語法錯誤，意外的keyword_ensure，期望以haml結尾的輸入

Question

Rails服務器出現以下錯誤，

語法錯誤，意外的keyword_ensure，預期輸入結束

= simple_form_for @recipe, html: { multipart: true } do |f|
  - if @recipe.errors.any?
    #errors
      %p
        = @recipe.errors.count
          Prevented this recipe from saving
      %ul
        - @recipe.errors.full_messages.each do|msg|
          %li= msg
  .panel-body
    = f.input :title, input_html: { class:  'form-control' }
    = f.input :description, input_html: { class: 'form-control' }

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

Answer 1

錯誤是由線條引起的

= @recipe.errors.count
  Prevented this recipe from saving

這些行中的第二行被解析為一個塊，即使沒有傳遞給該方法。 Haml然后插入end ，這最終會導致您看到額外的end錯誤。

要修復，只需縮進相同的行：

= @recipe.errors.count
Prevented this recipe from saving

或者，您可以在此處使用插值 ：

#{@recipe.errors.count} Prevented this recipe from saving

Answer 2

之后的行- if @recipe.errors.any? 需要縮進一步。

= simple_form_for @recipe, html: { multipart: true } do |f|
  - if @recipe.errors.any?
    %p
      = @recipe.errors.count
        Prevented this recipe from saving
    %ul
      - @recipe.errors.full_messages.each do|msg|
        %li= msg
  .panel-body
    = f.input :title, input_html: { class:  'form-control' }
    = f.input :description, input_html: { class: 'form-control' }

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