Hi,
We were not able to reproduce an example described in Django's documentation, concerning the value() method of Queryset.
>>> from django.db.models import Count
>>> Blog.objects.values('author', entries=Count('entry'))
<QuerySet [{'author': 1, 'entries': 20}, {'author': 1, 'entries': 13}]>
When executing above lines with the fixtures described in the docs, we get the following error:
django.core.exceptions.FieldError: Cannot resolve keyword 'author' into field. Choices are: entries, entry, id, name, tagline
This second example from the documentation doesn't seem to work either:
>>> Blog.objects.values('author').annotate(entries=Count('entry'))
<QuerySet [{'author': 1, 'entries': 33}]>
Did we miss something ?
Is the django documentation accurate here ? We wonder how a Blog object could have an 'author' field, given its model definition.
Please find attached a minimal project with unittests reproducing these issues.
Sincerely,
Joseph Lucas

Confirmed. I opened a bug report: https://code.djangoproject.com/ticket/29032.
