Django cropper - getting additional resized images from cropped image -

i have problem getting additional resized images croped image. using django-cropper 0.1. model cropped image have part of code this:

class cropped(models.model):     def __unicode__(self):         return u'%s-%sx%s' % (self.original, self.w, self.h)      def upload_image(self, filename):         return '%s/crop-%s' % (settings.root, filename)      def save(self, *args, **kwargs): #force_insert=false, force_update=false, using=none):         source = self.original.image.path         target = self.upload_image(os.path.basename(source))          image.open(source).crop([             self.x,             # left             self.y,             # top             self.x + self.w,    # right             self.y + self.h     # bottom         ]).save(django_settings.media_root + os.sep + target)           self.image = target                 super(cropped, self).save(*args, **kwargs) 

but want have additional resized images cropped image change code little , looks that:

class cropped(models.model):     def __unicode__(self):         return u'%s-%sx%s' % (self.original, self.w, self.h)      def _get_average_path(self):         return _add_average(self.path)     average_path = property(_get_average_path)      def _get_average_url(self):         return _add_average(self.url)     average_url = property(_get_average_url)      def _get_large_path(self):         return _add_large(self.path)     large_path = property(_get_large_path)      def _get_large_url(self):         return _add_large(self.url)     large_url = property(_get_large_url)      def upload_image(self, filename):         return '%s/crop-%s' % (settings.root, filename)      def save(self, *args, **kwargs): #force_insert=false, force_update=false, using=none):         source = self.original.image.path         target = self.upload_image(os.path.basename(source))          img = image.open(source).crop([             self.x,             # left             self.y,             # top             self.x + self.w,    # right             self.y + self.h     # bottom         ]).save(django_settings.media_root + os.sep + target)          self.image = target                 super(cropped, self).save(*args, **kwargs)         img = image.open(self.image.path)         img = img.resize((180, 180), image.antialias)         img.save(self.large_path, 'jpeg')          img = img.resize((104, 104), image.antialias)         img.save(self.average_path, 'jpeg')  

but still doing basic job. can me , give suggestion of should fix in code?

i answer own question because found solution , maybe someone. maybe best solution, works. first needed add additional field additional, resized image:

average = models.imagefield(     blank=true, null=true,     verbose_name = _('image'),     upload_to    = upload_image,     editable     = false, ) 

then needed chnge save() method this:

 def save(self, *args, **kwargs): #force_insert=false, force_update=false, using=none):         source = self.original.image.path         target = self.upload_image(os.path.basename(source))          image.open(source).crop([             self.x,             # left             self.y,             # top             self.x + self.w,    # right             self.y + self.h     # bottom         ]).save(django_settings.media_root + os.sep + target)         self.image = target          splited_target = target.split("/")         avepath = "/average-".join(splited_target)          self.average = avepath          image.open(self.image).resize((104, 104), image.antialias).save(django_settings.media_root + avepath, 'jpeg')         super(cropped, self).save(*args, **kwargs) 

and all.
