Description (last modified by )
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.
