Hi,

in the past I've written to this list re using the django db back-end as
a db access layer for a test-automation system I work on; we hope to
re-write the current front-end with django at some point.

We're a little closer to experimenting with this, and have another question:
is there any coherency checking/row (table?) locking implemented in
django's db layer?

i.e. if I have two scripts, on two different machines, both accessing
the same db & table, what built in support is there to catch
race-conditions/invalid updates/etc?  Are there any examples out there
someone can point me to? Also, is there any difference with which db is
used- MySql vs Postgres?

So far we've found nothing by searching; I suspect we're using the wrong
terminology...


(Background: We are hoping to re-write the front-end web-gui in Django
(current one is difficult to maintain, and hard for new developers), and
as the backend (scheduler, always running) is in python and has an
'interesting'- i.e. slightly broken- db layer, we're thinking to fix to
problems by taking advantage of django.)

Thanks in advance,

Julian
