如何将Rails devSign_in路径设置为根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上方输入时就想重定向admins / sign_in路径，登录页面有时会打开，但是每次我遇到此错误而不登录时都单击登录按钮。如何解决此问题？

错误：

由于：require_no_authentication呈现或重定向，过滤链停止

Answer 1

看起来您正在尝试再次登录同一用户而未注销

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

你可以做到这一点

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

已登录的用户无法再次登录...

您可以尝试此操作，在session_controller.rb中添加

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