ruby-on-rails - 语法错误意外的keyword_ensure，期望keyword_end

Question

我刚开始使用 Slim，在向 View 添加 if 条件时不断收到语法错误。我向用户模型添加了一个实例方法，以便可以在 View 中运行此条件。

_conversation.html.slim:

- if user.paid?

- sender = conversation.last_sender
- message = conversation.last_message
- receipts = conversation.receipts.recipient(@user).is_unread
- is_unread = receipts.count > 0 ? true : false
.outer
  div.converation class="#{is_unread == true ? 'unread' : 'read'}" onclick="#" data-href="#{conversation_path(conversation)}"
    .col_1
      img alt="" src="#{is_unread == true ? '/assets/un_read.png' : '/assets/read.png'}" /
      span.conversation_avatar
        =link_to "/profile/#{sender.id}" do
          img alt="" src="#{sender.avatar.image_url(:avatar)}" /
      h5 = sender.username
      strong 
        = sender.age
        ', 
        = sender.gender
        ',
        = sender.sexuality
      small
        br
        = sender.location.city
        ',
        = sender.location.state
    .col_2
      span = message.subject
      p = message.body
    .col_3
      strong = extract_date(message.created_at)
      small = extract_time(message.created_at)
  form action="#" 
    fieldset
      input type="checkbox" class="conversation_checkbox"

- else

缩进在Slim中非常重要。您没有在第一行中缩进任何内容，if user.paid?;您需要这样做，否则您将生成一个没有正文的 if 语句。
