Meta field get_latest_by does not support fields with a - (Do get decending order)

[Shabda]

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,

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

class Meta:

get_latest_by = '-ordering'

and do FeaturedPage.objects.latest(),
It raises OperationalError.
