HAML视图中存在大量语法错误(使用狂欢引擎)

Question

我有一个简单的HAML视图，admin.html.haml:

!!!
%html{:xmlns => "http://www.w3.org/1999/xhtml"}
  %head{"data-hook" => "admin_inside_head"}

（视图相当大，为了清晰起见，我删除了大部分）

去http://localhost:3000/admin我得到：

haml-gem加载正确（扰乱了haml视图缩进，我得到了一个haml:：SyntaxError），在将spread视图切换到haml之前，它在erb视图中运行良好。

有人能建议检查什么以解决错误吗？

我发现了问题：

Spree使用了与HAML不兼容的污损（见此处）。

解决方案是在特定于环境的配置文件（development.rb、production.rb等）中禁用污损。添加此：

  # Disable deface
  config.deface.enabled = false
