I’m having some issues getting file uploads to work correctly and the following code does not compile.

The error: overloaded method constructor File with alternatives: (java.net.URI)java.io.File <and> (java.lang.String)java.io.File cannot be applied to (play.api.mvc.MultipartFormData.FilePart[play.api.libs.Files.TemporaryFile])

The code:

def csvimport = Action(parse.multipartFormData) { request =>
      request.body.file("files[]").map { rawfile =>

        val filename = rawfile.filename 
        val contentType = rawfile.contentType
        val tmpFile = new File(rawfile)

        val reader = new CSVReader(new FileReader(tmpFile))

        Ok
      }
      .getOrElse {
        Logger.debug(request.body.toString)
        BadRequest
      }
    }

Do I need to temporarily store the file to disk before I run a CSVReader on it? Is there not a way to convert a raw file upload to a new File class in memory?

Thanks!
