I naively defined a model with numerous Compound PKs, only to
discover that I loose a lot of cool automagic development by doing so.
My question is this: How do you guys - WO Novices to Experts (Me
being a total Newbie) deal with Compound PKs? Do you avoid them
like the plague? Is it considered just part of bargain and no big
deal (i.e. Setting a delegate to create PKs)? Is it something I
will inevitably *have* to deal with and might as well get started?
Generally avoid them. However, when you need them you can usually
use the Propagate Primary Key feature to avoid having to do anything
fancy.
Writing a delegate to generate PKs from the database is not a bid
deal (see GVCEOFExtensions for an example of an integer PK caching
delegate).
BTW - Thanks to everyone - especially Chuck and Sasha - for all you
help so far. I definitely would not even be asking this question if
it wasn't for all of your help and advice. I hope someday to be a
contributor and help some poor newbie like me! :-) Thank You!
Flattery will get you everywhere ;-)
