エラー内容

「フロントエンド開発のためのテスト入門」 10章で開発環境構築をしていたら以下のエラーが生じた

$ npm run prisma:migrate 

> frontend-testing-book-nextjs@1.0.0 prisma:migrate
> prisma migrate dev

Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma
Datasource "db": PostgreSQL database "app-db", schema "public" at "localhost:5432"

Error: P1010: User `root` was denied access on the database `app-db.public`

rootでアクセスできないというその通りのエラーだが、本の通りにはやっていたので記録として残す

エラー解消方法

// 実際にDockerでたてているpostgrespostgresユーザでログインする
$ psql -h localhost -p 5432 -U postgres

// postgres内でroleを確認すると、rootがない
postgres-# \du
                                     List of roles
  Role name   |                         Attributes                         | Member of
--------------+------------------------------------------------------------+-----------
 osaosa       | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
 postgres     | Superuser                                                  | {}

// rootユーザを以下のコマンドで作成
postgres=# create role root with superuser login password 'password';

// rootユーザが作成されていることを確認
postgres=# \du
                                     List of roles
  Role name   |                         Attributes                         | Member of
--------------+------------------------------------------------------------+-----------
 osaosa       | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
 postgres     | Superuser                                                  | {}
 root         | Superuser                                                  | {}

マイグレーションできるのを確認

$ npm run prisma:migrate 

> frontend-testing-book-nextjs@1.0.0 prisma:migrate
> prisma migrate dev

Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma
Datasource "db": PostgreSQL database "app-db", schema "public" at "localhost:5432"
