Question

我在使用fields_for的表单中使用嵌套字段。我需要动态添加多个附件并提交表单。在控制台中我得到了附件的参数

"reminder"=>{"message_addl_attachments_attributes"=>{"1380913359931"=>{"attachment"=>#<File:/tmp/RackMultipart20131005-4343-1cxemfz-0>}}

我不确定如何在控制器中处理此问题并保存附件。我已经正确地建立了协会。在控制器中，我这样做。

    def create_reminder
    @reminder = Reminder.new
    @addl = @reminder.message_addl_attachments.build(params[:reminder][:message_addl_attachments])
    @addl.save
end

请在控制台中找到完整的参数。

Completed in 459ms (DB: 217) | 302 Found [http://localhost/reminder_plugin/create_reminder]

但它没有将它保存在我的rails公共目录中......在db中它也保存了空值..请帮忙。

              <% l.fields_for :attachments do |a| %>

您首先需要检查的内容：

ImageMagick已安装并正常工作
您的表单是否具有属性“multipart =＆gt; true”

希望这会有所帮助：）
