  Can you open a ticket with reportable gem if you are still having an issue. It does not seem like it is a rails issue.

  The reportable gem includes Saulabs::Reportable into ActiveRecord::Base which makes Saulabs::Reportable::Report available inside Account. AR::Base#compute_type first looks inside the class to see if the constant is available so you need tell it to reference the top level constant by prefixing it with '::', e.g:

  class Account < ActiveRecord::Base
    has_many :reports, :class_name => '::Report'
  end

  Ok, I tried to fix it with

  :class_name => ::Report.name
  

  but that wouldn't fix it of course. Guess ::Report.name is 'Report' not '::Report'

  The :class_name option should be passed a string '::Report' - by doing as ::Report.name it removes the leading scope operator.

  Yes, that's what I meant to say.

  Which version of rails are you using?

  This definition for the Account model works for me in 2.3.8:

    class Account < ActiveRecord::Base
      has_many :reports, :class_name => '::Report'
    end
  
    >> Account.first.reports
    => [#<Report id: 1, account_id: 1, created_at: "2010-06-28 08:53:34", updated_at: "2010-06-28 08:53:34">]

  Yep, the version with '::Report' works, the one with ::Report.name does not since that will result in 'Report' which will then result in Reportable's Report class being found since Saulabs::Reportable is included in ActiveRecord::Base.

  I don't think this is specific to any Rails version. I tried it with 2.3.5.

  However, this is not a Rails/ActiveRecord problem - the ticket really is invalid as noted above.
