Re: How to import DoesNotExist exception ???
from tutorial part 03:
from django.http import Http404
# ...
def detail(request, poll_id):
try:
p = Poll.objects.get(pk=poll_id)
except Poll.DoesNotExist:
raise Http404
return render_to_response('polls/detail.html', {'poll': p})
but, you can use "get_object_or_404(, )"
shortcut and catch a http404 exception...
it's more clean =)

Re: ' Change History' for audit, compliance
Hi, You can use AuditTrail[1] (i'm using now) or django-revision[2] (i'm planning use this).

Re: Audit Trail
Hi Erick, It was working on r8339. I've updated django this morning to r8460 to and still working !! What is "history Manager" that you said ? look how i'm using audit trail: 1) i have my 'ordinary' model (without audit trail feature) 2) i get the audit trail code and drop it into site-packages python directory (it works if you put on root dir of your django project too) 3) put import line on your model 4) put an 'extra' attribute in your model (that i called 'history') to use audit trail. 5) and finnaly, run the magic command 'syncdb'.. or, sqlall , you should see all the sql generated by django. follows my (very) simple example: http://dpaste.com/hold/72943/ Try again with a simple example like that ... if did't work, send the error message... Good luck!!! ;) Sergio Durand erikcw escreveu: > Hi Sergio, > > I updated my code with your changes, and it still doesn't seem to be > working.

Audit Trail
Hi people, Finally i've got Audit Trail [1] working again !!! :) I'm not a django/python expert (i've started studying 2 months ago), but after fighting with "python manage.py validate" and searching in google, i've got the solution... the problem basically was missing **kwargs arguments in some handler functions (because changes made in r8223). Maybe this problem is very simple (in fact i think it is), but i've spent several hours (and learned a lot of things too) to get this working. This was my first code contribution and i'm very glad for that!!
