覚えたことを復唱してみる。 だって、忘れっぽいんですもの。

Rails4 HelloWorld

http://guides.rubyonrails.org/getting_started.htmlを見ながらRails4でHelloWorldやってみました。

```$ rails new blog $ cd blog $ vi Gemfile(追記) gem ‘execjs’ gem ‘therubyracer’ $ rails server


```$ rails generate controller welcome index
$ vi app/views/welcom/index.html.erb
(全部消して、したのを書く)
<h1>Hello, Rails!</h1>

アプリケーションのホームページにする config/routes.rbを編集する

Blog::Application.routes.draw do
get “welcome/index”
# The priority is based upon order of creation:

# first created -> highest priority.
# …
# You can have the root of your site routed with “root”
# root to: “welcome#index”

これを

Blog::Application.routes.draw do
get “welcome/index”
# The priority is based upon order of creation:

# first created -> highest priority.
# …
# You can have the root of your site routed with “root”
root to: “welcome#index”　　⬅コメントはずした

これでhttp://localhost:3000/welcome/index これでも、

http://localhost:3000/これでもアクセスできます。

もう一回、AWSにRails4とか

AWSにrails4とか – rails4起動 

rails new railstest –edge
cd railstest
bundle install
bundle exec rails server

下のメッセージが出たら成功

AWSにrails4とか – rvm

rvmインストール 当たり前ですが、rubyのインストールは時間がかかります。

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer" target="_blank">https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

source /etc/profile.d/rvm.sh
rvm get latest
rvm list known
rvm install 1.9.3
rvm install 2.0.0
rvm list 
rvm –default 1.9.3
rvm use 2.0.0
