mutagen read TemporaryUploadedFile in django

Question

I want to validate my mp3s before saving them to disk, using Mutagen. However with mutagen I can only open a file if it's on disk. Is there a way around this? I would like to be able to do this:

files = request.FILES
mp3 = files.get('mp3')
mp3_audio = MP3(mp3)

Gives me the error:

TypeError: invalid file: <TemporaryUploadedFile: test.mp3 (audio/mpeg)>

A TemporaryUploadedFile file object is already on disk, in a directory reserved for temp files. To analyze it for validity, call a method to get the full path:

files = request.FILES
mp3_temp = files.get('mp3')
mp3_audio = MP3(mp3_temp.temporary_file_path())

see docs at TemporaryUploadedFile.temporary_file_path()

Whoa, if I had known about this feature I would have saved myself so many frustrating moments. – Sebastian Olsen May 15 '16 at 12:02
Hey again, for some reason django is now no longer returning a TemporaryUploadedFile, but instead a InMemoryFile. Any ideas? It just started happening on random, and on certain files. – Sebastian Olsen May 15 '16 at 23:39
nvm, had to remove the memory file handler in settings – Sebastian Olsen May 16 '16 at 00:22
