在Rails中满足条件时不会加载部分文件

Question

我在这个视图中放置了一些条件，但问题是empty_matches部分未加载，但另一方面，条件已满足。

这是视图：

%tr.form-table__row{ class: ('form-table__row--disabled' if analysis.processing?) }
  %td.form-table__data= check_box_tag "checkbox_object_ids[]", analysis.id

  %td.form-table__data
    - if analysis.results.last.total_matches != 0
      = link_to analysis.title, analysis, class: 'js-toggle', data: { href: "loading-#{analysis.id}" }
    - elsif analysis.results.last.total_matches == 0
      = link_to analysis.title, "#", class: 'js-toggle'

.
.
.

    = render partial: 'partials/modals/analyses/delete', locals: { analysis: analysis }
  - if analysis.results.last.total_matches != 0
    = render partial: 'partials/shared/loading', locals: { href: "loading-#{analysis.id}", title: 'Loading results for analysis', name: analysis.title }
  - elsif analysis.results.last.total_matches == 0
    = render partial: 'partials/shared/empty_matches', locals: { href: "loading-#{analysis.id}", title: 'No matching results for analysis', name: analysis.title }

谁能告诉我为什么empty_matches不是部分加载？满足条件loading时成功加载另一个部分analysis.results.last.total_matches != 0，但满足条件时不成功加载empty_matches部分。我在这里错了吗？

您能否向我们展示您的total_matches方法？假设它总是返回一个整数，我将使用这样的东西-

- if analysis.results.last.total_matches.zero?
  = render partial: 'partials/shared/loading', locals: { href: "loading-#{analysis.id}", title: 'Loading results for analysis', name: analysis.title }
 - else
  = render partial: 'partials/shared/empty_matches', locals: { href: "loading-#{analysis.id}", title: 'No matching results for analysis', name: analysis.title }
