Django doesn't update the ImageField path

I am trying to upload a profile picture when model instance is being created. I want my profile picture to be stored in a folder, that is named according to the instance id, hence once the picture is uploaded I need to create a new dir and move the picture there.

I followed this, which suggests overriding the default save() method in the model, and this, that proposes to use post_save signal to save the new file twice.

My current code looks as follows:

class Emp(models.Model): photo = models.ImageField("Photo", blank=True, null=True, default='default_avatar.png') def save(self, *args, **kwargs): # Call standard save super(Emp, self).save(*args, **kwargs) if self.photo.path: initial_path = self.photo.path new_path = os.path.join(settings.MEDIA_ROOT, 'profile_picture_of_emp_{0}/{1}'.format(self.pk, os.path.basename(initial_path))) # Create dir if necessary and move file if not os.path.exists(os.path.dirname(new_path)): os.makedirs(os.path.dirname(new_path)) os.rename(initial_path, new_path) # Save changes super(Emp, self).save(*args, **kwargs) 

So this actually moves the file and creates new_path correctly, however, the self.photo.path stills refers to the old location and I can't figure out a way to update this new path. The same happens with post_save signal as it doesn't update the path of moved file. Any suggestions?

Thanks!
