I stumble upon this error when loading a subclass of the Transaction
class. For full details, see the pastie:
Error message: 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. Please rename this column if you didn't intend it to be
used for storing the inheritance class or overwrite
Transactions::DummyDdnlTransaction.inheritance_column to use another
column for that information.
Have Googled around, tried solutions like self.subclasses and
require_dependency but they didn't work for me.
I'm on Rails 2.3.14.
