不兼容的字符编码:ASCII-8BIT和UTF-8
问题描述：
我使用Ruby 1.9.2和Rails 3.0.5
I use Ruby 1.9.2 and Rails 3.0.5
我遇到以下错误:
不兼容的字符编码:ASCII-8BIT和UTF-8
incompatible character encodings: ASCII-8BIT and UTF-8
我认为它与数据库无关.
It has nothing to do with the database i think.
错误在于视图中的这一行(只是一个div haml调用):
The error is happinging on this line in a view (just a div haml call):
#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?

答
我怀疑您是将Haml模板的一部分复制/粘贴到了文件中，还是正在使用非Unicode/非UTF-8友好的编辑器.
I have a suspicion that you either copy/pasted a part of your Haml template into the file, or you're working with a non-Unicode/non-UTF-8 friendly editor.
查看是否可以在UTF-8友好编辑器中从头开始重新创建该文件.任何平台都有很多东西，看看是否可以解决您的问题.首先用#content擦除该行，然后手动重新键入.
See if you can recreate that file from the scratch in a UTF-8 friendly editor. There are plenty for any platform and see whether this fixes your problem. Start by erasing the line with #content and retyping it manually.
