HTMX is a tool that integrates seamlessly with Django, allowing for the creation of dynamic web applications with simple settings. In this part, we will look at the overall preparations and configuration methods for integrating Django and HTMX.

Integration of Django and HTMX for dynamic web development

1. Preparations for Integrating HTMX into Django

To use HTMX in Django, follow these steps:

1.1 Loading the HTMX JavaScript Library

Add the CDN link within the <head> tag of your HTML template file.

<script src="https://unpkg.com/htmx.org"></script>

1.2 Utilizing HTMX Attributes in Django

HTMX provides various attributes to handle HTTP requests easily.

  • hx-get: Attribute for sending GET requests
  • hx-post: Attribute for sending POST requests
  • hx-target: Specify the HTML element where server response data will be inserted

HTML Code Example

<div id="content">
    <button hx-get="/get-data/" hx-target="#result">Get Data</button>
    <button hx-post="/submit/" hx-target="#result">Send Data</button>
</div>
<div id="result">Results will be displayed here.</div>

2. Handling Django Views and HTMX Requests

2.1 Handling GET Requests

from django.http import HttpResponse

def get_data(request):
    if request.method == "GET":
        return HttpResponse("<p>GET request processed!</p>")

2.2 Handling POST Requests

from django.http import HttpResponse

def submit_data(request):
    if request.method == "POST":
        return HttpResponse("<p>POST request processed!</p>")

2.3 URL Mapping

from django.urls import path
from .views import get_data, submit_data

urlpatterns = [
    path('get-data/', get_data, name='get_data'),
    path('submit/', submit_data, name='submit_data'),
]

3. Key Considerations for HTMX Integration

3.1 Handling CSRF Tokens

Django has CSRF protection enabled by default, so a CSRF token is required for POST requests. To handle POST requests with HTMX, select one of the following two methods:

1. Using HTML <meta> Tag and JavaScript Script
<meta name="csrf-token" content="{{ csrf_token }}">
<script>
    document.body.addEventListener('htmx:configRequest', function (event) {
        event.detail.headers['X-CSRFToken'] = document.querySelector('meta[name="csrf-token"]').content;
    });
</script>
2. Inserting {% csrf_token %} Inside an HTML <form> Tag
<form hx-post="/submit/" hx-target="#result">
    {% csrf_token %}
    <input type="text" name="name" placeholder="Enter your name">
    <button type="submit">Submit</button>
</form>
<div id="result"></div>

Details on handling CSRF tokens will be covered in the next part.

3.2 Distinguishing HTMX Requests

In Django 4.2 and later, you can distinguish HTMX requests using the request.htmx property.

from django.shortcuts import render

def my_view(request):
    if request.htmx:  # HTMX request
        return render(request, 'partials/snippet.html')
    return render(request, 'index.html')  # whole page

4. The Overall Flow of HTMX and Django Integration

4.1 Complete HTML Example

<!DOCTYPE html>
<html>
<head>
    <title>HTMX Demo</title>
    <script src="https://unpkg.com/htmx.org"></script>
    <meta name="csrf-token" content="{{ csrf_token }}">
    <script>
        document.body.addEventListener('htmx:configRequest', function (event) {
            event.detail.headers['X-CSRFToken'] = document.querySelector('meta[name="csrf-token"]').content;
        });
    </script>
</head>
<body>
    <div id="content">
        <button hx-get="/get-data/" hx-target="#result">GET Request</button>
        <button hx-post="/submit/" hx-target="#result">POST Request</button>
    </div>
    <div id="result">Results will be displayed here.</div>
</body>
</html>
