Haml的：語法錯誤，意想不到的keyword_ensure，預計最終的輸入

Question

在我的項目，我使用haml編寫的意見，並在此部分，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" 

錯誤點第13行，最後一個。

Answer 1

我認爲正確的語法是

= form_tag admin_articles_posts_path do
