ruby-on-rails-3 - Rails 3.0.3：使用带有 globalize3 的vestal_versions

Question

我正在尝试将vestal_versions (1.2.2) 添加到使用globalize3 (0.0.11) 进行模型本地化的站点。

当我尝试像这样显示模型的版本时：

 <% if can?(:edit, Page) then %>
  <div class="edit_link"><%= link_to image_tag("appicons/edit.png", :alt => t(:edit)), edit_page_path(@page) %><br />
  Version <%= @page.version %></div>
<% end %>

我得到：

查看器中的类型错误#show

显示 /home/florian/spzwww3/app/views/viewer/show.html.erb 其中第 50 行提出：

无法访问条件

第 50 行是与@page.version

在控制台中显示版本工作正常：

ruby-1.9.2-p0 > p = Page.find(:last)
ruby-1.9.2-p0 > p.version
 => 1 

任何想法“无法访问条件”条件意味着什么？

我以前从未见过这条消息，谷歌只返回一个与该短语无关的结果。

提前感谢您的任何提示。
