Question

I’m trying to create a custom class for ActiveAdmin to try and clean up code out of the controller override in my Resource file.

I have a class creditcard.rb in /lib:

class Creditcard

def initialize
    1
end

end

And I have this controller code in subscriptions.rb

ActiveAdmin.register Subscription do

  controller do
    def update
    @test=Creditcard.new

Boom. uninitialized constant Creditcard. Anyone know how to use custom classes with ActiveAdmin?

Thanks!

You might have to add the lib directory to your autoload path if you’re using Rails 3+.

You can do this by adding this line to your application.rb file inside of your class Application < Rails::Application definition:

config.autoload_paths += %W(#{Rails.root}/lib)
