ArgumentError - Unknown key: :order in Rails 4.1

[jduarte]

I'm using the following stack:

• Rails 4.1
• Ruby 2.0.0-p451
• Mac OS X 10.9.2

With the given model

class Tag < ActiveRecord::Base
  acts_as_nested_set

  belongs_to :account

  has_many :expense_tags
  has_many :expenses, through: :expense_tags
end

The following error occurs:

[jduarte]

Due to later versions of rails you can't use activerecord methods outside a scope block in associations.

Fixed on 0429d6a82be40081caf40b976fed6a4d6ab294e3

No release of this fix yet?

[parndt]

I believe it's been in versions 3.0.0.rc3 through 3.0.0.rc6?
