Example of changing the utility navigation in the layout (Top right of nav bar)

active_admin.rb

# This assumes you are using that you are using Active Admin from master.
# You can do this with 0.4.2 but you would need to override the HeaderRenderer instead

# config/initializers/active_admin.rb
ActiveAdmin.setup do |config|

  # View a list of all the elements you can override
  # https://github.com/gregbell/active_admin/blob/master/lib/active_admin/view_factory.rb
  config.view_factory.utility_navigation = MyCustomUtilityNav

end

# The subclass the utility nav
class MyCustomUtilityNav < ActiveAdmin::Views::UtilityNav
  
  # Override the build method which accepts the current ActiveAdmin::Namespace
  def build(namespace)
    span("Hello From My Utility Nav")
    super(namespace)
  end

end

# OR Create a whole new utility nav

class MyCustomUtilityNav < ActiveAdmin::Component

  def build(namespace)
    span("Hello From My Utility Nav")
  end

  def tag_name
    'p'
  end

end

Been trying to get this working. As soon as I have a class that inherits from ActiveAdmin::Views::UtilityNav or ActiveAdmin::Component, I am getting this error:

Showing [...]/activeadmin-0.5.0/app/views/active_admin/resource/index.html.arb where line #1 raised:

undefined method `dashboard_path' for         <ul class="header-item" id="tabs"></ul>
:ActiveAdmin::Views::TabbedNavigation

Any ideas? Do you expect this kind of thing to work still? I'm using 0.5.0. I've looked around the codebase and haven't found out what is wrong.

Thanks so much.

Never mind, this works as expected. I was experiencing the problem because I had tried to scope ActiveAdmin within routes.rb, which messed up the paths.

I had tried this:

scope '/admin', as: :admin do
  ActiveAdmin.routes(self)
end

And was registering some resources with namespace: false so I could have other namespaces nested within /admin/. I still don't have a good solution for doing that, but I'm just using other routes for now.
