Changes between Initial Version and Version 1 of Ticket #6366

-              initial
+              v1
 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.
