Comment:
While adding this to {{{values()}}} is perfectly fine, doing the same with
{{{values_list()}}} feels weird. Also, it's buggy:
{{{#!python
# from ValuesListQuerySet in the patch
fields = list(self._fields) + self._aliased_fields.keys()
}}}
This makes the order of values in returned tuples depend on order of
dictionary keys, which is _undefined_. Just try:
{{{#!python
print Model.objects.values_list(a2="field", a3="other_field")
# on Python 2.7 and 3.2 values should be reversed.
}}}
