无法用块指定 class 和 simple_form gem

Question

我有以下表格，但出于某种原因，我无法让 HTML class 出现在结果代码中。文档表明这应该可行，但他们没有使用块的示例。我尝试了一些不同的东西，但我还没有找到正确的答案。我必须使用一个块来让自定义数据与 select.

一起出现

= simple_form_for([:admin, @theme]) do |f|
  = f.input :title_bar
  = f.input :apple_touch_icon_image, input_html: { class: 'imagepicker' } do
    = f.select :apple_touch_icon_image_id, Theme::AppleTouchIconImage.where(company: @company).map{ |i| [i.id, i.id, { 'data-img-src' => i.image.url(:thumbnail) }] }

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

Answer 1

我会尝试：

= f.input :apple_touch_icon_image do
  = f.select :apple_touch_icon_image_id, Theme::AppleTouchIconImage.where(company: @company).map{ |i| [i.id, i.id, { 'data-img-src' => i.image.url(:thumbnail) }] }, {}, { class: 'imagepicker' }
