Routing error when signing into ActiveAdmin

Question

I just installed ActiveAdmin and everything was going well:

The gem is installed and I ran the install command. I was able to go to localhost:3000/admin and signed in with the admin@example and 'password' credentials as laid out in the documentation.

However, when I click on "Login", I get the following:

No route matches {:action=>"show", :controller=>"users", :id=>nil}

My routes.rb file:

devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)

devise_for :users, :path => '', :path_names => {:sign_in => 'login', :sign_out => 'logout'}

resources :offers

resources :users do
collection do
  get :currentoffers
end

My users_controller.rb:

def index
end

def show
    @user = User.find(params[:id])
end

def currentoffers
    #calls the currentoffers.js.erb file
    respond_to do |format|
        format.html
        format.js
    end
end

What I get when I run rake routes:

admin_root            /admin(.:format)                          admin/dashboard#index

Would anyone know why I am getting this error? Is is that including the users resource in the routes.rb file is interfering with ActiveAdmin?

---Update:

# Application_controller.rb:

class ApplicationController < ActionController::Base
    protect_from_forgery

def after_sign_in_path_for(resource)
    user_path(@user)
end

end

did you click Log In on site or in admin section? where did it redirect to? — Yuri Golobokov

I clicked Log In in the admin section, localhost3000/admin. I didn't get redirected anywhere - I just was shown a blank page with the error above. — Zephyr4434

try this,

def after_sign_in_path_for(resource)
  user_path(resource)
end

problem is in,

 user_path(@user)

where @user is not defined, hence nil.

Strage - It works now, but when I log in with the admin credentials, instead of taking me to the admin dashboard, it takes me to /users/1 - must be a simple routing error, any idea on how to route correctly to the activeadmin side?

Not as that strange. It is because you are overriding the devise url path after. You can replace user_path(resource) by admin_dashboard_path in after_sign_in_path_for(resource) or whatever you want.

or you can check if it is admin user, by resource.instance_of?(AdminUser) and redirect conditionally.

move this line

ActiveAdmin.routes(self)

above this line

devise_for :admin_users, ActiveAdmin::Devise.config

moving

ActiveAdmin.routes(self)

before

 devise_for :admin_users, ActiveAdmin::Devise.config

causes an error because of ActiveAdmin bug of extra '/' route being generated, the bug was fixed in ActiveAdmin 0.6.1 upgrading ActiveAdmin will allow the fix that solved the problem for us.
