How can I customize formsets in Django?

You can customize formsets in Django by creating a custom formset class and overriding methods like __init__ and save.

Can you show me an example of a custom formset?

Sure! Here's a simple example:

from django import forms
from django.forms import formset_factory

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)

MyFormSet = formset_factory(MyForm)

How do I add validation to my custom formset?

You can add validation by overriding the clean method in your custom formset class. This allows you to check the data across all forms.

What if I want to limit the number of forms in the formset?

You can set the max_num parameter when creating the formset, like this:

MyFormSet = formset_factory(MyForm, max_num=5)
