Actually, my advice was subtly different.
anyone got a hint on a slice of code to do that short url magic?
if I were to start now, I guess I'd wait for the object to store in the DB, get
the primary key integer and modular arithmetically pick a character from a set
and add that to a character lineup which should reflect a unique choice
Yep, all depends on the number of potential collisions you care about. In
semi-controlled environments you can make do with fewer bits of uniqueness.

oh, ya, I hadn't seen that class but the idea is similar.
I guess because I was using the app not database, I put in an instance number
or something about the host/port or something.
this brings me to my next question --

You're close to a real uuid at that point. The common problem is multiple

value since you're probably coordinating there anyway. But it all depends on
your app, your db, your scaling characteristics, how many potentia
Hi Travis-
Is it impractical?
I've used a simple date+rand constructor and ran it through an encoding to HEX
to get a 'random' object id and had no troubles with that. I suppose it has
limits to uniqueness in theory but it was quick to generate.
I was also about to start looking for something
Unless you're generating a true guid that's impractical to do in a general way
at the app level.

Hi Everyone,
Thanks for all of your suggestions.
The general consensus seems to be don't use primary keys in the way I
described, use another unique identifier/slug etc. But if one really, really
has to; then the following are available:
EOUtilities.faultWithPrimaryKey
EOUtilities.faultWithPrim
Just to clarify slightly, I happen to agree with Dave and Jesse, but that's
almost incidental to your original post. When I wrote this:

Plus 1.
If your business logic does not require using keys as logic then you likely
want a generated unique id alongside your key.
There's a lot of reasons but some are that relational database keys have
complicated, even obtuse logic that can vary between database and even
versions.

My suggestion would be that you don't. Calling it a best practice isn't an
arbitrary designatio

Hi,
Since the best practice is to not make primary keys class properties, how do I
then create a qualifier that is based on the primary key of an EO?
Simple Eg: A blog site has nice, short bookmark-able URLs like
http://website.com/blog?id=5 where 5 is the primary key. When the user hits
that p
