升级到Rails 3后,为什么所有字符串都是ASCII-8BIT？

Question

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

我相信我的应用程序设置为使用UTF 8

application.rb中

config.encoding = "utf-8"

database.yml的

development:
  adapter: mysql
  encoding: utf8

我在跑

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,我们会看到很多这样的错误.

<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'

还有其他人有这个问题吗？ruby-1.9.2-p0是否使用正确的版本？

谢谢!

Answer 1

可怕的问题.您需要将它放在每个文件的顶部

# coding: UTF-8

更新使用如Nerian所述的magic_encoding.

与下面的内容基本相同,但更好.

/ UPDATE

我有一个rake任务,我不记得我找到了什么(对那个人的称赞!)我稍微修改了一下,把它放在每个文件的顶部.我听说有人说上面(你做过的)应该足够了,但它对我不起作用......

无论如何,这是rake任务,只需复制粘贴即可

lib/tasks/utf8encode.rake

# coding: UTF-8

desc "Manage the encoding header of Ruby files"
task :utf8_encode_headers => :environment do
  files = Array.new
  ["*.rb", "*.rake"].each do |extension|
    files.concat(Dir[ File.join(Dir.getwd.split(/\\/), "**", extension) ])
  end

  files.each do |file|
    content = File.read(file)
    next if content[0..16] == "# coding: UTF-8\n\n" ||
            content[0..22] == "# -*- coding: utf-8 -*-"

   ["\n\n", "\n"].each do |file_end|
      content = content.gsub(/(# encoding: UTF-8#{file_end})|(# coding: UTF-8#{file_end})|(# -*- coding: UTF-8 -*-#{file_end})|(# -*- coding: utf-8 -*-#{file_end})/i, "")
    end

    new_file = File.open(file, "w")
    new_file.write("# coding: UTF-8\n\n"+content)
    new_file.close
  end
end

Answer 2

您需要将其添加到每个 .rb 文件中：

<% # coding: UTF-8 %>

我为此使用 gem magic_encoding 。

$ cd app/ 
$ magic_encoding

默认值为 UTF-8，但您可以指定任何您想要的参数作为参数。
