如果解决乱码问题显示出错

关于中文显示乱码的问题,以前都是这么修改

before_filter :set_charset     
def set_charset      
   if request.xhr?      
     @headers['Content-Type']="text/javascript,charset=utf-8"     
   else     
     @headers['Content-Type']="text/html,charset=utf-8"     
   end     
   suppress(ActiveRecord::StatementInvalid) do  
   ActiveRecord::Base.connection.execute 'SET NAMES UTF8'  
   end  
end 

但是,你升级完Rails2.3
可能会出现错误提示:

或者


Example of what we used to do:

response.headers["Content-Type"] = "application/atom+xml; charset=utf-8" 

得改成如下:

response.content_type = Mime::ATOM 
response.charset = "utf-8" 

就是说改成这样在Rails2.3是能用的

before_filter :set_charset     
def set_charset      
  response.content_type = Mime::ATOM 
  response.charset = "utf-8"
end
 

@title = "中文"
中文字符串的乱码怎么解决呢？
