Rails6の初期設定をする〜PostgreSQL, Tailwind CSS〜

9 min read

環境

開発環境はMacです。
基本的にbrewで環境整えました。

バージョン
Ruby 2.7.2
Rails 6.1.3
PostgreSQL 12.6

手順

アプリを作成

$ rails new appname -M -d postgresql
  1. rails new appnameでアプリ名「appname」を指定
  2. -MでAction Mailerを組み込まないようにする
  3. -d postgresqlで使用するDBサーバー に「PostgreSQL」を指定

参考

不要なroutesを削除(Action Mailbox)

作成したアプリのroutesを確認すると、すでにいろいろなroutesが設定されています。
今回のアプリで使用しない設定は削除します。

routesのパスを見たところ、Active MailboxActive Storageの設定が入っているようです。
今回はAction Mailのみ削除します。
Active Storageは実際に作成しているアプリはGoogle Cloud Storageを使用する予定なので残しておきます

設定を削除

config/application.rb
require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "active_storage/engine"
require "action_controller/railtie"
# require "action_mailer/railtie" 
# ↓Action Mailboxの設定をコメントアウト↓ 
# require "action_mailbox/engine"
require "action_text/engine"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie"
require "rails/test_unit/railtie"

routesの確認

補足
ちなみにActive Storageの設定削除はrails newオプションでできるそうです

PostgreSQLの接続設定

PostgreSQLのインストール
config/detabase.ymlの設定をしてください。

Tailwind CSSの設定

Tailwind CSSのgemを追加

Gemfileに追記

Gemfile
gem 'tailwindcss-rails'

インストール

$ bin/bundle install
$ bin/rails tailwindcss:install

参考
