Django Whitenoise 500 server error in non debug mode

问题

I am using django in my local machine. In order to serve the static files I used WhiteNoise along with it. When DEBUG = True all static files are correctly served. But when I changed DEBUG = False and set ALLOWED_HOSTS = ['*'] I'm getting 500 server error. However admin site loads without any error. 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/stable/django.html to connect whitenoise. I haven't made any changes to wsgi.py file. I ran python manage.py collecststatic and it ran without any errors.

The settings.py is given below:

import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

SECRET_KEY = 'fdft&b(xb*!qq3ghjkjhg6789ih8ik!w10$0uscxcpqpmz'

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

回答1:

I had a similar error and the logs said ValueError: Missing staticfiles manifest entry for...

Changing STATICFILES_STORAGE in settings.py from:
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
to:
STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage'
as described in this section of whitenoise docs fixed it for me.

Also you probably want to change your SECRET_KEY now that it's shared publicly.

Change for fast solution:

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

to:

STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage'

But! It will generate static files without unique chunk keys for correct updating in client browser (e.g. style.343a1fa2da70.css) and client won't see changes after without refreshing site cache. WhiteNoise only adds a thin wrapper around Django’s storage to add compression support, and because the compression code is very simple it generally doesn’t cause problems. So you need

1. Return STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
2. Clear staticfiles folder manually
3. Refresh static assets by py manage.py collectstatic --noinput
4. Enjoy!
