生产中的 Haml 渲染错误

Question

我正在 Mac OSX 上编写一个 Rails 3 应用程序，它在开发和生产环境下都运行良好。当我使用 Passenger 部署应用程序时，我的某个视图中出现错误。这就是视图的样子：

%p#refresh= link_to 'Refresh', '#', id: "refreshAreaLink"

#newAreaParagraph
  = link_to 'New area', '#', id: "createNewAreaLink"

- for area_group in AreaGroup.all
  .areaGroup
    = area_group.name
  %ul
  - for area in Area.find_all_by_area_group_id(area_group.id)
    %li.areaList
      = link_to area.name, area, :remote => true, :class => "areaLink", :id => "prufa"
.areaGroup
  No group
- for area in Area.find_all_by_area_group_id(nil)
  %li.areaList
    = link_to area.name, area, :remote => true, :class => "areaLink", :id => "prufa"

这是我得到的错误：

有什么明显的我做错了吗？

问候， 约翰

看起来第 4 行正在使用新的 Ruby 1.9 哈希语法 key: value 而不是 :key =>值。您的生产环境运行的是 Ruby 1.8 吗？如果是这样，您需要升级到 1.9，或者使用 Ruby 1.8 兼容格式：

  = link_to 'New area', '#', :id => "createNewAreaLink"
