Comment (by Josh):
Can we add an optional keyword argument to conditionally apply the
DISTINCT select? This just bit me on a production app.
Maybe something like:
{{{
account_manager = models.ForeignKey(
User,
limit_choices_to=Q(groups__name='Sales') | Q(groups__name='Admin'),
limit_choices_distinct=True, # default False
)
}}}
