我使用Ruby 1.9.2和Rails 3.0.5

我有以下错误:

不兼容的字符编码:ASCII-8BIT和UTF-8

它与我认为的数据库无关.

错误是在视图中惹恼这一行(只是一个div haml调用):

#content

全栈:

    ActionView::Template::Error (incompatible character encodings: ASCII-8BIT and UTF-8):
        21:                     -flash.each do |name, msg|
        22:                         =content_tag :div, msg, :id => "flash_#{name}"
        23:                         %div.clear                      
        24:                     #content                                        
        25:                         = yield
        26:             = render :partial => "layouts/grid_right" if render_grid_right?
        27:             = render :partial => "layouts/footer"

我的Ruby 1.9和Rails 2.3.4出现以下错误.当用户提交非ASCII标准字符时会发生这种情况.

我阅读了很多在线资源,但似乎没有一个解决方案有效.

我尝试过使用(作为一些资源建议)

string.force_encoding('utf-8') 

但它没有帮助.

任何想法如何解决这个问题？有没有办法在保存到数据库之前消除这些字符？或者,有没有办法让它们显示？
