Hi.
I have a query I am trying to perform in the ORM and I'm not sure how to do
it.
I have two models: Target and Property with a one-to-many relationship. One
Target can have many Properties.
I want to list all targets along with their latest properties (as stored
under Property.export_date) so

link
The first one uses a jquery plugin that's discontinued and the second one
works only in the admin.
Also, I feel I'm missing something that's not so complex...

if hasattr(value, 'name'):
v = value.name
else:
v = Non
