💼 Career

Understanding ModelForms is essential for Django developers building data-driven web applications with clean, maintainable code.

1

Define the Book model

Create a Django model called Book with two fields: title as a CharField with max length 100, and author as a CharField with max length 50.

Django

# Define the Book model here
# Your code here

Need a hint?

Use models.CharField for text fields and set max_length as instructed.

2

Create the BookForm ModelForm class

Create a class called BookForm that inherits from django.forms.ModelForm. Inside it, define a nested Meta class that sets model = Book and fields = '__all__'.

Django

from django import forms

# Create the BookForm ModelForm class here
# Your code here

Need a hint?

Remember to import forms from django and define the Meta class inside BookForm.

3

Use the BookForm in a view function

Write a Django view function called add_book that creates an instance of BookForm and passes it to the template context with the key 'form'.

Django

from django.shortcuts import render

# Define the add_book view function here
# Your code here

Need a hint?

Create a simple view that instantiates BookForm and sends it to the template named add_book.html.

4

Render the BookForm in a template

Write the HTML code for a template named add_book.html that displays the form variable inside a <form> tag with method post. Include the CSRF token and a submit button labeled Add Book.

Django

Need a hint?

Use {{ form.as_p }} to render form fields and include {% csrf_token %} for security.
