rails 5.1.6 のアプリをrails 5.2.0にアップデートしたときに、いろいろハマったのでメモ。

rails側

rails側での作業メモ。

cannot load such file -- bootsnap/setup

とりあえず rails app:updateしてみる。 route.rbなどは上書きしたらダメだけど、boot.rbとか触った覚えのないファイルは上書きしていく。

$ rails app:update
conflict  config/boot.rb
Overwrite /Users/tkmru/code/old_app/config/boot.rb? (enter "h" for help) [Ynaqdh] Y
       force  config/boot.rb
       exist  config
    conflict  config/routes.rb
Overwrite /Users/tkmru/code/old_app/config/routes.rb? (enter "h" for help) [Ynaqdh] n
...

rails serverを起動するとbootsnapというrailsの起動を早くするgemがないとエラーが出た。railsが標準で使うようになったとのこと。

週刊Railsウォッチ（20170728）bootsnapがRailsで正式採用、Ruby Prizeの推薦開始、PostgreSQL配列の重複を除去ほか

gemファイルに追加してbundle installする。

$ bin/rails s

undefined method `halt_callback_chains_on_return_false=' for ActiveSupport:Module

halt_callback_chains_on_return_falseはRails 4との後方互換のためのメソッドで、rails serverを起動するとこれがないというエラーが出た。

Ruby on Rails 5.2.0 Deprecations – Drifting Rubyによると、 5.2よりhalt_callback_chains_on_return_falseは削除されたみたい。 config/initializers/new_framework_defaults.rbの中のhalt_callback_chains_on_return_falseの行をコメントアウトした。

# Be sure to restart your server when you modify this file.
#
# This file contains migration options to ease your Rails 5.0 upgrade.
#
# Read the Guide for Upgrading Ruby on Rails for more info on each option.

Rails.application.config.raise_on_unfiltered_parameters = true

# Enable per-form CSRF tokens. Previous versions had false.
Rails.application.config.action_controller.per_form_csrf_tokens = true

# Enable origin-checking CSRF mitigation. Previous versions had false.
Rails.application.config.action_controller.forgery_protection_origin_check = true

# Make Ruby 2.4 preserve the timezone of the receiver when calling `to_time`.
# Previous versions had false.
ActiveSupport.to_time_preserves_timezone = true

# Require `belongs_to` associations by default. Previous versions had false.
Rails.application.config.active_record.belongs_to_required_by_default = true

# Do not halt callback chains when a callback returns false. Previous versions had true.
# ActiveSupport.halt_callback_chains_on_return_false = false # これをコメントアウトした！！

# Configure SSL options to enable HSTS with subdomains. Previous versions had false.
Rails.application.config.ssl_options = { hsts: { subdomains: true } }

これでrailsは起動するようになった。

フロントエンド側の作業メモ

can't find executable webpack for gem webpacker

webpackを実行してみると、gemのwebpackerから動かせるwebpackがないってエラーが出た。

$ bin/webpack
Traceback (most recent call last):
    2: from bin/webpack:17:in `<main>'
    1: from /Users/tkmru/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/bundler-1.16.1/lib/bundler/rubygems_integration.rb:489:in `block in replace_bin_path'

rails webpacker:binstubsでwebpackのバイナリを再インストールすると、webpackも動くようになった。
