Django 中的 STATIC_ROOT 设置

Question

I am learning Django and have built a sample Django app. It works fine on my computer, but I am having trouble deploying it to Heroku. My root directory has the following structure:

My setttings.py file has the following settings for static files:

STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, "static")
]
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

The full settings.py file is following:

    """
Django settings for firstdjango project.

Generated by 'django-admin startproject' using Django 1.8.

For more information on this file, see
https://docs.djangoproject.com/en/1.8/topics/settings/

When I try to deploy to Heroku, I get the following error message:

ImproperlyConfigured:You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path

Answer 1

Here are the recommended settings for static root for a django -> heroku project

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.11/howto/static-files/    

STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
STATIC_URL = '/static/'    

# Extra places for collectstatic to find static files.
STATICFILES_DIRS = [
    os.path.join(PROJECT_ROOT, 'static'),
]

I would recommend just using this https://github.com/heroku/heroku-django-template as a starting point and import your apps into that project. Due to the fact (as of now) that Heroku recommends using the following packages

Gunicorn 
WhiteNoise
dj-database-url

The git project will provide you with "Production-ready configuration for Static Files, Database Settings, Gunicorn, etc." In other words, it will give you the correct configuration to deploy Django to Heroku.
