Thanks for the response. I'm not sure if this exactly covers my case
but I like this feature. From the example given in the ticket:
def assigned_tasks():
return get_assigned_tasks_id_list(blah, blah)
class TimeRecord(models.Model):
task = models.ForeignKey(Task, limit_choices_to = {'id__in':
assigned_tasks})
I would like the assigned_tasks function to be have a reference to and
be able to calculate values based on the current instance of
TimeRecord. Perhaps that is what blah or blah are but I'm guessing
not.
Do I need to do something like work directly with newforms to achieve
something like this?
