Question

I’m using Devise and Can-Can for my community blog and currently looking for a way to re-direct ‘only’ the Admins and Moderators to the views/admin/index page directly once they sign in. Not sure if I can do this in the routes.rb or Sign In form? Any help appreciated…

application_controller

class ApplicationController < ActionController::Base
protect_from_forgery
rescue_from CanCan::AccessDenied do |exception|
flash[:alert] = exception.message
redirect_to root_url
end
end

routes.rb file

root :to => "articles#index"

sessions/new.html.erb

<h2>Sign In</h2>

<%= form_for(resource, :as => resource_name, :url => session_path(resource_name)) do |f| %>

<p><%= f.label :email %><br />
<%= f.text_field :email %></p>

<p><%= f.label :password %><br />
<%= f.password_field :password %></p>

<% if devise_mapping.rememberable? -%>
<p><%= f.check_box :remember_me %> <%= f.label :remember_me %></p>
<% end -%>

<p><%= f.submit "Sign In" %></p>
<% end %>

error

In your application_controller add something like this:

class ApplicationController < ActionController::Base

  def after_sign_in_path_for(resource)
    if current_user.role?("admin") or current_user.role?("moderator")
      admins_index_path    # Make sure this route exists in your app!
    else
      stored_location_for(:user)
    end
  end

end

Alternative (for Devise 1.1.x):

class ApplicationController < ActionController::Base

  def stored_location_for(resource)
    if current_user && (current_user.role?("admin") || current_user.role?("moderator"))
      return admin_index_path    # Make sure this route exists in your app!
    end
    super(resource) 
  end

end
