I currently have Ruby on Rails installed via RVM in Ubuntu 12.04. The default database is set up in SQLite3, but I'd like to switch to PostgreSQL for the purposes of pushing to Heroku. How can I accomplish this?
Here are the steps I've followed:
Install PostgreSQL and development package
$ sudo apt-get install postgresql
$ sudo apt-get install libpq-dev
Set up a user that is the same as my Ubuntu log-in
$ sudo su postgres -c psql
postgres=# CREATE ROLE <username> SUPERUSER LOGIN;
postgres=# \q
Modify Gemfile
# Remove gem 'sqlite3'
gem 'pg'
Modify database.yml
in app directory
development:
adapter: postgresql
encoding: unicode
database: appname_development
pool: 5
timeout: 5000
username: <username>
password:
test:
adapter: postgresql
encoding: unicode
database: appname_test
pool: 5
timeout: 5000
username: <username>
password:
Run bundle install
$ bundle install
Create databases and migrations
$ rake db:create:all
$ rake db:migrate
