Rails奮闘記 サーバ立ち上げまで

だいぶ期間が空いてしまったけど…早速使ってみる。

小遣い管理システム作るぞー。

（railsのmanページに乗ってたURL：http://guides.rubyonrails.org/getting_started.htmlを参照した）

まず、ブログ領域を作成。

$ rails new testmoney 
create  
create  README
create  Rakefile
create  config.ru
create  .gitignore
create  Gemfile
create  app
create  app/controllers/application_controller.rb
create  app/helpers/application_helper.rb
create  app/views/layouts/application.html.erb
create  app/mailers
create  app/models
create  config
create  config/routes.rb
create  config/application.rb
create  config/environment.rb
create  config/environments
create  config/environments/development.rb
create  config/environments/production.rb
create  config/environments/test.rb
create  config/initializers
create  config/initializers/backtrace_silencers.rb
create  config/initializers/inflections.rb
create  config/initializers/mime_types.rb
create  config/initializers/secret_token.rb
create  config/initializers/session_store.rb
create  config/locales
create  config/locales/en.yml
create  config/boot.rb
create  config/database.yml
create  db
create  db/seeds.rb
create  doc
create  doc/README_FOR_APP
create  lib
create  lib/tasks
create  lib/tasks/.gitkeep
create  log
create  log/server.log
create  log/production.log
create  log/development.log
create  log/test.log
create  public
create  public/404.html
create  public/422.html
create  public/500.html
create  public/favicon.ico
create  public/index.html
create  public/robots.txt
create  public/images
create  public/images/rails.png
create  public/stylesheets
create  public/stylesheets/.gitkeep
create  public/javascripts
create  public/javascripts/application.js
create  public/javascripts/controls.js
create  public/javascripts/dragdrop.js
create  public/javascripts/effects.js
create  public/javascripts/prototype.js
create  public/javascripts/rails.js
create  script
create  script/rails
create  test
create  test/performance/browsing_test.rb
create  test/test_helper.rb
create  test/fixtures
create  test/functional
create  test/integration
create  test/unit
create  tmp
create  tmp/sessions
create  tmp/sockets
create  tmp/cache
create  tmp/pids
create  vendor/plugins
create  vendor/plugins/.gitkeep

次はbundler(Gem 管理ツール)のセットアップ。

$ bundle install 
Fetching source index for http://rubygems.org/
Using rake (0.8.7) 
Using abstract (1.0.0) 
Using activesupport (3.0.1) 
Using builder (2.1.2) 
Using i18n (0.4.1) 
Using activemodel (3.0.1) 
Using erubis (2.6.6) 
Using rack (1.2.1) 
Using rack-mount (0.6.13) 
Using rack-test (0.5.6) 
Using tzinfo (0.3.23) 
Using actionpack (3.0.1) 
Using mime-types (1.16) 
Using polyglot (0.3.1) 
Using treetop (1.4.8) 
Using mail (2.2.7) 
Using actionmailer (3.0.1) 
Using arel (1.0.1) 
Using activerecord (3.0.1) 
Using activeresource (3.0.1) 
Using bundler (1.0.3) 
Using thor (0.14.3) 
Using railties (3.0.1) 
Using rails (3.0.1) 
Using sqlite3-ruby (1.3.1) 
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

次にrakeコマンドで、データベースを作成。

$ rake db:create                                       [~/testmoney]
(in /Users/***/testmoney)
/Library/Ruby/Gems/1.8/gems/bundler-1.0.3/lib/bundler/runtime.rb:132: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

これで準備完了！（さすがrails！！）

サーバを起動してみる。

$ rails server
/Library/Ruby/Gems/1.8/gems/railties-3.0.1/lib/rails/script_rails_loader.rb:11: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

