thoughtbot/paperclip — Issue #744: Using paperclip with STI model in Rails 3.2 doesn't work

State: open

I have the following parent class:

class Asset < ActiveRecord::Base
belongs_to :assetable, :polymorphic => true
end

And sub class:
class User::Avatar < Asset
has_attached_file :attachment, :styles => { :medium => "300x300>", :thumb => "100x100>" }
end

I get this error:
undefined method `read_inheritable_attribute'

I found that `read_inheritable_attribute' has been deprecated in rails 3.2. This need to be fixed in paperclip?
