models.py 

class Anhang(models.Model):
    KN = models.IntegerField(unique=False)
    Thema = models.CharField(max_length=100, blank=True, unique=False)
    Username = models.CharField(max_length=100, blank=True, unique=False)
    Password = models.CharField(max_length=100, blank=True, unique=False)
    Email = models.CharField(max_length=100, blank=True, unique=False)
    Anhang = models.CharField(max_length=250, blank=True, unique=False)


class Kunden(models.Model):
    KN = models.IntegerField(unique=True)
    Anrede = models.CharField(max_length=30, blank=True)
    Name = models.CharField(max_length=30, blank=True)
    Vorname = models.CharField(max_length=30, blank=True)
    Infos = models.CharField(max_length=250, default='Notiz:', editable=True)

так ... все мои delete_views работают за исключением этого, потому что обычно они имеют свой источник из "Kunden.id", но этот delete_view ориентируется на Anhang.KN настолько, насколько я думаю, и я не знаю, где проблема ...
