tony, i notice that defining a relationship with might_have doesn't add a column to $class->__hasa_columns. is that something you're likely to change? it's enormously useful for me to be able to define relationship columns which might not be occupied - eg person foo might_have a mugshot in the images table - but at the moment i don't think i can use it because my input functions depend on reading $class->columns and attempting to fill the vacancies that defines.
(i use a mechanism quite similar to your Class::DBI::CGI, but older and crapper. i'm hanging on to it because it's iterative and allows several linked objects to be created at once based on prefixes in fieldnames) thanks for the new version, btw. will On Monday, June 24, 2002, at 07:11 AM, Tony Bowden wrote: > > Class::DBI is a simple database->object mapping system.
