How do I use ModelFormSets in Django?

ModelFormSets in Django allow you to manage multiple instances of a model form. You can create a formset using modelformset_factory.

Can you show me a basic example of creating a ModelFormSet?

Sure! First, import the necessary modules. Then, create a formset like this:

from django.forms import modelformset_factory
from .models import YourModel

YourModelFormSet = modelformset_factory(YourModel, fields=('field1', 'field2'))

How do I handle form submission for a ModelFormSet?

You can handle form submission by checking if the request method is POST, then binding the formset to the request data and validating it. If valid, save the formset.

What if I want to add extra validation to the formset?

You can override the clean method of the formset class to add custom validation logic before saving the forms.
