Advanced Form Rendering with Django Crispy Forms

[Django 2.1.3 / Python 3.6.5 / Bootstrap 4.1.3]

In this tutorial we are going to explore some of the Django Crispy Forms features to handle advanced/custom forms rendering. This blog post started as a discussion in our community forum, so I decided to compile the insights and solutions in a blog post to benefit a wider audience.

Table of Contents


Throughout this tutorial we are going to implement the following Bootstrap 4 form using Django APIs:

Bootstrap 4 Form

This was taken from Bootstrap 4 official documentation as an example of how to use form rows.


The examples below refer to a base.html template. Consider the code below:


<!doctype html>
<html lang="en">
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
  <link rel="stylesheet" href="" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
  <div class="container">
    {% block content %}
    {% endblock %}


Install it using pip:

pip install django-crispy-forms

Add it to your INSTALLED_APPS and select which styles to use:

Basic Form Rendering

The Python code required to represent the form above is the following:

from django import forms

    ('', 'Choose...'),
    ('MG', 'Minas Gerais'),
    ('SP', 'Sao Paulo'),
    ('RJ', 'Rio de Janeiro')

class AddressForm(forms.Form):
    email = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Email'}))
    password = forms.CharField(widget=forms.PasswordInput())
    address_1 = forms.CharField(
        widget=forms.TextInput(attrs={'placeholder': '1234 Main St'})
    address_2 = forms.CharField(
        widget=forms.TextInput(attrs={'placeholder': 'Apartment, studio, or floor'})
    city = forms.CharField()
    state = forms.ChoiceField(choices=STATES)
    zip_code = forms.CharField(label='Zip')
    check_me_out = forms.BooleanField(required=False)

In this case I’m using a regular Form, but it could also be a ModelForm based on a Django model with similar fields. The state field and the STATES choices could be either a foreign key or anything else. Here I’m just using a simple static example with three Brazilian states.


{% extends 'base.html' %}

{% block content %}
  <form method="post">
    {% csrf_token %}
    <table>{{ form.as_table }}</table>
    <button type="submit">Sign in</button>
{% endblock %}

Rendered HTML:

Rendered HTML with validation state:

Same form code as in the example before.
