这显然是ActiveResource的一个已知问题：

https://github.com/rails/rails/issues/588

不幸的是，似乎没有任何关于它的事情。问题已经结束。如果您对此感到满意，那么用于更新ActiveResource和Hash.from_xml以保留所有属性的Rails 3代码都在下面的要点中，您可以在Redmine模块中创建一个定制版本来修复它：

<强>更新

另一种选择，因为它显示ActiveResource will not be part of Rails 4 core并将作为单独的gem分离出来，将使用替代ORM for REST API，如Her。

她允许您为XML使用自定义解析器。这是一个名为Redmine :: ParseXML的示例自定义解析器：

https://gist.github.com/3879418

那么你需要做的就是创建一个像config / initializers / her.rb这样的文件：

Her::API.setup :url => "https://api.xxxxx.org" do |connection|
  connection.use Faraday::Request::UrlEncoded
  connection.use Redmine::ParseXML
  connection.use Faraday::Adapter::NetHttp
end

你会得到如下的哈希：
