from UploadExpert.celery import app

# Create your views here.

demo_titles =['title1', 'title2', 'title3']


@app.task(ignore_result=True)
def GetTitles(video_id):
    video = Videos.objects.get(pk=video_id)

    for title in demo_titles:
        t = TitleVideo(
            title=title,
            video_id=video.id
            )
