error undefined method `group_values' in active_admin rails

Question

I try to implements active_admin in my app, and i'm follow this tutorial :

http://activeadmin.info/documentation.html

But when i'm execute this command in my console :

rails generate active_admin:resource product

The file successfully generate :

app/admin/product.rb

But when i'm access index product page in active_admin i get error like this :

ActionView::Template::Error (undefined method `group_values' for #<Array:0xcfe093c>)

how to fix this? thanks before

Answer 1

In your admin/product.rb you can put this code:

ActiveAdmin.register Product, :as => "All Product" do

end

Hopefully, this will help.
