Django Deployment With Heroku
django, heroku
Solution
This is one point where I'm a bit confused, the walkthrough made no mention of what happens with my existing db settings, leave as is, remove, change?
I too followed their walkthrough and had the same problems. For me it was the DATABASES statement that made the error. I replaced my database configuration with the one they provide, while it must just be added to the dictionary already created by your database settings. So instead of replacing your database statement just add:
DATABASES['default'] = dj_database_url.config()
Problem
I'm trying to deploy my existing django project with heroku, following the walk through provided by heroku and adapting as needed to be specific to my project. Just to run quickly through what I've done so far: - installed django-toolbelt in my virtualenv created a Procfile in the root of my project named `Procile` which includes: ``` web: gunicorn projectname.wsgi ``` using `foreman start` confirmed that my project still ran properly locally - created `requirements.txt` using `pip freeze` and placed it in the root of my project added the following to `settings.py`: ``` import dj_database_url DATABASES['default'] = dj_database_url.config() # Honor the 'X-Forwarded-Proto' header for request.is_secure() SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') # Allow all host headers ALLOWED_HOSTS = ['*'] # Static asset configuration import os BASE_DIR = os.path.dirname(os.path.abspath(__file__)) STATIC_ROOT = 'staticfiles' STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) ``` This is one point where I'm a bit confused, the walkthrough made no mention of what happens with my existing db settings, leave as is, remove, change? Added the following to wsgi.py: ``` from django.core.wsgi import get_wsgi_application from dj_static import Cling application = Cling(get_wsgi_application()) ``` added heroku as a git remote and pushed my project to heroku. It worked. - `heroku ps:scale web=1` However, when I try to access my project I get an `Application Error`. When I check the status with heroku `heroku ps --app projectname` it says the dyno has crashed. Restarting does nothing. `heroku logs --app projectname` yields: ``` 2013-07-18T00:01:14.246956+00:00 heroku[web.1]: Starting process with command `gunicorn projectname.wsgi`
