I'm trying to upload a file to my youtube channel using the youtube Data API

This is my upload action

videos/views.py

def upload(request):
    """
    Upload video
    :param request:
    """

    context = RequestContext(request)

    if request.method == 'POST':
        # do the following
        form_upload = VideoForm(request.POST, request.FILES)

        if form_upload.is_valid():
            uploaded_video = form_upload.save(commit=True)
            uploaded_video.category = 23
            uploaded_video.privacyStatus = 'public'

            # send this file to youtube
            initialize_upload(uploaded_video.file_on_server.path, uploaded_video)

            messages.success(request, 'Video saved.')
        else:
            messages.error(request, 'Ooops.')

    else:
        form_upload = VideoForm(instance=request.user)

    context_dict = {'form_upload': form_upload}

    return render_to_response('videos/upload.html', context_dict, context)

And this is the Python example provide by google.

I couldn't find any explanation for this error. Any help would be appreciated. Thanks.

BTW. This is my 1st experience with Python and youtube Data API.

The traceback is telling you that you're trying to call an unsupported method on a unicode (string) object. That appears to be the result of this line in views.py:

initialize_upload(uploaded_video.file_on_server.path, uploaded_video)

Here's what the example shows:

 youtube = get_authenticated_service(args)
 try:
    initialize_upload(youtube, args)

It appears you'll want to pass this function an instance of your service object, not the path of an uploaded video.

Excuse my stupidity but can you give me a hint about what should be the service object I should pass. Thanks.
In the example, it's youtube = get_authenticated_service(args). In the example, args is populated from the command line that calls the script. You'll need to look closely at the code under if __ name __ == '__ main __' to see what kind of args you'll need to pass in here.
I'm not sure about the 1st argument for initialize_upload(youtube, options): I've added the path to the file but probably it needs to go with the options. But in that case what is the argument youtube? Also I've looked at the args under the name and I've provided them all.
It comes from the line just above it in the example: youtube = get_authenticated_service(args)
But what argument do I need to send from my view.py for the youtube arg. As of now I have the following: initialize_upload(uploaded_video.file_on_server.path, uploaded_video)
