Django Form Wizard - Multi-Step Forms

Introduction

Django's Form Wizard is a powerful tool for creating multi-step forms in your web applications. In this comprehensive guide, we'll explore how to set up and use Django Form Wizard to split long forms into multiple steps. You'll learn how to create a seamless user experience and handle form data across different steps in the wizard.

Prerequisites

Before you begin, make sure you have the following prerequisites in place:

• Django Installed: You should have Django installed on your local development environment.
• Python Knowledge: Basic knowledge of Python programming is essential.
• Understanding of Django Forms: Familiarity with Django forms is recommended.

Step 1: Set Up a Django Form

The first step is to create a Django form that represents the data you want to collect in your multi-step form.

Sample Django Form

Create a Django form with fields for each step of your multi-step form:

from django import forms
class StepOneForm(forms.Form):
    first_name = forms.CharField(max_length=30)
    last_name = forms.CharField(max_length=30)
class StepTwoForm(forms.Form):
    email = forms.EmailField()
    phone = forms.CharField(max_length=15)
    

Step 2: Create a Form Wizard

Next, create a Django Form Wizard that manages the multi-step form process and guides the user through each step.

Sample Form Wizard

Create a Form Wizard that defines the form steps and the templates to render for each step:

from django.http import HttpResponseRedirect
from formtools.wizard.views import SessionWizardView
from .forms import StepOneForm, StepTwoForm
class MultiStepFormWizard(SessionWizardView):
    form_list = [StepOneForm, StepTwoForm]
    template_name = 'form_wizard.html'
    def done(self, form_list, **kwargs):
# Handle form submission and data processing
return HttpResponseRedirect('/success/')
    

Conclusion

Using Django Form Wizard for multi-step forms can improve the user experience and help you collect data in a structured manner. This guide has introduced you to the basics, but there's much more to explore as you customize your forms, add validation, and create a seamless form-filling process.
