どうもてぃ。
久々にローカルDB環境を作ってて１０分ほどハマったので、二度とないように備忘録書いときます。
環境
% cat /etc/lsb-release DISTRIB_ID=LinuxMint DISTRIB_RELEASE=19.3 DISTRIB_CODENAME=tricia DISTRIB_DESCRIPTION="Linux Mint 19.3 Tricia"
database.ymlの設定
config/database.ymlはこんな感じ。
default: &default
adapter: postgresql
encoding: unicode
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: <%= ENV['POSTGRES_DB'] %>
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: <%= ENV['POSTGRES_DB_TEST'] %>
usernameやpasswordは面倒くさかったので設定してません。
Let's rails db:create
% bundle exec rails db:create % bundle exec rails db:create FATAL: role "motty" does not exist Couldn't create 'project_dev' database. Please check your configuration. rails aborted! ActiveRecord::NoDatabaseError: FATAL: role "motty" does not exist

postgresqlをインストールした後なにもしてなかったので、ロールがないって怒られちゃいました。
roleを作成する
まずはポスグレの中に入ります
% sudo -u postgres psql psql (10.14 (Ubuntu 10.14-0ubuntu0.18.04.1)) Type "help" for help. postgres=#
ロールの確認をすると
postgres=# \du List of roles Role name | Attributes | Member of -----------+------------------------------------------------------------+----------- postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
mottyっていうロールないですね（そりゃそうだわ）
てなわけで作りま。
postgres=# create role motty login createdb createrole password 'password'; CREATE ROLE postgres=# \du List of roles Role name | Attributes | Member of -----------+------------------------------------------------------------+----------- motty | Create role, Create DB | {} postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
完璧にロールmottyが作成できました。
\qで戻れます。
おわり
rails db:createも無事に通りました。
普段自分が作ったdocker templateを使用してるので、まさかこんなところでハマるとは思ってませんでした。
もう二度とローカル環境構築とかいう無駄なことはやりたくないなぁ、と思う今日この頃でした。
おしまい。
