登錄同一用戶而未注銷

devise_for :admins, path: 'admins' 

devise_scope :admin do
  authenticated :admin do
    root 'home#index', as: :authenticated_root
  end

  unauthenticated do
    root 'devise/sessions#new', as: :unauthenticated_root
  end
end

Answer 2

你可以做到這一點

routes.rb

root "home#index"
devise_for :admins, path: 'admins' 

home_controller.rb

class HomeController < ApplicationController
def index
   if not admin_signed_in?
     redirect_to admin_session_path
   end
end

Answer 3

已登錄的用戶無法再次登錄...

您可以嘗試此操作，在session_controller.rb中添加

class Users::SessionsController < Devise::SessionsController
  prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ]
end
