ruby-on-rails - 在HAML中，语法错误，我未放置意外的 ')'

Question

我使用以下代码在HAML中呈现选项的下拉列表:

  - @campaigns.each do |campaign|
    %tr{class: 'tr_' + cycle('odd', 'even'), id: "#{campaign.to_param}"}
      %td= link_to campaign.name, campaign
      %td= campaign.synopsis
      %td= campaign.focus_area
      %td= number_to_currency(campaign.goal_in_dollars)
      %td= campaign.approval_requested_at //line 34
      %td= link_to 'Approve', approve_admin_campaign_path(campaign)//line 35
      %td= form_tag({controller: "admin/campaign", action: "deny"}, method: "post") do //line 36
      = text_field_tag :reason, params[:reason] //line 37
      = submit_tag("Deny") //line 38

但是，出现错误:

/Users/user/rails_projects/wdi/app/views/admin/campaigns/index.haml:34: syntax error, unexpected ')'

这个错误来自哪里？我没有添加括号或换行符

表单标签没有缩进。更改为

%td
  = form_tag({controller: "admin/campaign", action: "deny"}, method: "post") do //line 36
    = text_field_tag :reason, params[:reason] //line 37
    = submit_tag("Deny")
