Posted 2021-05-08

from django.core.files.base import ContentFile
import os

source_attachment = source_obj.source_attachment
filecontent = ContentFile(source_attachment.file.read())
filename = os.path.split(source_attachment.file.name)[-1]

target_obj.target_attachment.save(filename, filecontent)
target_obj.save()

# VERY IMPORTANT !
source_attachment.file.close()
