Rails 3.1,Ruby 1.9.2-p180和UTF-8问题

Question

我在使用UTF-8字符时遇到了一些麻烦.这是db/seeds.rb

User.create(username: 'eml', first_name: '****', last_name: '****äck', 
            email: 'somemail@example.com', password: 'asdasd')

我的终端(OSX 10.5.8)设置为使用UTF-8,Rails(根据application.rb)设置为使用utf-8.这是错误:

$ rake db:seed
rake aborted!
/Projects/***/db/seeds.rb:8: invalid multibyte char (US-ASCII)
/Projects/***/db/seeds.rb:8: invalid multibyte char (US-ASCII)
/Projects/***/db/seeds.rb:8: syntax error, unexpected $end, expecting ')'
...ame: '****', last_name: '****äck', 
...                               ^

Tasks: TOP => db:seed
(See full trace by running task with --trace)

Answer 1

# encoding: utf-8在seeds.rb文件顶部添加此行,任何ruby文件都使用spécialschars

我建议你添加Encoding.default_external = "UTF-8"到config.ru文件和config/environment.rb编码模板

最后,你可以添加"".force_encoding('UTF-8)到你的字符串,造成问题.

更新:

在config.ru上添加完整行:

# Not override -E option or LANG and apply only for ruby > 1.9
if Object.const_defined?(:Encoding) && !ENV['LANG'] && !ENV['RUBYOPT'].include?('-E')
Encoding.default_internal = 'utf-8'
Encoding.default_external = 'utf-8'
end
