Ok, yeah I suppose that would save storage space and bandwidth
considering the fact I have a few copied of the same email (From my sent
folder and I'm getting some emails twice).
the time last modified on the latest object that has a foreign key to it.
So when I made a new document, in the admin interface I see April 11, 2013,
8:24 p.m. for the Created column and 2013-04-11 20:24:36.799167 for the Last
Modified column.
Also I can click to sort the results by Created date, but not by last
modified date.
I'm afraid any reason why it's different. Are you using your own ModelAdmin ?
class DocAdmin(admin.ModelAdmin):
list_display = ['name','created','last_modified']
Additionally in the same file in the model method I am using a for-loop to
get the value for Last Modified. I imagine going through each object just to
pull the data from the last one isn't very efficient and pretty redundant. I
tried to just pull the last object directly but am getting an error:
I modified your code accordingly http://pastebin.com/7NisAVfN
be aware that if a 'Piece' matching that criteria doesn't exists, it
will raise a DoesNotExist exception, maybe you'll want to catch it.

Hmm so it was caused by a Document with no pieces. The code you provided
simply returned None for that one :)
Thanks,
Mike
