Back to the topic of things which, unlike well-reasoned community
advocacy, I can actually do well, I have been slowly constructing a
blog entry that walks through the "polymorph.py" example I recently
added. This example illustrates something that a few people asked
for, which is the ability to make a single relation that loads
multiple types of objects. A little bit of rubber-malleting around
the code enabled a reasonable approach that uses UNIONS to be
produced, which I think is more appropriate for loading distinct
types of data in one query rather than a JOIN (but you could do it
with a JOIN as well if you wanted).
anyway, the blog entry is at http://techspot.zzzeek.org/ . It would
probably be helpful for everyone if I wrote more of these, but they
are time-consuming to produce...hope you enjoy it.
