久々に rails new するぞ

devcontainer で rails new してみるのがゴール

ディレクトリを作っていく

$ mkdir Rails
$ mkdir rails-playground
$ cd $_
$ ruby -v
$ rbenv local 3.4.0-preview1
$ git init
$ git st
$ git add -A
$ gc

v7.2.0.beta2 を使ってみる

 ❯ bundle init
Writing new Gemfile to /Users/noriyo_tcp/MyPlayground/til/Rails/rails-playground/Gemfile
$ vi Gemfile

# frozen_string_literal: true

source "https://rubygems.org"

gem "rails", github: "rails/rails", tag: "v7.2.0.beta2"

$ bundle config set path 'vendor/bundle'
$ bundle install
# すでにディレクトリは作ってあるので rails new . で良いのかあ
# この時点ではまだ bundle exec
$ bundle exec rails -h
$ bundle exec rails new . -a propshaft -c tailwind -d postgresql

なんか .gitignore とGemfileが衝突しちゃったな。とりあえず Y (overwrite)

pin とか言っている。あとは foreman も入ってくれるのか。便利

.devcontainer/Dockerfile はこんな感じ

# Make sure RUBY_VERSION matches the Ruby version in .ruby-version
ARG RUBY_VERSION=3.4.0.preview1
FROM ghcr.io/rails/devcontainer/images/ruby:$RUBY_VERSION

 ❯ bin/rails -h
Usage:
  bin/rails COMMAND [options]

You must specify a command. The most common commands are:

  generate     Generate new code (short-cut alias: "g")
  console      Start the Rails console (short-cut alias: "c")
  server       Start the Rails server (short-cut alias: "s")
  test         Run tests except system tests (short-cut alias: "t")
  test:system  Run system tests
  dbconsole    Start a console for the database specified in config/database.yml
               (short-cut alias: "db")
  plugin new   Create a new Rails railtie or engine

All commands can be run with -h (or --help) for more information.

In addition to those commands, there are:

Add ostruct to your Gemfile or gemspec.

ostruct が 3.5.0 でデフォルトではなくなるので Gemfile に追加するようにとの警告が出ている。とりあえず Gemfile に追加してインストール

devcontainer で Docker のパスが見つからない

https://github.com/microsoft/vscode-remote-release/issues/9105

VS Code settings Dev > Containers: Docker Path でパスを指定しておく

# これで表示されるパスを指定しておく
 ❯ which docker
 /Users/noriyo_tcp/.docker/bin/docker

ruby 3.4.0-preview1 を使っていたせいで devcontainer がこけてしまった

3.3.3 をインストールする

 ❯ rbenv install 3.3.3
 ❯ bundle install --redownload
Fetching gem metadata from https://rubygems.org/.........
Your bundle is locked to strscan (3.1.1) from rubygems repository https://rubygems.org/ or installed locally, but that version can no longer be
found in that source. That means the author of strscan (3.1.1) has removed it. You'll need to update your bundle to a version other than strscan
(3.1.1) that hasn't been removed in order to install.

# Gemfile を削除して bundle install --redownload 再度実行
rm Gemfile.lock

.devcontainer/devcontainer.json にて

なんかコンテナ立ち上げた後の bin/setup はあるが、コンテナ内で bundle install するような記述はない
ということは rails はローカルに入れておくということなのかなやっぱり

もう一度 devcontainer を開こうとするとこんなエラーが

Error response from daemon: No such image: ghcr.io/rails/devcontainer/images/ruby:3.4.0.preview1

image の指定を修正する

.devcontainer/Dockerfile

ここでまだ 3.4.0-preview1 のほうを見ていたので修正した root の Dockerfile も

ここまでやって Rebuild and reopen in container

    volumes:
      - type: bind
        source: /Users/noriyo_tcp/MyPlayground/til/Rails
        target: /workspaces
        bind:
          create_host_path: true

見てると redis, standalone-chromium, postgres などのイメージを構築している

コンテナの中でわざわざまた bundle install しているぞ？

# in container
bin/dev

立ち上がった！ localhost:3000 で確認できた

一旦 Docker Desktop でサクッと止めておいた

コンテナの中だけにしたい

見た感じコンテナ内で bundle install しているようだから、ホスト側に入れておく必要はないのでは？
Remote connection とコンテナ止めておく

# on Host
gem list --no-versions | grep "^[a-z]" | xargs gem uninstall -aIx
rbenv exec gem list #=> rails はない
❯ rails -h
rbenv: rails: command not found

The `rails' command exists in these Ruby versions:
  2.1.1
  2.2.3
  2.5.3
  2.7.2
  2.7.3
  3.0.0
  3.1.2
  3.2.0
  # 3.3.3 には rails はない

そしてまた reopen in container する。コンテナ内ではすでに rails やその他 gem を入れてあるのですんなり動く

container で使用する拡張機能を指定する

該当する extension をタブで開いてadd devcontainers.json を押せば良い

Remote 用の設定画面で Solargraph: Use Bundler をオンにしてみた

Rals Guides の Getting Started をやっていくぞ

link_to の第2引数はパスヘルパーを使用しなくても、リソースを渡せば良いのだな？
元々そうだったっけ？ https://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to

そうだったっぽい

Deleting and Article

今では data-turbo-method, data-turbo-confirm を使うのだなあ

あとは Basic authentication を残すのみ

status を enum にして inclusion validation 使いたいな
