Redirect Active Admin login to Devise Login

Question

In my App I have successfully installed Devise and it works perfectly nice. Then I have first time installed Active Admin for Admin panel and have set path. Now when I try to login in Active Admin localhost:3000/admin/login it redirect me to Devise's login page. I know there may be silly mistake but not aware how to solve this issue??

app/config/initializers/active_admin.rb

ActiveAdmin.setup do |config|  #I have removed comments
 config.site_title = "Shopaholic"
 config.authentication_method = :authenticate_admin_user!
 config.current_user_method = :current_admin_user
 config.logout_link_path = :destroy_admin_user_session_path
 config.batch_actions = true
end

app/config/initializers/devise.rb

Devise.setup do |config|
  config.secret_key = '28c01a5ccf820bb594d2b6421becfa6487df79dad52a57d49cf61f802ea00c7364215f43cdf87463503e658da69e182f8c35d668577f975fea2bdee736a5d20a'
  config.mailer_sender = '[email protected]'
  require 'devise/orm/active_record'
  config.authentication_keys = [ :email ]
  config.case_insensitive_keys = [ :email ]
  config.strip_whitespace_keys = [ :email ]
  config.skip_session_storage = [:http_auth]
  config.stretches = Rails.env.test? ? 1 : 10
  config.remember_for = 2.weeks
  config.password_length = 8..128
  config.reset_password_within = 6.hours
  config.default_scope = :users
  config.sign_out_via = :delete
end

routes.rb

Shopaholic::Application.routes.draw do
  root :to => "products#products_list"
  #root to: "admin/dashboard#index"
  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)

  devise_for :users
  ActiveAdmin.routes(self)
end

If you required any further information then let me know I will Update. Please help me to solve this issue.. Thanks in advance

Answer 1

in your

config/initializers/active_admin.rb

add the following to the bottom of the setup block

ActiveAdmin::BaseController.class_eval do
  skip_before_filter :authenticate_user!
end

UPDATE: with Rails 5.0 and higher you'll want to add it like this:

config.skip_before_action :authenticate_user!

Answer 2

I think If you have this block in application_controller.rb then it will redirect you to Devise's login page:

def after_sign_in_path_for(resource)
    users_path
end

To resolve this redirection use this block instead of above block:

def after_sign_in_path_for(resource)
    if resource.is_a?(AdminUser)
        admin_dashboard_path
    else
        users_path
    end
end

And if you have still issue due to "before_action :authenticate_user!" this on application_controller.rb then as per @YodaTravis use this block in bottom of config/initializers/active_admin.rb

ActiveAdmin::BaseController.class_eval do
    skip_before_filter :authenticate_user!
end

It will work for you!!