無事にサーバが見れてよかったです。

次回は、いよいよチューニング！

# ここまでは、マニュアル通りだもんね…。

MacPortsも入れた

Rubyのインストールが怪しいと踏んで、MacPortsもインストールした。
まとめるほどではないけど、一応メモ。

1. 本家からイメージをダウンロード。（Installing Macportsから一つめの箇条書きにあるOS名を選択）
2. 展開してインストール。

これだけで、OK。

使う感じは、以下のとおり。

$ port
MacPorts 1.9.1
Entering interactive mode... ("help" for help, "quit" to quit)
[Users/****] > help
port
[-bcdfknopqRstuvy] [-D portdir] [-F cmdfile] action [privopts] [actionflags]
[[portname|pseudo-portname|port-url] [@version] [+-variant]... [option=value]...]...
Supported actions
------------------
activate, archive, archivefetch, build, cat, cd, checksum, clean, configure,
contents, deactivate, dependents, deps, destroot, dir, distcheck, distfiles,
dmg, dpkg, echo, ed, edit, exit, extract, fetch, file, gohome, help,
info, install, installed, lint, list, livecheck, load, location, log,
mdmg, mirror, mpkg, notes, outdated, patch, pkg, platform, portpkg,
provides, quit, rdependents, rdeps, rpm, search, select, selfupdate,
setrequested, srpm, submit, sync, test, trace, unarchive, uninstall,
unload, unsetrequested, upgrade, url, usage, variants, version, work

Pseudo-portnames
----------------
Pseudo-portnames are words that may be used in place of a portname, and
which expand to some set of ports. The common pseudo-portnames are:
all, current, active, inactive, installed, uninstalled, outdated, obsolete,
requested, unrequested and leaves.
These pseudo-portnames expand to the set of ports named.

Additional pseudo-portnames start with...
variants:, variant:, description:, depends:, depends_lib:, depends_run:,
depends_build:, depends_fetch:, depends_extract:, portdir:, homepage:, epoch:,
platforms:, platform:, name:, long_description:, maintainers:, maintainer:,
categories:, category:, version:, revision:, license:, depof:, rdepof:,
dependentof:, and rdependentof:.
These each select a set of ports based on a regex search of metadata
about the ports. In all such cases, a standard regex pattern following
the colon will be used to select the set of ports to which the
pseudo-portname expands.

Portnames that contain standard glob characters will be expanded to the
set of ports matching the glob pattern.
Port expressions
----------------
Portnames, port glob patterns, and pseudo-portnames may be logically
combined using expressions consisting of and, or, not, !, (, and ).
For more information
--------------------
See man pages: port(1), macports.conf(5), portfile(7), portgroup(7),
porthier(7), portstyle(7). Also, see http://www.macports.org.

んで、実際にRubyのインストールもしてみた。

待ち時間が長いよー…。

Railsに再挑戦（立ち上がり編）

仕事の関係でRubyに触れる機会が増えた。
しばらく使う羽目になりそうだったので、学生の頃に生半可に教わったRailsに再挑戦しようと思う。

Ruby on Railsとは（勉強的な意味で）

Railsは、一言で言えばWebアプリケーションのフレームワーク、だと考えている。（Wikipediaにまんま書いてあったｗ）

MVC(Model-View-Controller)アーキテクチャの考えを軸として設計されている。それぞれ、意味は以下のとおり。

• データや手続きを表現する要素
• モデルのデータを取り出し、ユーザに最適な形で表現する要素
• ユーザの入力に対して応答（処理）する要素

…調べだしたら色々書きたくなったけど、まとめるのが大変そうだから、勉強系は次回に持ち越しｗ

今日はインストールとセットアップまで！

Railsのインストール

まずはインストールとセットアップなんだけど、Snow LeopardにはRailsがインストール済みな状態みたい。

$ rails -v
Rails 2.3.5

念のため、Railsのアップデート。

（root権限で実行するように。ここだけに限らないけど。）

と、早速エラーがｗ

$ sudo gem update rails

（途中でSuccessfully installed rails-3.0.0って出てるから、エラーじゃないのかも…）

しかし、libが無いって何だろう…？

もしかしてRailsのインストールが怪しい？と思って、再インストールをしようとしたら、

$ sudo gem install rails

同じかよ！

ちょいと調べたら、Rubyのバージョン（今が1.8.7）が最新じゃないからかも…

アップデートしてみた。

libversionが定義されてないとか、怪しいエラーっぽいけど、これでもう一回トライ。

…変わりませんでした…。明日、再調査します。

こーやってハマることが何だか懐かしいｗ

ちなみに、このgemsってのがよく分かってなかったので調査（メモ程度だけど）。

（RubyGemsはRubyの標準パッケージ管理システムで、Railsをはじめとした色々なパッケージの管理を行うことが可能。）

Railsのセットアップ

じゃあ、実際にセットアップへ。

…といきたかったけど、セットアップする前に何を作るか決めないと。

ブログやら色々他の人がやってるけど。

せっかくなので、最近マイブームのお小遣い帳のネタで。

お小遣い帳管理サイトをつくろうと思います。

次回から頑張ろう。

（ちゃんと続けられるように…）
