Ruby on rails 3 产品上的Haml渲染错误

我正在MacOSX上编写一个Rails 3应用程序，它在开发和生产中都运行良好。当我使用Passenger部署应用程序时，我的一个视图中出现错误。这是视图的外观：

%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"

这就是我得到的错误：

有什么明显的我做错了吗

问候,， Johann

看起来第4行使用了新的Ruby 1.9哈希语法

key:value

，而不是

：key=>value

。您的生产环境是否运行Ruby 1.8？如果是这样，您需要升级到1.9，或者使用Ruby 1.8兼容的格式：

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

正确-我在生产中使用了1.8.x，当我根据您的建议修复链接时，错误消除了。对我来说，下一步是将Rubyon产品更新为相同的版本。非常感谢你，迪伦。
