作業メモ: Mastodon upgrade v2.4.3 → v2.4.4

v2.4.4 にアップグレードしようとしたら db:migrate でコケた。

$ docker-compose run --rm web rails db:migrate

custom_filters テーブルが既に存在しているのに作ろうとしているらしい。中身空っぽだし、dropしてええやろ、ということで以下の修正を入れた。

$ vim db/migrate/20180628181026_create_custom_filters.rb
$ git diff
diff --git a/db/migrate/20180628181026_create_custom_filters.rb b/db/migrate/20180628181026_create_custom_filters.rb

改めて実行したら成功したので、migrationファイルを元に戻しておく。

$ git checkout db/migrate/20180628181026_create_custom_filters.rb

assets:precompileは問題なし。

$ docker-compose run --rm web rails assets:precompile
