18061	GenericRelation doesn't play well with proxy models	anonymous	nobody	"Take the following models:



{{{
class Person(models.Model):
    """"""
    Teenager (let's say this has the content type ID 1)
    """"""
    age = models.IntegerField()


class Teenager(Person):
    """"""
    Teenager (let's say this has the content type ID 2)
    """"""
    class Meta:
        proxy = True


class Pimple(models.Model):
    """"""
    A pimple.
    """"""
    content_type = models.ForeignKey(ContentType)
    object_id = models.IntegerField()
    content_object = generic.GenericForeignKey('content_type', 'object_id')
    color = models.CharField()
}}}


Now, if I create a {{{PimpleInline}}} on the {{{TeenagerAdmin}}}, and then create {{{Pimple}}} records with the main {{{PimpleAdmin}}}, setting the content type to {{{Teenager (ie, 2)}}}, you would think that a refresh on the {{{TeenagerAdmin}}} would reveal my new pimple in the inline list, but it doesn't. This has to do with the {{{GenericRelation.contrib_to_class}}} which attaches an updated queryset along the way, filtering by the content type of the proxy's parent model.
