Railsでデータベースに接続できなくてエラーがでる

Last updated at Posted at 2014-08-30

vagrant環境で作っているRailsプロジェクトでHelloWorldしようとしたらエラーがでました。postgresqlを使用しています。

ActiveRecord::NoDatabaseError (FATAL:  role "vagrant" does not exist
Run `$ bin/rake db:create db:migrate` to create your database):

ボクの環境ではpostgresqlにはvagrantというユーザーはいません。なのでdatabase.ymlでuser_nameを指定しました。

database.yml
default: &default
  adapter: postgresql
  encoding: unicode
  username: user_name
  password:

エラーが出なくなりました。
