django 에서 static file이 나오지 않을때

django 에서 static file이 나오지 않을때 아래와 같이 설정하면 된다.

wsgi.py 를 반드시 설정하자.

Django settings for static assets can be a bit difficult to configure and debug. However, if you just add the following settings to your settings.py, everything should work exactly as expected:

settings.py

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.7/howto/static-files/

BASE_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = 'staticfiles'
STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

Django won’t automatically create the target directory that collectstatic uses, so we recommend adding a dummy file to your repository, as seen here.

Whitenoise

By default, Django does not support serving static files in production. We recommend using theWhiteNoise project for best-practice serving of static assets in production.

Installing Whitenoise

$ pip install whitenoise
...
$ pip freeze > requirements.txt

settings.py

# Simplified static file serving.
# https://warehouse.python.org/project/whitenoise/

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

wsgi.py

from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

Your application will now serve static assets directly from Gunicorn in production. This will be perfectly adequate for most applications, but top-tier applications may want to explore using a CDN with Django-Storages.

Automatic Collectstatic

When a Django application is deployed to Heroku, collectstatic is run automatically when it is configured properly.

Detection

We determine if collectstatic is configured by running the following against your codebase:

$ python manage.py collectstatic --dry-run --noinput

If required configurations are missing, this command will fail and no collectstatic support will be applied to your application.
