Haml：語法錯誤，意外的keyword_ensure，期望輸入結束

Question

在我的項目中，我使用haml對視圖進行編碼，並且在此部分中，服務器顯示syntax error, unexpected keyword_ensure, expecting end-of-input錯誤：

.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"

錯誤點位於第13行，最后一行。

我認為正確的語法是

= form_tag admin_articles_posts_path do
