I want to return some files in a HttpResponse and I'm using the following function. The file that is returned always has a filesize of 1kb and I do not know why. I can open the file, but it seems that it is not served correctly. Thus I wanted to know how one can return files with django/python over a HttpResponse.

@login_required
def serve_upload_files(request, file_url):
    import os.path
    import mimetypes
    mimetypes.init()

    try:
        file_path = settings.UPLOAD_LOCATION + '/' + file_url
        fsock = open(file_path,"r")
        #fsock = open(file_path,"r").read()
        file_name = os.path.basename(file_path)
        mime_type_guess = mimetypes.guess_type(file_name)
        try:
            if mime_type_guess is not None:
                response = HttpResponse(mimetype=mime_type_guess[0])
            response['Content-Disposition'] = 'attachment; filename=' + file_name
            response.write(fsock)
        finally:
            fsock.close()              
    except IOError:
        response = HttpResponseNotFound()
    return response
