railsでscaffoldを使う(簡易手順)

More than 1 year has passed since last update.

はじめに

Ruby on RailsでHelloWorldプロジェクト でScaffoldを使わずにプロジェクト作成をした。
Scaffoldってどうなんだろうと思い、使ってみました。

サクッと作れたので簡単にまとめてみました。
これだけのコマンドでWebアプリが作れてしまうのは凄いですね…。

作成〜起動

> bundle init
(Gemfile修正)
> bundle install --path vendor/bundle
> bundle exec rails new . -B -d mysql
> Y
> bundle install --path vendor/bundle
(database.yml修正)
> bundle exec rake db:create
> bundle exec rails generate scaffold ScaffoldMessage name:string mail:string title:string message:string
> bundle exec rake db:migrate
> bundle exec rails server

scaffoldで作成したファイルを全削除する場合

> bundle exec rails destroy scaffold ScaffoldMessage
