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>
