✅

from django.core.files import File
import os

class Item(models.Model):
    image_file = models.ImageField(upload_to='images')
    image_url = models.URLField()

...

def get_remote_image(self):
    if self.image_url and not self.image_file:
        result = urllib.urlretrieve(self.image_url)
        self.image_file.save(
                os.path.basename(self.image_url),
                File(open(result[0]))
                )
        self.save()

You can override the default save() method to automatically invoke get_remote_image().

from django.db import models
from django.core.files import File
from urllib.request import urlopen
from tempfile import NamedTemporaryFile

class Item(models.Model):
    image_file = models.ImageField(upload_to='images')
    image_url = models.URLField()

...

def get_remote_image(self):
    if self.image_url and not self.image_file:
        img_temp = NamedTemporaryFile(delete=True)
        img_temp.write(urlopen(self.image_url).read())
        img_temp.flush()
        self.image_file.save(f"image_{self.pk}", File(img_temp))
    self.save()

This solution avoid any utf-8 errors received during url process.

It works only with python 3.6+ because the f string.

For python3

from django.core.files import File
from urllib import request
import os

class Item(models.Model):
    image_file = models.ImageField(upload_to='images')
    image_url = models.URLField()

...

def get_remote_image(self):
    if self.image_url and not self.image_file:
        result = request.urlretrieve(self.image_url)
        self.image_file.save(
                os.path.basename(self.image_url),
                File(open(result[0], 'rb'))
                )
        self.save()

Python3

from django.db import models
from django.core.files import File
from urllib.request import urlopen
from tempfile import NamedTemporaryFile

class Item(models.Model):
    image_file = models.ImageField(upload_to='images')
    image_url = models.URLField()

    def save(self, *args, **kwargs):
        if self.image_url and not self.image_file:
            img_temp = NamedTemporaryFile(delete=True)
            img_temp.write(urlopen(self.image_url).read())
            img_temp.flush()
            self.image_file.save(f"image_{self.pk}", File(img_temp))
        super(Item, self).save(*args, **kwargs)

It`s similar but with automated save ‘image_file’, when add ‘image_url’
