通过Django在Dailymotion中上传电影文件

Question

I am developping a webapplication for a movie challenge organised by an association. My association and I want to directly upload submitted movies to the Dailymotion account of the association.

I already done tests localy to understand how to upload movie in Dailymotion and it works fine with a simple Python script, the Python SDK provided by Dailymotion, and using the direct path of the movie stored in my hard drive. It works like a charm so I tried to implement it in the Django application I am developping.

I don't understand what happens, but if I try through the form, it returns me this error:

TypeError at /a/bioinfuse/submit_movie/15

Here is the submit_video view:

def submit_movie(request, member):
    def submit_movie(d, file, data, m_id):
        q_movie = Movie.objects.get(id=m_id)
        url = d.upload(file)
        movie = d.post('/me/videos',
                       {'url': url, 'title': data['title'],
                        'published': 'true', 'channel': 'tech',
                        'private': 'true',
                        'description': data['description']})
        url = d.get('/video/'+movie,
                    {'fields': 'embed_url', 'id': id_movie})['embed_url']
        q_movie.url = url
        q_movie.save()

    context = base(request)
    role = Member.objects.get(user=member).role
    member = Member.objects.get(user=member)
    challenge = Challenge.objects.filter(is_open=True).order_by('stop_date')[0]
    if request.method == 'GET':
        submit_movie_form = SubmitMovieForm({'submit_date': now()})
    else:
        submit_movie_form = SubmitMovieForm(request.POST, request.FILES)

        if submit_movie_form.is_valid():
            title = submit_movie_form.cleaned_data['title']
            description = submit_movie_form.cleaned_data['description']
            submit_date = submit_movie_form.cleaned_data['submit_date']
            file_movie = request.FILES['file_movie']
            associated_key = AssociatedKey.objects.get(associated_key=member.associated_key)
            register_movie = Movie(challenge=challenge,
                                   associated_key=associated_key,
                                   title=title,
                                   description=description,
                                   submit_date=submit_date)
            register_movie.save()
            m_id = register_movie.id

            d = dailymotion.Dailymotion()
            d.set_grant_type('password', api_key=API_KEY,
                             api_secret=API_SECRET, scope=['manage_videos'],
                             info={'username': USERNAME, 'password': PASSWORD})
            data = {'title': title, 'description': description}
            job = pp.Server()
            job.submit(submit_movie, (d, file_movie, data, m_id))
            return HttpResponseRedirect(reverse('bioinfuse:index'))

    context['submit_movie_form'] = submit_movie_form
    context['role'] = role
    return render(request, "submit_movie.html", context)

The SubmitMovieForm form:

class SubmitMovieForm(forms.ModelForm):
    file_movie = forms.FileField(label="Votre vidéo")
    class Meta:
        model = Movie
        exclude = ('challenge', 'associated_key', 'movie_url', 'published')

And the template form used:

<form action="{% url 'bioinfuse:submit_movie'  user.id %}" method="post" enctype="multipart/form-data">{% csrf_token %}
    <fieldset>
        {{ submit_movie_form.as_p }}
        <input type="submit" value="Mettre à jour">
    </fieldset>
</form>

I wonder if Django wants that I first upload the movie in the server, but I wish to directly upload the movie file in Dailymotion, without having to store the file in the server.

Do you know how I can manage to directly upload the movie in Dailymotion without creating a temporary file in our server? If it is possible, of course.

Want to see more code? Go on this GitHub repository , the application name is bioinfuse.

TL;DR: How to upload a movie in Dailymotion, through Django, without storing it on the server of the webapplication?

Thanks in advance!

Answer 1

No it is not possible. The file need to be temporarily inside your server because the request go through your server.
