model

Hi,

Should every model have an associated table in database? I have a model as a subclass of another model class. I am getting 'MySQL gone away' error while creating a new object of this subclass.

Any clues?

not necessarily. For example when using single table inheritance then a model and its subclasses will share a table, and you can of course have non-activerecord model classes that don;t use the database at all.

Refactor the common code between your tabled and table-less *models into a module, and let both models include that module.

*yes, it's still a model, even if it has no DB persistence.
