I recently switched a bunch of
{{{
ordering = ["name"]
}}}
to
{{{
ordering = [Lower("name")]
}}}
in the Meta class of some models.
Now when I order a related Model, the result is not order as it should be.
Consider the following example:
{{{
class ItemCategory(models.Model):
name = models.CharField(max_length=100)
class Meta:
ordering = [Lower("name")]
class Item(models.Model):
name = models.CharField(max_length=100)
category = models.ForeignKey("ItemCategory", blank=True, null=True,
on_delete=models.CASCADE)
class Meta:
ordering = [Lower("name")]
}}}
If I do `Item.objects.all().order_by("category", "name")` then the results
are ordered by Item name only, not ItemCategory name and Item name as it
should be.
