第一個(gè)網(wǎng)站

使用SQLite3測(cè)試：

#### If you want to use SQLite (not recommended)

rails new myapp

#### If you want to use MySQL

rails new myapp -d mysql

#### If you want to use Postgres

# Note that this will expect a postgres user with the same username

# as your app, you may need to edit config/database.yml to match the

# user you created earlier

rails new myapp -d postgresql

# Move into the application directory

cd myapp

# If you setup MySQL or Postgres with a username/password, modify the

# config/database.yml file to contain the username/password that you specified

# Create the database

rake db:create

rails server

打開(kāi) http://localhost:3000 即看到封面。

第一個(gè)CRUD功能

rails generate scaffold Person first_name:string last_name:string phone_number:string address:text

rake db:migrate

rake db:migrate RAILS_ENV=production

現(xiàn)在打開(kāi) http://localhost:3000/people 即有一個(gè)人員管理CRUD頁(yè)面。
