Dear monks,

modeling a DBIC classes hierarchy I went into a problem which must have been solved thousand times.

I have a base class, which instances are straightforwardly serialized into a table (object attribute is a table column) via DBIx::Class.

Then I have an extension class, with additional attributes also to be serialized into database.

I (intuitively) created a new table containing only the extending attributes and foreign key referencing the base table.

So for one logical object I have two physical rows in a database. Is there a way how to reasonably represent such subclass using DBIx::Class, i.e. to have DBIC instance working (insert, update, search) with two (more) records at once?

I would like to avoid a "pure database" solution based on updateable database view.

I can use "inline" view as the table. Of course they are not updatable.

    select *
    from (
        select ... from table1, table2
        where ...
    )
    where ...

I appreciate any clue and hope for simple answer like: "... well known problem with many good solutions, just see the discussion at ...".
