ActiveAdmin - show attributes from association model

I have Registration model that has_many players {Player}. Registration has registerer's first name field and last name field, and a Player has such fields as name, date_of_birth, club. From users's perspective it is possible to add up to 3 players on the registration form so a Registration will always have up to 3 players.

Now, in Active Admin on Registration Index view I would like to show those 3 players' attributes, somehow like this.

Registration

First_name | Last name | Players           |
                         Name : ...     
                         Date of birth: ...
                         Club :...

                         Name: ...
                         Date of birth: ...
                         Club :...

Or maybe like this.

First_name | Last name | Player name | Player date of birth | ...  | Player name | Player date of birth |

Though I think the first way would be better.

So my Registration can have max 3 players associated with it and I would like to display players attributes on Registration index page.

Is this possible?

You could build a method that displays the player details with line separators

def show_players
  players.map do |player|
    "name: #{player.name}\ndob: #{player.date_of_birth}\nclub:#{player.club}\n"
  end.join("\n")
end

Then in your admin index block include the method

column :show_players
