今天看了一下語言排行,看到ruby 下來玩了一下,就此記錄一下如何配置.

1.先要下載ruby安裝 ,http://www.ruby-lang.org

2.當然是安裝rails 了, 打命令行下行打 c:/>gem install rails 自動會遠程下載安裝.

3.新建項目吧 rails mybook,會產生一堆東東.

4.配置數據庫

development:
   adapter: mysql
   database: mybook
   host: localhost
   username: root
   password: 123456

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
   adapter: mysql
   database: mybook
   host: localhost
   username: root
   password: 123456

production:
   adapter: mysql
   database: mybook
   host: localhost
   username: root
   password: 123456

就此說明一點 :後邊一定要空格的, 這個要注意喔,還有就是產生控制器,沒有配數據庫的話,老是不執行

控制器裡的動作.搞不明白,

5.新建控制器 ruby generate controller book,會在controller目錄產生book_controller.rb 這個

6.在book_controller.rb中創建一個方法 index

7.在view/book 下新建index.rhtml

index.rhtml:

<html>
<head>
<title>Rails</title>
</head>
<body>
<H1>Hello Rails </H1>
</body>
</html>

8.啟動服務器 ruby server

9. http://127.0.0.1:3000/book/
