Eğer postresql sunucunuzdaki sonra sadece ana bilgisayar yüklü: veritabanına localhost.yml, ben genellikle nerede yazıyor havuzun etrafında: at 5. Aksi takdirde localhost değilse kesinlikle veritabanını nerede bu uygulama söyle.

development:
  adapter: postgresql
  encoding: unicode
  database: kickrstack_development
  host: localhost
  pool: 5
  username: kickrstack
  password: secret

Kullanıcı kimlik bilgilerinizi doğru bir veritabanı oluşturmak ve uygulamanızın bağlantı kurmak için bir kullanıcı sahiplik atayarak ayarlandığından emin olun. Postgresql 9 vadede yeni bir kullanıcı oluşturmak için:

sudo -u postgres psql

eğer sadece ters eğik çizgi şifre var mi, yok eğer postgresql kullanıcı parolasını ayarlayın.

postgres=# \password

Yeni bir kullanıcı oluşturmak ve bir parola ve kullanıcı yeni veritabanı:

postgres=# create user "guy_on_stackoverflow" with password 'keepitonthedl';
postgres=# create database "dcaclab_development" owner "guy_on_stackoverflow"; 

Şimdi veritabanı güncellemesi.yml veritabanı kullanıcı oluşturma doğruladı, şifre ve bu yetkileri ayarladıktan sonra dosya. Ana unutma: localhost.
