10738	ContentType and model instances with deferred fields	tomasz.elendt	nobody	"Suppose we have model like this:

{{{
class Entry(models.Model):
    title = models.CharField(max_length=128)
    body = models.TextField()
}}}

{{{
>>> from blog.models import Entry
>>> # creating new entry object
>>> Entry.objects.create(title=""test entry"", body=""some body content"")
>>> entry_1 = Entry.objects.get(title=""test entry"")
>>> entry_2 = Entry.objects.defer('body').get(title=""test entry"")
>>> from django.contrib.contenttypes.models import ContentType
>>> ContentType.objects.get_for_model(e1)
<ContentType: entry>
>>> ContentType.objects.get_for_model(e2)
<ContentType: entry_ deferred_body>
}}}

`ContentTypes` for the same model instances with and without deferred fields are not the same (I suppose that's because they're not instances of the same class and have different `_meta.object.name` value). I'm not sure if that's the correct behavior. I mean - does the instance with deferred field(s) should have different `ContentType`?

I found this issue when i tried use django-tagging and it's template tag `tags_for_object` with 'deferred `QuerySet`'. But maybe described behavior is correct and that's django-tagging bug?"		closed	Database layer (models, ORM)	1.1-beta		fixed			Unreviewed	1	0	0	0	0	0
