Flash 消息語法錯誤，意外的輸入結束，期待“結束”

Question

i use haml and i want to use flash messsages but i have a syntax error, when create the partial _messages.html.haml and rendering in the devise.html.haml i have this error:

Devise::SessionsController#new 中的 ActionView::SyntaxErrorInTemplate

渲染模板時遇到語法錯誤：檢查 - flash.each do |name, msg| - 如果 msg.is_a?(String) %br %div{:class => "alert alert-#{name.to_s == 'notice'?'success': 'danger'}"} %button.close{"aria -hidden" => "true", "data-dismiss" => "alert", :type => "button"} × = content_tag:div, msg, :id => "flash_#{name}"

提取的源代碼（第 8 行附近）：

    6 = content_tag :div, msg, :id => "flash_#{name}"

在終端我有這個：

我的 devise 模板 devise.html.haml app/views/layouts/devise.ZFC35FDC.80D5FCC69D2E3E369

!!!
%html
    %head
        %meta{:content => "text/html; charset=UTF-8", "http-equiv" => "Content-Type"}/
        %title Tasker

        .fullscreen
            .container
                = yield

我的部分 _messages.html.haml app/views/layouts/_messages.html.haml

- flash.each do |name, msg|
    - if msg.is_a?(String)
    %br
    %div{:class => "alert alert-#{name.to_s == 'notice' ? 'success' : 'danger'}"}
        %button.close{"aria-hidden" => "true", "data-dismiss" => "alert", :type => "button"} ×
        = content_tag :div, msg, :id => "flash_#{name}"

我試圖通過閱讀 haml 的文檔來解決這個問題，但我不知道出了什么問題。 問候。

我不熟悉 HAML，但我希望取決於if條件的內容需要縮進，因此會嘗試：

- flash.each do |name, msg|
  - if msg.is_a?(String)
    %br
    %div{:class => "alert alert-#{name.to_s == 'notice' ? 'success' : 'danger'}"}
      %button.close{"aria-hidden" => "true", "data-dismiss" => "alert", :type => "button"} ×
      = content_tag :div, msg, :id => "flash_#{name}"
