为什么我升级到 Rails 3 后所有字符串都是 ASCII-8BIT? [英] Why are all strings ASCII-8BIT after I upgraded to Rails 3?

问题描述

我升级到 RoR 3.0.1，Ruby 升级到 1.9.2.现在我视图中的所有字符串都是 ASCII-8BIT?

I upgraded to RoR 3.0.1 and Ruby to 1.9.2. Now all the strings in my views are ASCII-8BIT?

我相信我的应用已设置为使用 UTF 8

I believe I have my app set up to use UTF 8

application.rb

config.encoding = "utf-8"

database.yml

development:
  adapter: mysql
  encoding: utf8

我在跑步

OS X
RVM rvm 1.0.16 
Ruby ruby-1.9.2-p0
Rails 3.0.1

我希望编码是 UTF 8 而不是 ASCII

business.desc.encoding
# ASCII-8BIT

由于 1.9.x 可以连接不同编码的字符串，我们看到很多这样的错误.

Since 1.9.x can concatenate strings of different encodings we see a lot of errors like this.

<p class="description"><%= truncate(business.desc, :length => 17) %></p>

错误

incompatible character encodings: ASCII-8BIT and UTF-8

activesupport (3.0.1) lib/active_support/core_ext/string/output_safety.rb:74:in `concat'

其他人有这个问题吗?ruby-1.9.2-p0 是要使用的正确版本吗?

Does anyone else have this problem? Is ruby-1.9.2-p0 the correct version to use?

谢谢！

推荐答案

您需要将此添加到每个 .rb 文件中:

You need to add this to every .rb file:

<% # coding: UTF-8 %>

为此我使用 gem magic_encoding.

I use the gem magic_encoding for that.

$ cd app/ 
$ magic_encoding

默认为 UTF-8，但您可以指定任何您想要的参数作为参数.

The default is UTF-8, but you can specify whatever you want as an argument.
