Add custom items at header menu in ActiveAdmin

I want to add a link like link_to ("Edit yout profile", edit_user (current_user)) at header in ActiveAdmin. Is that possible ?!

Solution 1:

Recent versions of ActiveAdmin allow you to do this in your active_admin.rb initializer:

config.namespace :admin do |admin|
  admin.build_menu do |menu|
    menu.add :label => 'Custom Menu' do |submenu|
      submenu.add :label => 'Custom Link', :url => custom_path
    end
  end
end

Solution 2:

For recent versions of active admin, there are two solutions, both kind of unfortunate.

Any of your Resources with menu false can be set to menu label: "Google", url: "http://www.google.com". This is unfortunate because it is highlighted as selected if you are on the resource from which you set it.

The other solution is to over-write the ActiveAdmin::Views::Header as above, but updated.

module ActiveAdmin
  module Views
    class Header < Component

      def build_global_navigation
        item = ActiveAdmin::MenuItem.new(label: "google", url: "http://www.google.com")
        @menu.add item
        insert_tag view_factory.global_navigation, @menu, :class => 'header-item'
      end
    end
  end
end

This doesn't work exactly right, as you can't set things like parent: "Developer" for the menu item... Anyway, I may make a fork so you can add items in the initializer to a particular namespace...Did anyone open an issue for this? I didn't see one.

Update: I think this is the cleanest way to implement this (without contributing to active admin).

ActiveAdmin.register_page "Queue" do
  menu parent: "Developer", url: '/admin/resque'
end

Solution 3:

If you're using a later version of ActiveAdmin that has the capability for custom pages, you can do the following:

 ActiveAdmin.register_page "Store Admin" do
   controller do
     define_method(:index) do
       redirect_to "/store/admin"
     end
   end
 end

This overrides the index action of the PageController which normally just renders the page, but you can instead have it redirect to wherever you want to go, such as edit_user_path
