Update queryset in Django in following situation?

Question

I want to update data in Django model like this:

 video_id = request.POST['video_id']
     # Get the form data and update the data

 video = VideoInfoForm(request.POST)

 VideoInfo.objects.filter(id=video_id).update(video)

  return HttpResponseRedirect('/main/')

The new data is supplied by user in a form. I want to update data with id=video_id. This gives me following error:

update() takes exactly 1 argument (2 given)
Traceback:

Answer 1

The update function only take keyword arguments, no generic arguments, that's why you get the update() takes exactly 1 argument (2 given) error message.

Try:

VideoInfo.objects.filter(id=video_id).update(foo=video)

Where your models are :

class Video(models.Model):
    ...

class VideoInfo(models.Model):
    foo = models.ForeignKey(Video)
    ...

Note that the doc linked in comment by lazy functor shows the signature of the update function.
