Rails 4 から Rails 6 へ更新するためにやったこと
Gemfile
内のgem 'rails'
をgem 'rails', '~> 6.1'
へと書き換えた後にやってみたこと。
元々はRails4
でscaffold
して作ったささやかなものなので、大規模な移行には耐えられないと考えています。それでもやったこととして、ご参考になれば。
app:update
をしてみる
Rails 6へ更新後、素直に Railsのアップデート rails app:update
を実行して、一応比較をしながら結果的に全てをy
にしています。
ほぼ脳死状態。
ログ
`app:update`を実行した際のログです。

Web(アプリケーション)サーバを指定しないと起動しない
私の記憶が定かではないのですが、Rails 4のときは特段指定しなくとも適当にWebアプリケーションサーバが起動されていた気がします。なんとなくデフォルトでそのようになっていたのでしょうが、古すぎて記憶にありません。少なくとも、私のRailsアプリケーションは、今回の更新によって、Web(アプリケーション)サーバを指定しないことには起動しませんでした。
起動時のコマンドは、次のようにGemfile
へ利用するアプリケーションを追加して、起動時のコマンドに -u puma
を指定しました。特にこれだというのはなく、前もpuma
使ってた気がするな程度の選択です。ひとまず動けばいい。
gem 'puma'
bundle exec rails server -p $PORT -e $RAILS_ENV -u puma
地味にHeroku
上で動かしているアプリケーションだったので、Procfile
も次のようにしています。
web:bundle exec rails server -p $PORT -e $RAILS_ENV -u puma
config.file_watcher が悪さをして、Rails Serverが起動できない
本当か分からないのですが、development
の環境においてこの機能を使えるようにしていると、なぜか実行できません。
注釈することで、この状況を回避できるようになりました。
Cannot Load Such File -- Listen (LoadError)によってrails Sできない!
/config/environment/development.rb
この機能を注釈する
config.file_watcher = ActiveSupport::EventedFileUpdateChecker
config.file_watcher
が何をするのか、本家の内容をひも解いてみました。
config.reload_classes_only_on_change
がtrue
の場合に、ファイルシステム上のファイル更新検出に使われるクラスを指定します。デフォルトのRailsではActiveSupport::FileUpdateChecker
、およびActiveSupport::EventedFileUpdateChecker
(これはlistenに依存します)が指定されます。カスタムクラスはこのActiveSupport::FileUpdateChecker
APIに従わなければなりません。
(Rails アプリケーションを設定する - Railsガイド)
うーん。よく分からない。理由が分からないのでもやもやする。
StandardError: Directly inheriting from ActiveRecord::Migration is not supported. エラーが発生した時の対処
rails Dbmigrateをする際に発生したDirectly Inheriting From ActiveRecordMigration Is Not supported.の解決法
Rails 5.0, 6.0で書き方が変わってしまったため、対処が必要ということです。
class CreatePeople < ActiveRecord::Migration[6.0] # [6.0]を追加
def change
create_table :people do |t|
t.string :name
t.date :birth
t.string :home
t.float :height
t.string :office
t.timestamps null: false
end
end
end
マイグレーションファイルの日付見て気がついたんですけど、このソースコード6年前に作ったんですね。そりゃ何も覚えてないわ。
config/routes がきれいさっぱりなくなってた
Scaffoldで作成してたconfig/routes.rb
内がきれいさっぱり無くなっていました。
仕方がないので、次のようにresources
を追加して元に戻しました。
Rails.application.routes.draw do
resources :people
end
以上で、わが家のRails 4アプリケーションはひとまず動くようになりました。とさ。
