Rails customizing the administrate gem

Question

I have location, concert and artist model as

class Location < ApplicationRecord
  has_many :concerts, dependent: :destroy
  has_many :artists, through: :concerts
end

class Concert < ApplicationRecord
  belongs_to :location
  belongs_to :artist
end

class Location < ApplicationRecord
  has_many :concerts, dependent: :destroy
  has_many :artists, through: :concerts
end

I'am currently using the rails administrate, now I want to customise the rails administrate gem where instead of displaying the id while adding the new concert I want to get the location and artist name there instead of there id's. I have attached the screenshot there.

In your Location and Artist dashboards, you need to define a display_resource method:

class LocationDashboard < Administrate::BaseDashboard
  def display_resource(location)
    location.name # or whatever attribute you want to use
  end

  # ...
end

Do the same in your Artist Dashboard and you should be good to go :)
