ror中关于中文的支持方法

在application控制器中加入如下代码

     # 将set_charset方法定义成一个过滤器
	     before_filter :set_charset   
     # 设置字符集
	     def set_charset 
		@headers["Content-Type"] = "text/html; charset=gb2312"
		@response.headers["Content-Type"] = "text/html; charset=gb2312"
		suppress(ActiveRecord::StatementInvalid) do 
			ActiveRecord::Base.connection.execute 'SET NAMES gb2312' 			    
		end
	     end

当我在application.rb中添加：

before_filter :set_charset
protected
def set_charset
  @headers['Content-Type'] = "text/html; charset=utf-8"
end

浏览页面的时候就出现该错误：

You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]=

E:/rails/demo/test/app/controllers/application_controller.rb:18:in `set_charset'

请问该如何解决该错误呢？

有没有方法让ruby自动生成时就是utf-8格式呢？
