Haml：语法错误，意外 keyword_ensure，预期输入结束

Question

在我的项目中，我使用 haml 对视图进行编码，在此部分中，服务器显示 syntax error, unexpected keyword_ensure, expecting end-of-input 错误：

.col-xs-12#new_posts_form 
  %h2= "New posts"
  = form_tag admin_articles_posts_path
    - @posts.each_with_index do |post,i|
      = fields_for "posts[#{i}]", post do |f| 
        .col-xs-12
          %label Content
          = f.text_area :content, placeholder: "Content", class: "form-control"
        .col-xs-12
          %label Publishing date
          =f.date_field :start_date, placeholder: "yyyy-mm-dd", class: "form-control"
        .col-xs-12
          = f.submit "Next", class: "btn btn-default"

错误指向第 13 行，最后一行。
