def upload_to(instance, filename): 
    filename = time.strftime('%Y%m%d%H%M%S') 
    ym = time.strftime('%Y%m') 
    return 'uploads/%s/%s.jpg' % (ym,filename) 

class Person(models.Model): 
    first_name = models.CharField(max_length=30) 
    last_name = models.CharField(max_length=30) 

    photo = models.ImageField(u"Image (Upload)",upload_to=upload_to) 
    company = models.ForeignKey('Company') 

    def image(self): 
     if self.photo: 
      return FileObject(self.photo.name) 
     return None 


class Company(models.Model): 
    name = models.CharField(max_length=30) 
    def __unicode__(self): 
     return self.name 

오류로 'PersonAdmin.fields'에서 누락 된 'image_thumbnail를'필드를 참조하는 방법 형태.

어떻게 당신은 photo에 image_thumbnail하지를 참조해야이
