copy - Dupicate an ImageField in another field of same model while saving the model objects -

i want upload 1 image(location of stores in photo field of model mentioned below ) , want duplicate photo field thumbnail programitically.

i tried in way mentioned in class picture(models.model): below. bytheway resizedimagefield works , have tested photo field. needed overwrite def save(self, *args, **kwargs): method mentioned below.

from django_resized import resizedimagefield  class picture(models.model):     photo = resizedimagefield('photo', upload_to='photos/%y/%m/%d', size=[636,331])     thumbnail = resizedimagefield('thumbnail', upload_to='thumbnail/%y/%m/%d', size=[150, 100], blank=true, null=true)      def save(self, *args, **kwargs):         super(picture, self).save(*args, **kwargs)         if self.photo:             self.thumbnail = resizedimagefield(self.photo)             self.thumbnail.save() 

i think problem save method calling on self.thumbnail.save(), try instead:

def save(self, *args, **kwargs):     if self.photo:         self.thumbnail = resizedimagefield(self.photo)     super(picture, self).save(*args, **kwargs)
