Add transaction ID to audit records

audited-transaction_id.rb

# Using XID gem https://github.com/adzap/xid
# with Audited gem https://github.com/collectiveidea/audited/commits/master

# This adds the transaction ID to the audit record so you can group all changes together which happened in the same transaction, # which is hopefully the same use action. This obviously needs you add a transaction_id column to the audits table.

Audited::Adapters::ActiveRecord::Audit.class_eval do
  before_create :set_transaction_id

  def set_transaction_id
    self.transaction_id = ActiveRecord::Base.connection.transaction_id
    nil
  end
end
