HAML 视图中存在大量语法错误（使用 spree 引擎）

Question

我有这个简单的 HAML 视图，admin.html.haml：（

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

该视图相当大，为了清晰起见，我删除了大部分内容）

转到 http://localhost:3000/admin< /code> 我得到：

SyntaxError in Spree/admin/overview#index

haml gem 已正确加载（与 haml 视图缩进混淆，我得到 Haml::SyntaxError），并且在将 spree 视图切换到 haml 之前，它与 erb 视图一起工作正常。

谁能建议检查什么来解决错误？

Answer 1

我发现了问题：

Spree 使用 deface ，它与 HAML 不兼容（请参阅 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 deface。添加这个：

  # Disable deface
  config.deface.enabled = false
