ruby-on-rails - 火腿 + mustache

Question

我正在尝试使用 Haml + Mustache 创建一个博客，但是字段“description”有一个 CKEditor，因此该字段总是包含 html 标签，但 Mustache 不会呈现为 html，即使放置“description.html_safe” .

我的 helper :

def post_for_mustache(post)
{
  post: {
    category: {
      url: category_order_path(:category => post.category.to_param),
      name: post.category.name
    },
    url: category_post_path(:category => post.category.to_param,
                            :slug => post.to_param),
    title: post.title,
    comment_enabled: post.comment_enabled,
    description: post.description.html_safe,
    title_escape: URI.escape(post.title),
    url_escape: URI.escape(category_post_url(:category => post.category.to_param,
                                             :slug => post.to_param)),
  }
}
end

我的 mustache 初始化程序:

module MustacheTemplateHandler
  def self.call(template)
    haml = "Haml::Engine.new(#{template.source.inspect}).render"
    if template.locals.include? 'mustache'
      "Mustache.render(#{haml}, mustache).html_safe"
    else
      haml.html_safe
    end
  end
end
ActionView::Template.register_template_handler(:mustache, MustacheTemplateHandler)

我猜你在你的 mustache 里做这样的事情:

{{description}}

如果description包含HTML，你需要说:

{{{description}}}

来自fine manual :

Variables
[...]
All variables are HTML escaped by default. If you want to return unescaped HTML, use the triple mustache: {{{name}}}.

因此 {{description}} 将是 Mustache 编码的 HTML，但 {{{descriptipn}}} 将按原样使用 description .
