Hur konfigurerar man Postgresql med rails-projekt?

Har du angett ett lösenord för din postgres användare?

I din config/database.yml du bör ha dina databaser korrekt inställda:

development:
  adapter: postgresql
  encoding: unicode
  database: your_app_development # name your development app something
  host: localhost
  pool: 5
  username: your_username
  password: your_password # or leave blank if you didn't set a password

test:
  adapter: postgresql
  encoding: unicode
  database: your_app_test
  host: localhost
  pool: 5
  username: your_username
  password: your_password
