Django ModelFormSets

Last Updated : 02 Dec, 2025

Django ModelFormsets allow managing multiple model-based forms on a single page. They enable creating, updating, or deleting multiple instances of a model at once, using a group of forms tied to the model's fields. Each form in the formset corresponds to a single model instance.

Using ModelFormsets

Consider a Django project with an app containing the GeeksModel model.

In models.py:

Python

from django.db import models

class GeeksModel(models.Model):
    title = models.CharField(max_length=200)
    description = models.TextField()

    def __str__(self):
        return self.title

title and description are the fields representing model data.
__str__ method helps display the model instances by their title.

Creating a ModelFormset

To create a formset for this model, use Django’s modelformset_factory function.

Python

from django.forms import modelformset_factory
from .models import GeeksModel

GeeksFormSet = modelformset_factory(GeeksModel, fields=['title', 'description'])

This creates a formset class that generates forms based on the GeeksModel.

ModelFormsets in Views

In views.py, create a view to render and process the formset:

Python

from django.shortcuts import render
from django.forms import modelformset_factory
from .models import GeeksModel

def modelformset_view(request):
    GeeksFormSet = modelformset_factory(GeeksModel, fields=['title', 'description'], extra=3)
    
    if request.method == 'POST':
        formset = GeeksFormSet(request.POST)
        if formset.is_valid():
            formset.save()  # Saves all valid forms to the database
    else:
        formset = GeeksFormSet()
        
    return render(request, 'home.html', {'formset': formset})

extra=3 argument means three empty forms will be displayed for adding new entries.
On POST, the formset is validated and saved automatically if valid.

Rendering ModelFormsets in Templates

In home.html, render the formset:

html

<form method="POST" enctype="multipart/form-data">
    {% csrf_token %}
    {{ formset.as_p }}
    <input type="submit" value="Submit">
</form>

management_form is required to keep track of formset data and validate the forms correctly.
formset.as_p renders each form’s fields wrapped in <p> tags.
