Question

每次我运行此代码我都会收到错误，无法找到我做错了什么，它说了一些关于synatic error的标识，期待关键字_do或＆＃39; {＆＃39;或者＆＃39;（＆＃39;。任何人都对它可能是什么有任何建议？

_form.html.haml

 = simple_form_for @pin, html: { multipart: true } do |f|
    = if @pin.errors.any?
    #errors
    %h2
    = pluralize(@pin.errors.count, "error")
    prevented this pin from saving
    %ul
    - @pin.errors.full_messages.each do |msg|
        %li = msg

        .form-group
        = f.input :title, input_html: { class: 'form-control' }

        .form-group
        = f.input :description, input_html: { class: 'form-control' }

        = f.button :submit, class: "btn btn-primary"

正如评论中指出的那样，HAML必须基于缩进进行格式化。因此，如果你有一个if语句，那么你的下一行应该从if缩进2步，而div或任何其他html元素的内容将从其父级缩进2行。您的代码看起来应该更像：

= simple_form_for @pin, html: { multipart: true } do |f|
  = if @pin.errors.any?
    #errors
      %h2
        = pluralize(@pin.errors.count, "error")
        prevented this pin from saving
        %ul
          - @pin.errors.full_messages.each do |msg|
            %li = msg

  .form-group
    = f.input :move_in, input_html: { class: 'form-control' }
  .form-group
    = f.input :move_out, input_html: { class: 'form-control' }
    = f.button :submit, class: "btn btn-primary"
