ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: 'Transactions::DummyDdnlTransaction'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. P

FIXED: Transaction is a reserved word, and it cannot be used even though I put it into its own module. So my guess is Transactions::Transaction still somehow got resolved to the Rails internal Transaction class.

Renamed the Transaction (and its subclasses) to Transact and it works fine now.
