[Rails] Re: ActiveRecord::Base.transaction - SystemStackError - stack level too deep:

This is the TransactionAttributes

module TransactionAttributes

  def success

    success

  end

  def success=(success)

    self.success = success

  end

  def errors

  errors

  end

  def errors=(errors)

  self.errors = errors

  end

end

The reason for these was i was trying to set a property on a returned object or the errors. I yet to figure out a way i can return a more descriptive error message from the transaction back to the controller. 

I'll fix the style note. That just happens to populate when using a tab trigger in Sublime.

This is the table schema

# == Schema Information

#

# Table name: resources

#

#  id            :integer          not null, primary key

#  resource_name :string(255)

#  teacher_id    :integer

#  student_id    :integer

#  source_id     :string(255)

#  created_at    :datetime         not null

#  updated_at    :datetime         not null

#  resource_type :string(255)

#

The SystemStackError - stack level too deep:

  actionpack (3.2.13) lib/action_dispatch/middleware/reloader.rb:70:in `' 

is the only thing i get in the console.

This is whats returned in the response.

SystemStackError at /resources

Is there something else i can do to that would be helpful?

I have a StackOveflow with more detail - http://stackoverflow.com/q/16930511/1408461

As stated in the SO. If I try to save the record to the database outside the transaction it saves just fine. I only get the error in the transaction.
