How to serve django static files on heroku with gunicorn

问题

I have an app in Django, I deployed it on heroku but I am unable to serve static files on the server and below are my code and settings:

settings.py

DEBUG = True
TEMPLATE_DEBUG = DEBUG
import os
PROJECT_PATH = os.path.abspath(os.path.dirname(__file__))
SITE_PATH = os.path.abspath(os.path.join(PROJECT_PATH, os.path.pardir))

STATIC_ROOT = ''
STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(SITE_PATH, 'staticfiles'),)
STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
#    'django.contrib.staticfiles.finders.DefaultStorageFinder',
)

urls.py

from django.conf import settings
from django.conf.urls import patterns, include, url
from polls.views import VoteClassBasedView
from django.contrib import admin
admin.autodiscover()


urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls')),
    url(r'^admin/', include(admin.site.urls)),
)

Procfile

web: gunicorn django_polls.wsgi

The above code is able to serve the the css files(Actually I integrated with bootstrap) on local machine, but after committing it to heroku git hub and running the url something like polls.herokuapp.com/polls/ , it is serving the html files and entire functionality but unable to serve the css file.

Also when I run the command foreman start it is also serving the static(css,js) files but the same code when deployed on heroku is unable to server the static files.

Can anyone please let me know what changes needs to be done in what files in order to deploy the Django app on the heroku?

Note, I had done R&D and applied various codes like using from django.contrib.staticfiles.urls import staticfiles_urlpatterns in the urls.py but unable to get the solution.

回答1:

While deploying your app first change DEBUG=FALSE in your setting file.

Following link can be useful.

To serve static files I highly recommend you to use whitenoise http://whitenoise.evans.io/en/stable/django.html

STATIC_ROOT = os.path.join(PROJECT_PATH, 'staticfiles')
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
MIDDLEWARE_CLASSES = [
  # 'django.middleware.security.SecurityMiddleware',
  'whitenoise.middleware.WhiteNoiseMiddleware',
  # ...
]

No need to run collectstatic as heroku will do that for you. What that does is puts all the files into the STATIC_ROOT for you (all compressed and with a hashed file name for long expires).
