親テーブルと子テーブルのIDを比較する 不整合があればテーブルを修正する

外部キー制約を追加するmigration ファイルをつくる

% rails generate migration AddOtherReferenceToJournal other:references
invoke active_record
create db/migrate/20230509044353_add_other_reference_to_journal.rb</nowiki>
rails db:migrateでエラー
すでにother_idカラムが存在するのでadd_referenceメソッドが実行できない
直接データベースを操作してother_idカラム名をhoge_idカラム名に変更する
ALTER TABLE journals RENAME COLUMN other_id TO hoge_id;
rails db:migrate
hoge_idカラムの値をother_idカラムにコピーする
UPDATE journals SET other_id = hoge_id;
ローカルならrails consoleを使用して
Journal.update_all('other_id = hoge_id')
hoge_idを削除する
ALTER TABLE journals DROP COLUMN hoge_id;
=== エラー ===
例えば待避したhoge_idを戻すとき次のようなエラーがでる
<nowiki>=# UPDATE journals SET schedule_id = hoge_id;
ERROR: insert or update on table "journals" violates foreign key constraint "fk_rails_9d4d4268db"
DETAIL: Key (schedule_id)=(970) is not present in table "schedules".</nowiki>
journalsテーブルのschedule_idがschedulesテーブルにないのでそれを拾い出して削除する
<nowiki>=# delete from journals where hoge_id in (
SELECT id FROM schedules
EXCEPT
SELECT hoge_id FROM journals
UNION ALL
SELECT hoge_id FROM journals
EXCEPT
SELECT id FROM schedules);</nowiki>
