Does Django close and delete TemporaryUploadedFiles and InMemoryUploadedFiles?

Question

I have read through all the documentation for TemporaryUploadedFiles and InMemoryUploadedFiles but they talk never about clean up. I know that Python Temporary Files need to be closed in order to be deleted automatically.

@api_view(['POST', ])
def test(request):
    #img is type InMemoryUploadedFile
    for img in request.FILES.getlist('images'):
        Model.objects.image = img
        Model.save()

    #vid is type TemporaryUploadedFile
    for vid in request.FILES.getlist('videos'):
        Model.objects.video = vid
        Model.save()

In the code above, are the TemporaryUploadedFiles and InMemoryUploadedFiles deleted and cleaned up automatically?

Answer 1

These files are closed, WSGI handler can provide a method called close and that method is called post-processing of the request.

Django source code (http/request.py)

class HttpRequest:
  ...
  def close(self):
     if hasattr(self, '_files'):
        for f in chain.from_iterable(list_[1] for list_ in self._files.lists()):
           f.close()

Edit:

Django globally configures two types of file uploader InMemory and Temp file. All these classes implement theclose method, the close method of request object is registered as _resource_closers and these methods are called from HttpResponseBase's close method.
