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/

I want to redirect admins/sign_in path when I just enter above url, login page is opening sometimes but after click on login button every time I get this error and not sign in. How to solve this problem?

error:

Filter chain halted as :require_no_authentication rendered or redirected

Answer 1

look like you're trying to log in the same user again without a sign out

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

You can achieve the same with this

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

A logged user can't sign in again...

You can try this, in your session_controller.rb add

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