I have the following model in my app, using the content-type django
framework in version 1.6.1 :
class GenericMedia(models.Model):
limit = models.Q(model = 'Image') | models.Q(model = 'Video') |
models.Q(model = 'Other')
content_type = models.ForeignKey(ContentType, limit_choices_to = limit)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey('content_type', 'object_id')
def __unicode__(self):
return u"%s" % os.path.basename(self.content_object.url.name)
def instance(self):
return self.content_object.__class__.__name__
class Media(models.Model):
description = models.CharField(blank = True, max_length = 500)
link = models.URLField(blank = True)
genericFK = generic.GenericRelation(GenericMedia,
content_type_field='content_type', object_id_field='object_id')
class Meta:
abstract = True
def __unicode__(self):
return u"%s" % os.path.basename(self.url.name)
def save(self, *args, **kwargs):
super(Media, self).save(*args, **kwargs)
generic_link = GenericMedia(content_object = self)
generic_link.save()
class Image(Media):
imgW = models.PositiveSmallIntegerField()
imgH = models.PositiveSmallIntegerField()
url = models.ImageField(upload_to = 'mediamanager', height_field = 'imgH',
width_field = 'imgW')
Everythings works fine, excepts the GenericRelation in my abstract Media Class.
In django documentation it is said that :
If you delete an object that has a GenericRelation, any objects which have a
GenericForeignKey pointing at it will be deleted as well.
But my problem is that when I delete an image (wich extends Media), the
GenericMedia pointing to it is not deleted.
If anyone has a solution, thanks !
