Python database WITHOUT using Django (for Heroku)

Question

To my surprise, I haven\'t found this question asked elsewhere. Short version, I\'m writing an app that I plan to deploy to the cloud (probably using Heroku), which will do var

Answer 1

You can get a database provided from Heroku without requiring your app to use Django. To do so:

heroku addons:add heroku-postgresql:dev

If you need a larger more dedicated database, you can examine the plans at Heroku Postgres

Within your requirements.txt you'll want to add:

psycopg2

Then you can connect/interact with it similar to the following:

import psycopg2
import os
import urlparse

urlparse.uses_netloc.append('postgres')
url = urlparse.urlparse(os.environ['DATABASE_URL'])

conn = psycopg2.connect("dbname=%s user=%s password=%s host=%s " % (url.path[1:], url.username, url.password, url.hostname))
cur = conn.cursor()

query = "SELECT ...."
cur.execute(query)
