遭遇した事象

Dependabot の自動生成 PR をマージし、Rails のバージョンを7.1系から7.2系に上げたところ、rails db:seed 実行時にエラーが出るようになってしまった。

実際のエラーメッセージは以下のとおり。

$ bundle exec rails db:seed
Running via Spring preloader in process 170
Clean database
rake aborted!
NoMethodError: undefined method `schema_migration' for #<ActiveRecord::ConnectionAdapters::Mysql2Adapter:0x000000000084d0 env_name="development" role=:writing> (NoMethodError)

エラーメッセージを読み解くと、どうも database_cleaner-active_record という Gem が schema_migration というメソッドに対応していないために発生したエラーらしい。

解決方法

ターミナルで以下のコマンドを実行して database_cleaner-active_record を最新バージョン（database_cleaner-active_record (2.2.0)）に変更したのち、再度 rails db:seed を実行すると問題なくseedデータを投入することができた。

bundle update database_cleaner-active_record
