问题 I've got a form with profile_picture=ImageField field set to the initial value. It's using ClearableFileInput widget. I need to customize the form in the template, so I can't simply use {{ form.profile_picture}} .

This is achievable by using the django-extensions : https://django-extensions.readthedocs.io/en/latest

Also when I comment out STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' I don't get 500 error. I followed the documentation given in http://whitenoise.evans.io/en
