How do I use formsets in Django?

Formsets in Django allow you to manage multiple forms on a single page. You can create a formset using formset_factory.

Can you show me a simple example of creating a formset?

Sure! First, define your form class, then create a formset using formset_factory. Here's a quick 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 render the formset in a template?

You can render the formset in your template using a loop. For example:

<form method='post'>
    {% csrf_token %}
    {{ formset.management_form }}
    {% for form in formset.forms %}
        {{ form.as_p }}
    {% endfor %}
    <button type='submit'>Submit</button>
</form>

What about handling formset validation?

You can validate the formset in your view by checking formset.is_valid(). If it's valid, you can process the data accordingly.
