NullDB not configured. Require a framework, ex 'nulldb/rails'

Github CI/CD Docker Rails

huh?

なにこれ

GithubActions で Docker ビルドする際、表題の通り assets:precompile でコケるようになった。 ので、ローカルで再現を試みた。

❯ RAILS_ENV=production DATABASE_ADAPTER=nulldb SECRET_KEY_BASE=dummy bundle exec rails assets:precompile

えー？

NullDB not configured. Require a framework, ex 'nulldb/rails'

どうも NullDB が存在しないらしい。

Gemfile.lock にはちゃんと存在している。

    activerecord-nulldb-adapter (0.9.0)
      activerecord (>= 5.2.0, < 7.1)

雑に解決する

とりあえず require すれば解決するので application.rb に雑に書いてしまう。

# frozen_string_literal: true

require_relative 'boot'

require 'rails'
# Pick the frameworks you want:

... snip ...

require 'nulldb/rails' # このように雑に追加しておく

Bundler.require(*Rails.groups)

module App
  class Application < Rails::Application

... snip ...

再度 assets:precompile を流す

❯ RAILS_ENV=production DATABASE_ADAPTER=nulldb SECRET_KEY_BASE=dummy bundle exec rails assets:precompile

やったぜ。

原因？

どこかで暗黙的に require していた？ とも考えたのだけど、該当の build がコケはじめた前後でプロジェクト全体を確認しても、 require を変更した部分が見つからなかったので、本当に謎。

このタイミングで バージョンが 0.9.0 -> 1.0.1 に上がっていたのでその関係かな、と思っていたが、 Changelog を見る限りなにか破壊的な変更が行われたわけではなさそう。

github.com

実際、前述の通り application.rb へ明示的に require 書いたら 0.9.0 でも 1.0.1 でも DATABASE_ADAPTER=nulldb 指定でちゃんと動いたので……。

いかがだったでしょうか

いかがもクソもないんじゃ、という感じですが。

実は対応したこのプロジェクト、コーディングではなくインフラの担当なので、結合で出た不具合への対応って感じで、うーん……という気持ちになっている。 雑に、と本文中に書いたのはそういうトコがあったのでした。

最近こういう責務を超えた対応、全部投げられてしまう傾向にあってかなりだいぶ辛い。 (担当のチームにリプライ送っても「そちらで対応してください (知らんわからん！)」と言われてしまうのだった。
