There are oranges and there are apples. oranges are arbitrary foreign keys. The problem here is not implementing them in the DAL. this could be done in a couple of lines of code. The problem is 1) is this good practice? I think no. 2) how should SQLFORMs handle this?
apples are "polymorphic references". You can do this using "integer". I do not see the need for defining another keyword unless you want to make web2py aware that this integer contains a polymorphic reference. Assuming this were possible (and it is not in an easy way), what would you like the DAL to do with it? Massimo On Sep 6, 5:02 pm, Joe Barnhart <[email protected]> wrote: > OK, I'm confused.
