为什么我的 static 文件在部署到 Heroku 服务器时无法提供服务？ （姜戈）

Question

So this is a common mistake for Django users, which is static files not served in production when Debug=False . I've tried many methods to overcome this issue, but still cannot figure out right solution. Below is my settings.py

...
DEBUG = False

MIDDLEWARE = [
    'whitenoise.middleware.WhiteNoiseMiddleware',
    ...
]
...

STATIC_URL = '/static/'
STATICFILES_DIRS = [ 
    os.path.join(BASE_DIR, 'static'), 
    os.path.join(BASE_DIR, 'main/static'),
    os.path.join(BASE_DIR, 'member/static'),
    os.path.join(BASE_DIR, 'register/static'),
]

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

STATICFILES_FINDERS = [
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
]

I don't see how I've done wrong.

*One thing that might be a potential cause is that I've set DISABLE_COLLECTSTATIC=1 since the initial deploy to heroku server.

Try this:

1. Add to your setting.py installed apps 'whitenoise.runserver_nostatic' .
2. Add to your setting.py MIDDLEWARE 'whitenoise.middleware.WhiteNoiseMiddleware'
3. Add to your seeting.py these 3 lines

STATIC_URL = '/static/'
STATICFILES_DIRS = (str(BASE_DIR.joinpath('static')),)
STATIC_ROOT = str(BASE_DIR.joinpath('staticfiles'))
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' # new
django_heroku.settings(locals())

for the last line here you need to install django_heroku (not django_on_heroku , be careful)

PS if after this it fails because it can't find the staticfiles folder, manually create it. You have to do it only once and that's it. An empty folder and nothing more.
