[Solved]-Passing Instance to Django formset

AuthorFormSet(queryset=Author.objects.all())

https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#changing-the-queryset

I have used it as follows the formset used is inlineformset_factory.

q = Projects.objects.get(pk=project)

formset = PayFormSet(prefix='payment',instance=q)

and then pass the formset to the template
