How to make a filefield image appear on the site?

Question

Django

Please tell me, I can not upload a photo from the admin panel.
It does not appear in the template.
Registered in the settings:

MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'media_cdn')
MEDIA_URL = '/media/'

and in urls.py:

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

The picture is displayed only in the admin panel itself when you click on the link.
Here is my model:

class Book(models.Model):
    image = models.FileField(blank = True, null=True)

Answer 1

<img src="{{ book.image.url }}" >

Answer 2

There is an ImageField for this.
