我使用的宝石nested_form_fields和paperclip我的应用程序.通过上面的代码,我可以上传多个文件.但我担心的是如何使用单个file_uploader上传多个文件.我使用的名称file[]和:multiple=>true,仍然是其无法正常工作.请帮帮我.
我也需要同样的东西,但没有任何解决方案.在我正在使用的项目中
= file_field_tag :image_files, :multiple => true, name: 'image_files[]', style: 'display:none', :id => 'fileinput'

用户只需在选择此字段后选择多个文件.在控制器中,我能够使用params [:image_files]获取所有这些文件
然后我将图像构建为:
# This method builds images as per image_files params
def build_images
(params[:image_files] || []).each do |img|
@product.images.build(file: img)
end
end
