Strange effect of invalid ordering in qs-rf

[Petr Marhoun <petr.marhoun@…>]

I have tried very simple model (with 20 objects):

class A(models.Model):
    value = models.IntegerField()

And this code:

>>> A.objects.count()
20
>>> len(list(A.objects.order_by('value')))
20
>>> len(list(A.objects.order_by('nonsense'))) # Should it be an exception?
0
>>> A.objects.order_by('nonsense')
TypeError: Cannot resolve keyword 'nonsense' into field. Choices are: id, value

This is a cool error: when calling list(), Python tries to work with pre-iterator-protocol objects as well. Which means it quietly swallows TypeError (only). Sadly, that was precisely the exception we were raising in this case. I'm going to change the exception type to something less confusing. (Thanks to Jacob for guessing what was going wrong here.)
