Rails HAML引擎渲染 [英] Rails HAML engine rendering

问题描述

这是怎么了?

Haml::Engine.new('= image_tag("golfer.png")').render

image_tag始终未定义(未加载ActionView :: Helpers). 我该如何解决?谢谢！

image_tag is always undefined (ActionView::Helpers in not loaded). How can I fix that? Thx!

推荐答案

我想我找到了解决方案.

I think I found the solution.

  class TagHelper
    include Singleton
    include ActionView::Helpers::TagHelper
    include ActionView::Helpers::AssetTagHelper
  end

  puts Haml::Engine.new('= image_tag("golfer.png")').render(TagHelper.instance)
