Ruby On Rails开发环境For Windows(更新)

　　一、Windows下rails环境安装
　　很简单一步搞定。。。
　　1.下载Rails DevKit：railsinstaller-version.exe 下载地址 http://railsinstaller.org/ 
　　railsinstaller-2.1.exe下载地址http://download.csdn.net/download/loveanna7/5147502
　　2.安装rails：执行railsinstaller-version.exe安装rails。傻瓜式安装（有一点要注意，安装路径不要有空格）；其他组件也一并会安装上，包括ruby、gem、bundle等。
　　3.安装完成后点完成的时候，那个界面的复选框选上的话，我们就要进入git设置。会自动打开终端，只要输入姓名和邮箱会自动配置好。
　　4.配置完成之后终端会自动进入C:\Sites。我们现在可以查看我们安装的环境的版本号:ruby -v;rails -v;gem -v;bundle -v

　　二、新建应用程序
　　1.创建一个demo应用程序：cd到工作目录，如：E:\works\ruby，执行rails new demo，会创建一个名为demo的应用程序
　　2.cd到demo目录
　　3.启动自带默认的rails服务器：rails server
　　4.浏览器打开http://localhost:3000

　　三、Hello Rails 
　　写一个hello world程序试试手，新打开一个终端，并cd到E:\works\ruby\demo
　　1.用rails生成一个名为say的控制器，用命令：rails generate controller Say hello goodbye
　　日志信息：

E:\works\ruby\demo>rails generate controller Say hello goodbye

　　2.控制器demo/app/controllers/say_controller.rb代码

class SayController < ApplicationController
def hello
end
def goodbye
end
end
　　
　　可以看到是继承了ApplicationController类，里面有两个空的方法。
　　3.rails的url请求，浏览器访问：http://localhost:3000/say/hello

　　我们运行rails generate时生成了6个文件1个目录say，这个目录用来存放控制器视图的模板文件，我们创建了say控制器，视图就位于app/views/say中。
　　默认rails会寻找与当前动力(action)同名的文件中的模板。这里我们修改app/views/say/hello.html.erb模板文件，只要在其中添加HTML代码。
　　当前代码

<h1>Say#hello</h1>
<p>Find me in app/views/say/hello.html.erb</p>
　　
　　修改之后：

<h1>Hello from Rails</h1>
　　
　　刷新浏览器可看到：

　　4.在模板中添加动态内容：每次显示页面时也显示当前时间。
　　模板文件用.html.erb后缀，是告诉rails，需要借助ERb系统对文件的内容进行扩展，就像jsp/asp/php一样的动态页面文件。ERb是一个过滤器，包含在rails的默认安装里。
　　修改app/views/say/hello.html.erb模板，添加显示当前时间：

<h1>Hello from Rails</h1>
<p>
It is new <%= Time.now %>
</p>
　　
　　刷新浏览器：

　　5.将“获取时间”的方法写在控制器中，视图则只承担显示信息的职责。
　　对控制器中hello方法进行修改，将时间值放在@time的实例变量中，.html.erb模板中输出实例变量即可。
　　修改控制器app/controllers/say_controller.rb：

class SayController < ApplicationController
def hello
@time = Time.now
end
def goodbye
end
end
　　
　　修改app/views/say/hello.html.erb模板:

<h1>Hello from Rails</h1>
<p>
It is new <%= @time %>
</p>
　　
　　刷新浏览器， 只看到时间更新。
　　
　　四、把页面连起来
　　1.创建应用的时候，还创建一个goodbye的动作，对应的模板app/views/say/goodbye.html.erb，现在用得上了，修改它：

<h1>Goodbye!</h1>
<p>
It was nice having you here.
</p>
　　
　　2.打开http://localhost:3000/say/goodbye

　　3.把hello和goodbye页面连接起来：现在需要在两个模板页面上添加链接，让其互相跳转。
　　hello.html.erb添加:

<p>
Say <a href="/say/hello">Hello</a>!
</p>
　　
　　goodbye.html.erb添加:

<p>
Say <a href="/say/goodbye">Goodbye</a>!
</p>
　　


　　4.现在这样是管用，但是如果把应用程序移到Web服务器的另一个目录下，这些Url就会失效。实际上我们可以使用Rails提供的视图模板中的辅助方法。现在使用辅助方法添加跳转链接。
　　修改hello.html.erb:

<h1>Hello from Rails</h1>
<p>
It is new <%= @time %>
</p>
<p>
Time to say
<%= link_to "Goodbye", say_goodbye_path %>!
</p>
　　
　　修改goodbye.html.erb:

<h1>Goodbye!</h1>
<p>
It was nice having you here.
</p>
<p>
Say <%= link_to "Hello", say_hello_path %> again.
</p>
　　
　　link_to()是一个方法（在rails中把这样的方法叫做辅助方法(helper)，因为它给编写视图模板带来了便利）。这里使用时省略了圆括号。
　　say_goodbye_path参数是rails预计算过的一个值。
