2199	[patch] Can't delete generic foreign key in Admin	parlar@…	Jacob	"Using the new generic foreign key stuff, I can't delete my foreign keys.

My model is as follows:

{{{
class AuthUser(models.Model):
    user = models.ForeignKey(User)
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    content_object = models.GenericForeignKey()
   
    class Admin:
        list_display = ('user', 'product_name')

    
    def product_name(self):
        return self.content_object.product_name
        

    def __str__(self):
        return self.user.username
        
class Product(models.Model):
    product_name = models.CharField(maxlength=64, blank=False, unique=True )
    users = models.GenericRelation(AuthUser)
}}}

After creating a few relations between Products and AuthUser (much like the Tag example given in the tests), I try to delete one of the AuthUsers via the Admin, and get the following:
