def attributes_for_gl_transaction
    identifier = has_attribute?(:visible_id) ? visible_id : id
    {
        source: self,
        location: try(:location) || Location.default,
        description: "#{self.class.to_s.demodulize} #{identifier}"
    }
end

#save ⇒ Object

N.B. We are overriding ActiveRecord::Base#save This is so we can wrap the save call inside a GlTransaction.record block which will collect any GlPostings and then collapse them down at the end of the block in order to prevent multiple postings to the same account.
