rails中修改页面和应用的字符集

整个应用中字符集换为gbk：1 打开Rails目录中的.app/controllers/application.rb2 增加过滤器代码before_filter :set_charsetdef set_charset@headers["Content-Type"] = "text/html; charset=gbk"end单个页面增加<%@headers["Content-Type"] = "text/html; charset=gbk"%>即可Ruby on rails

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？
