Displaying a column of associated names in ActiveAdmin

I have two models, Listing and Invitation, associated with has_and_belongs_to_many. I am looking at invitations through ActiveAdmin and would like to display the names of the associated listings. I attempt this with the following code:

ActiveAdmin.register Invitation do
  index do
    column("Listings") { |invitation| invitation.listings.each do |listing|
                          listing.name
                          end
                       }
    default_actions
  end
end

But nothing shows up. How can I get this to work?

I am assuming that you want a single column with all the listings names of the invitation. Please try the following

column 'listing' do |invitation|
  invitation.listings.collect(&:name).join(', ')
end

You might want to customize this later on and add a includes(:listings) to increase db retrieval performance.
