我有一个rails应用程序最初使用Paperclip进行文件上传,但是,当我看到CarrierWave显然在表格重新显示时有一个“持久上传”类型功能时,我决定尝试一下.
在我看来,我有以下几点：
= f.input :attachment = f.hidden_field :attachment_cache
如果表单验证失败并重新显示,则正确缓存文件,但是当我更正验证错误并重新提交时,不会处理附件.

它似乎是通过params中的attachment_cache正确传递附件,但它没有保存附件,因为它没有params [：model] [：attachment]字段.
它没有说明在载波部分上的任何进一步的步骤,使得上传在CarrierWave GitHub上的表格重新显示中起作用.
