Django 1.3.1 Heroku Postgres error - django

Question

We recently pushed our site to staging and have been struggling to get it up ever since, and the team at Heroku are not really responding in time, so I am turning to the community to see if there is a quick fix.
We scrapped the old one and set up a new stack still with the same issues
heroku config
DISABLE_INJECTION: 1
settings.py
import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'mydb',
'USER': 'myuser',
'PASSWORD': 'mypassword',
'PORT': '',
'HOST': 'localhost'
},
}
Here is the full trace.
heroku run python myapp/manage.py syncdb

Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?

Answer 1

DATABASES = {
'default': dj_database_url.config(default=os.environ.get('DATABASE_URL'))
}

Answer 2

Make sure you have Postgres on your heroku:
heroku addons:add heroku-postgresql:dev
Figure out database url env variable. It's going to look something like this : HEROKU_POSTGRESQL__URL
heroku config | grep POSTGRESQL
Update your settings
import dj_database_url
import os
POSTGRES_URL = "HEROKU_POSTGRESQL_<COLOR>_URL"
DATABASES = {'default': dj_database_url.config(default=os.environ[POSTGRES_URL])}
Bob is your uncle.
I put together a handy bootstrap for django on heroku. It might be helpful: https://github.com/callmephilip/django-heroku-bootstrap
Happy deploying

Answer 3

Try this:
import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://myuser:mypassword#localhost:5432/mydb')}
