6366	Meta field get_latest_by does not support fields with a - (Do get decending order)	Shabda	nobody	"Model objects have a order_by method to order, which can take arguments of the form '-attribute_name' to get descending order ordering. This syntax is not supported by get_latest_by in Meta.

Code to validate this,

{{{
#!python
class FeaturedPage(models.Model):
    ordering = models.IntegerField(default = 0, unique = True)

featured_pages = FeaturedPage.objects.all().order_by('-ordering')
}}}

This works, but if you add 

{{{
#!python
    class Meta:
        get_latest_by = '-ordering'
}}}
and do FeaturedPage.objects.latest(),
It raises OperationalError."		closed	Core (Other)	dev		invalid	Models, Meta	shabda.raaj@…	Unreviewed	0	0	0	0	0	0
