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: File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py" in get_response 115. response = callback(request, *callback_args, **callback_kwargs) File "/usr/local/lib/python2.7/dist-packages/django/contrib/auth/decorators.py" in _wrapped_view 25. return view_func(request, *args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/django/views/generic/base.py" in view 68. return self.dispatch(request, *args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/django/views/generic/base.py" in dispatch 86. return handler(request, *args, **kw…

Accepted Answer

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.
