django-crispy-forms is a third-party package that simplifies Django's form rendering. It allows you to structure your forms in a more readable and maintainable way, and it provides a set of predefined templates to make your forms look great.

Installing django-crispy-forms ✅

First, we need to install django-crispy-forms in our project. Open your terminal and run the following command:

bash

pip install django-crispy-forms

Adding django-crispy-forms to our project ✅

Next, we need to add 'crispy_forms' to our INSTALLED_APPS list in our project's settings file:

INSTALLED_APPS = [
    # ...
    'crispy_forms',
]

Also, make sure to add the following to the bottom of your settings file:

Creating a Form with django-crispy-forms ✅

Now, let's create a simple form using django-crispy-forms. In your app's forms.py, create a form:

python

from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit

class ContactForm(forms.Form):
    name = forms.CharField(label='Your Name')
    email = forms.EmailField(label='Your Email')
    message = forms.CharField(widget=forms.Textarea, label='Your Message')

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_method = 'post'
        self.helper.add_input(Submit('submit', 'Send Message'))

Rendering the Form ✅

To render the form, in your template, include the following:

html

{% load crispy_forms_tags %}

<form method="post">
    {% csrf_token %}
    {{ form|crispy }}
</form>

Handling Form Submission ✅

In your view, handle the form submission:

python

from django.shortcuts import render
from .forms import ContactForm

def contact(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            # Handle form data here
            pass
    else:
        form = ContactForm()

    return render(request, 'contact.html', {'form': form})
