<div dir="ltr">For a ticketing system, you could just use the unix timestamp as the ticket id. <br><font face="Courier New, Courier, mono"><strong><br>269-345-460 is my birthday... ( July 15, 1978)<br></strong></font><strong><font size="-1" face="Courier New, Courier, mono"><font color="#cc0000">121-873-549-7 is now.</font></font></strong> (well, when this email was written).<br>
<br>Anyway, these should be pretty easy to give over the phone. They are unique enough that you can take 59 calls a minute, 3599 calls an hour. It can also save you from storing another value "ticket open date/time".<br>

Hi all. I'm playing with standalone ZODB at the moment trying to get a<br>
better understanding of its use in applications. I come from a<br>
PHP/MySQL background, and I'm taking my first steps with Python at the<br>
same time.<br>
<br>
One of the things I'm not understanding about ZODB is assigning<br>
incremental IDs to objects. For instance, if I were to be writing a<br>
support-ticket system I'd want to give each ticket a unique number,<br>
but one that's "human-useable" (otherwise you could just use a UUID -<br>
try giving one of those over the phone!).<br>
<br>
Also, how would one add a new item to the db in this way?<br>
<br>
For instance:<br>
<br>
class Ticket(Persistence):<br>
def __init__(self):<br>
<a href="http://self.id" target="_blank">self.id</a> = '' # How do I add a new incremental ID here?<br>
<br>
# and later on in the app<br>
<br>
tkt = Ticket()<br>
dbroot[?????] = tkt<br>
<br>
How would one assign a unique ID to the root at that point?<br>
