有机会再试一试rails了,只是原来接触的是2,现在已然变成了4,似乎现在的安装比原来会快些。。

有机会再试一试rails了,只是原来接触的是2,现在已然变成了4,似乎现在的安装比原来会快些。。
rails 4 安装
针对于安装了rvm
复制代码 代码如下:
gem install rails
没有的话应该这样:
复制代码 代码如下:
sudo gem install rails
安装rvm可以用句
复制代码 代码如下:
curl -l https://get.rvm.io | bash -s stable
查看rails版本
复制代码 代码如下:
rails -v
rails 4.0.3
rails 4.0.3
似乎这就是当前的最新版本
ruby版本
复制代码 代码如下:
we recommend ruby 2.1.0 for use with rails. we stopped supporting ruby 1.8.x after rails 3.2. ruby 1.9.2+ will be supported until rails 5.
官方推荐用2.1.0. 也就是最新版本
安装sqlite
似乎这就是诸如django、rails这类对于轻量级网站的数据库要求。
如果是mac os
复制代码 代码如下:
brew install sqlite3
其他可以看情况安装,如opensuse
复制代码 代码如下:
sudo zypper install sqlite3
rails 4 hello,world
可以直接用rails生成
复制代码 代码如下:
$rails new hello
于是就有了

create config.ru
create .gitignore

接着会安装包依赖
复制代码 代码如下:

your bundle is complete!
use `bundle show [gemname]` to see where a bundled gem is installed.
运行rails
复制代码 代码如下:
$rails server
这样的话打开 http://localhost:3000 就可以看到,rails的欢迎界面welcome aboard,有点类似于django-cms的小马哥~~
创建controller
如官方指南所说http://guides.rubyonrails.org/getting_started.html
执行命令:
复制代码 代码如下:
$rails generate controller welcome index
就会创建下面这些文件:
复制代码 代码如下:
create app/controllers/welcome_controller.rb
route get "welcome/index"
invoke erb
create app/views/welcome
create app/views/welcome/index.html.erb
invoke test_unit
create test/controllers/welcome_controller_test.rb
invoke helper
create app/helpers/welcome_helper.rb
invoke test_unit
create test/helpers/welcome_helper_test.rb
invoke assets
invoke coffee
create app/assets/javascripts/welcome.js.coffee
invoke scss
create app/assets/stylesheets/welcome.css.scss
在config/routes.rb添加默认页面
复制代码 代码如下:
root 'welcome#index'
再运行
复制代码 代码如下:
rails server
就会出现
复制代码 代码如下:
welcome#index
find me in app/views/welcome/index.html.erb
一切来得很快,很突然。
