Rails，将文件上传到服务器时获取文件名 [英] Rails, Getting a File's name when uploading a file to the server

问题描述

我在 Rails 3 中使用 AJAX 上传器和 paper_clip 并在此处上传文件:

I'm using an AJAX uploader in Rails 3, along with paper_clip and have files uploading here:

  def upload

    @photo = Photo.create({ :photo => params[:file], :title =>  params[:filename]  })

    respond_to do |format|
      format.json
    end
  end

我想将照片的标题设置为照片的文件名，但不知道如何设置，即使 params[:file] 确实有该文件并且正在上传到 S3.

I want to set the photo's title as the photo's filename, but don't know how to, even though params[:file] does have the file and is being uploaded to S3.

有什么想法吗?

谢谢

推荐答案

params[:file].original_filename 包含您要查找的文件名.

params[:file].original_filename has the filename you are looking for.
