将ActionDispatch :: Http :: UploadedFile上传到Amazon S3

Question

如何上传ActionDispatch::Http::UploadedFile到Amazon S3？

@file_data = params[:upload][:file]
s3 = AWS::S3.new
obj = s3.buckets['WeMake'].objects.create("video", file)

然后我得到这个错误:ArgumentError(:数据必须作为字符串,路径名,文件或响应#read和#eof？的对象提供):

Answer 1

我需要访问实际文件,params[:upload][:file].tempfile并为s3上传添加文件扩展名,obj = s3.buckets['Bucket'].objects.create("video.mov", @file_data.tempfile).
