Overview of this book

Django is a powerful framework but choosing the right add-ons that match the scale and scope of your enterprise projects can be tricky. This book will help you explore the multifarious options available for enterprise Django development. Countless organizations are already using Django and more migrating to it, unleashing the power of Python with many different packages and dependencies, including AI technologies. This practical guide will help you understand practices, blueprints, and design decisions to put Django to work the way you want it to. You’ll learn various ways in which data can be rendered onto a page and discover the power of Django for large-scale production applications. Starting with the basics of getting an enterprise project up and running, you'll get to grips with maintaining the project throughout its lifecycle while learning what the Django application lifecycle is. By the end of this book, you'll have learned how to build and deploy a Django project to the web and implement various components into the site.

Cleaning forms

We can perform validation on form fields in other ways as well. Within a form class, we can write methods that validate each field individually by writing them in this format: def clean_{{ form_field_name }}(). When doing this, only the value of the field that we are cleaning can be accessed. If we want to access other field values found in that form, we have to write a single def clean() method that will allow us to compare two fields against each other. For example, we could use the def clean() method to only require a field when another field's value is not empty.

The following two subsections break down these two concepts.

Method – clean_{{ your_field_name }}()

To clean an individual form field, follow these steps:

  1. In your /chapter_5/forms.py file, in the same ContactForm class, add a new field called email_3, as shown:
    # /becoming_a_django_entdev/chapter_5/forms.py
    from django 
    import forms
    from django.forms 
    import Form, ModelForm
    ...
