Django static files on heroku

Question

I deployed a django app to heroku, using "git push heroku master" which worked absolutely fine.

I then created a second app on the same git using "heroku create second-app -r staging'

and pushed using: git push staging master

when I open second-app, none of the static files are picked up or loaded (ie no css, js, or images work)

This is extremely confusing - please help!

my settings file is below

import os
import platform
import dj_database_url

DEBUG = True
TEMPLATE_DEBUG = DEBUG

# This should work for any deployment
BASE_DIR = os.path.abspath(os.path.join(os.path.dirname( __file__ ), '..'))

Update

I took a copy of the code and redeployed, which worked with the following updates to the settings:

STATIC_ROOT = 'staticfiles'

STATIC_URL = '/static/'

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


STATICFILES_FINDERS = (

    #'django.contrib.staticfiles.finders.FileSystemFinder',
    #'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    #'django.contrib.staticfiles.finders.DefaultStorageFinder',
)

I then branched my code (so I have master and staging) and synced new heroku remote into my staging branch. I then did a git push staging staging:master and it did a full upload; which has once again got me back to the same place... help!!!

Answer 1

Eventually solved this using the below in my urls file - from this question: Heroku - Handling static files in Django app

from <app> import settings
urlpatterns += patterns('',
        (r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.STATIC_ROOT}),
    )

Answer 2

I have been dealing with the same problem too. I tried not to use the solution recommended by David since it seems to be used only in development (and not production) (See: Heroku static files not loading, Django)

And here are the 2 things that I changed in my code.

(I'm using Django 1.7)

1) settings.py

I add these lines to the setting files

BASE_DIR = os.path.dirname(os.path.dirname(__file__))
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
TEMPLATE_DIRS = (
    os.path.join(BASE_DIR,  'templates'),
    # Add to this list all the locations containing your static files 
)

STATIC_ROOT: this tells Django where to (a) put the static files when you run "python manage.py collectstatic" and (b) find the static files when you run the application

TEMPLATE_DIRS: this tells Django where to look for your static files when it search for statics files when you run "python manage.py collectstatic"

2) wsgi.py

Originally my file was:

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "xxxx.settings")

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

And I changed it to:

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "xxxx.settings")

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

Read here for more information on whitenoise: https://devcenter.heroku.com/articles/django-assets#whitenoise

---

Also, remember to install whitenoise: pip install whitenoise==2.0.6

Before deploying the project, run: python manage.py collectstatic

This will create a folder indicated by STATIC_ROOT (declared in your settings.py), containing all your static files.
