ActiveAdmin: Modifying Index Table Based on Active Scope

Question

Suppose I have an ActiveAdmin model with two scopes like so:

ActiveAdmin.register Book do

  scope :all, default: true
  scope :smith #all books by author 'smith'

  index do
    column :title
    column :published_year
    column :author
  end
end

I don't want/need the 'author' column when the user has selected the 'smith' scope.

So is there a way to get access to the current scope and only show the author column in one of the scopes? I suppose for this example I could use a custom view and check the actual content of the data but I am hoping there is an easier and better way.

Answer 1

you can try something like that

index do
    column :title
    column :published_year
    column :author unless params['scope'] == 'smith'
  end

Answer 2

You also have access to the @current_scope object, and you can do @current_scope.scope_method to get the underlying scope method
