Download a remote image and save it to a Django model

Question

I am writing a Django app which will fetch all images of particular URL and save them in the database.

But I am not getting on how to use ImageField in Django.

Similar to @boltsfrombluesky's answer above you can do this in Python 3 without any external dependencies like so:

from os.path import basename
import urllib.request
from urllib.parse import urlparse
import tempfile

from django.core.files.base import File

def handle_upload_url_file(url, obj):
    img_temp = tempfile.NamedTemporaryFile(delete=True)
    req = urllib.request.Request(
        url, data=None,
        headers={
            'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'
        }
    )
    with urllib.request.urlopen(req) as response:
        img_temp.write(response.read())
    img_temp.flush()
    filename = basename(urlparse(url).path)
    result = obj.image.save(filename, File(img_temp))
    img_temp.close()
    return result
