Description
Invalid field values when you use select_related() and defer().
See sample below.
May be it clashes with ticket #11606
#models.py
class Author(models.Model): name = models.CharField(max_length=20, default='author') text1 = models.CharField(default='text1', max_length=10) text2 = models.CharField(default='text2', max_length=10) def __unicode__(self): return u'%s' % self.name class Work(models.Model): name = models.CharField(max_length=20, default='work') author = models.ForeignKey(Author) def __unicode__(self): return u'%s' % self.name
#manage.py shell
from test.myapp.models import * a = Author() a.save() w = Work() w.author = a w.save() w = Work.objects.filter(id=1).select_related('author').defer('author__text1')[0] print w.author.text1 >> u'text2' !!! ERROR

Possibly, the same bug as in #10733?
