Re: [Poop-group] ANNOUNCE: Class::DBI 0.89

[william r. <wi...@sp...>]

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
