Django staticfiles not found on Heroku (with whitenoise)
Question: This question seems to be asked several time but I can not fix it.

I deployed a django app on production with `DEBUG = False`. I set my
`allowed_host`. I used `{% load static from staticfiles %}` to load static
files. I exactly write the settings sugested by Heroku doc :

    
    
    BASE_DIR = os.path.dirname(os.path.dirname(__file__))
    PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))
    
    STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
    STATIC_URL = '/static/'
    
    STATICFILES_DIRS = (
        os.path.join(PROJECT_ROOT, 'static'),
    )
    
    STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
    

BUT I got an error 500. And got this traceback (by mail)

    
    
    ...
    `cache_name = self.clean_name(self.hashed_name(name))
     File "/app/.heroku/python/lib/python3.5/site-    packages/django/contrib/staticfiles/storage.py", line 94, in hashed_name (clean_name, self))
    ...
    ValueError: The file ‘app/css/font.css’ could not be found with <whitenoise.django.GzipManifestStaticFilesStorage object at 0x7febf600a7f0>.`
    

When I run `heroku run python manage.py collectstatic --noinput` All seems ok
:

`276 static files copied to '/app/annuaire/staticfiles', 276 post-processed.`

Does anyone have an idea to help me, please ?

Thanks

EDIT :

    
    
    annuaire
    |-- /annuaire
    |-- -- /settings.py
    |-- /app
    |-- -- /static/...`
    

wsgi.py

    
    
    from django.core.wsgi import get_wsgi_application
    from whitenoise.django import DjangoWhiteNoise
    
    
    application = get_wsgi_application()
    application = DjangoWhiteNoise(application)
    


Answer: I got it. I needed to add python manage.py collectstatic --noinput; in my
Procfile. Heroku doc said that `collecticstatic` is automatically triggered.
