I have 2 models

class Vhost(models.Model):
    dns = models.ForeignKey(DNS)
    user = models.ForeignKey(User)
    extra = models.TextField()


class ApplicationInstalled(models.Model):
    user = models.ForeignKey(User)
    added = models.DateTimeField(auto_now_add=True)
    app = models.ForeignKey(Application)
    ver = models.ForeignKey(ApplicationVersion)
    vhost = models.ForeignKey(Vhost)
    path = models.CharField(max_length=100, default="/")


    def delete(self):

        #
        # remove the files
        #
        print "need to remove some files"


        super(ApplicationInstalled, self).delete()

If I do the following

>>> vhost = Vhost.objects.get(id=10)
>>> vhost.id
10L
>>> ApplicationInstalled.objects.filter(vhost=vhost)
[<ApplicationInstalled: http://wiki.jy.com/>]
>>> vhost.delete()
>>> ApplicationInstalled.objects.filter(vhost=vhost)
[]

As you can see there is an applicationinstalled object linked to vhost but when I delete the vhost, the applicationinstalled object is gone but the print never gets called.

Any easy way to do this without iterating through the objects in the vhost delete?
