Haml渲染生产出错

我正在Mac OSX上编写Rails 3应用程序，它在开发和生产环境下运行良好。当我使用Passenger部署应用程序时，在我的某个视图中出现错误。这是该视图的样子：Haml渲染生产出错

%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，我做错了什么？

问候，约翰

它看起来像4号线使用的key: value代替:key => value新的Ruby 1.9的哈希语法。您的生产环境是否运行Ruby 1.8？如果是这样，你需要升级到1.9，或者使用Ruby 1.8兼容格式：

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

正确 - 我在生产中使用1.8.x，。对我来说，下一步是更新生产中的红宝石版本。非常感谢Dylan。 – gugguson
