Making JavaScript Calls from Django Templates to DRF Endpoints

Making JavaScript Calls from Django Templates to DRF Endpoints

When integrating Django REST Framework (DRF) with a traditional Django template, you can use JavaScript (via the Fetch API or jQuery AJAX) to call your DRF API endpoints. This guide provides step-by-step examples and covers important considerations like CSRF tokens, authentication, relevant settings/middleware, and best practices.

Overview of the Approach

In a typical setup, your Django app renders an HTML template, and that page includes JavaScript which calls DRF endpoints (usually returning JSON). If the page and the DRF API share the same domain and session, you can leverage Django’s session authentication for AJAX calls. If the API is hosted on a different domain or meant for third-party clients, you’ll likely use token-based authentication instead. In either case, you must handle CSRF protection for any “unsafe” HTTP methods (POST, PUT, PATCH, DELETE) when making requests from a Django template.

Below, we’ll walk through examples using both the Fetch API …

Introducing django-chunked-upload

Introducing django-chunked-upload

django-chunked-upload is a Django add-on (a “Django app”) that makes it easy to upload very large files by splitting them into smaller pieces, or chunks. Instead of sending one giant file all at once, the browser sends many smaller parts to the server. The library then stitches these chunks back together. In practice, this means a user can resume an upload if something goes wrong – for example, if the network drops, they don’t have to restart from zero. In fact, the library’s description says it “enables users to upload large files… in multiple chunks, with the ability to resume if the upload is interrupted”. One blog explains the idea simply: “you break a file into chunks, and upload them separately instead of the entire thing in one go”. Django-chunked-upload automates this process on the server side so you don’t have to write all the logic yourself.

How AI Tools Transformed My Approach to Client Web Development

How AI Tools Transformed My Approach to Client Web Development

A few years ago, I followed a predictable path when clients approached me for web development. When a YouTube creator came to me recently needing a website to support her channel and improve its SEO, I found myself at a familiar crossroads – but this time, I made a different choice.

The Old Way: Defaulting to CMS

In the past, my instinct would have been to reach for WordPress or Joomla. These content management systems offered a comfortable familiarity and the promise of rapid deployment. Within hours, I could have a functional site up and running.

But there was always a trade-off. I'd spend days or weeks wrestling with themes, plugins, and custom code to bend these platforms to my client's specific needs. The initial speed came with a long tail of customization work, often leading to compromises in functionality or design.

The Power of Django: Building Scalable Web Applications Quickly

When it comes to building web applications, developers are always on the lookout for frameworks that strike the right balance between speed, scalability, and robustness. Django, a high-level Python web framework, has earned a reputation for helping developers rapidly build secure, scalable, and maintainable web applications.

In this post, we'll explore the power of Django, its key features, and how it enables you to develop applications efficiently without compromising on performance or flexibility.


What Makes Django Stand Out?

Django is more than just a framework—it's a full-fledged web development ecosystem that provides everything you need to build powerful web applications, from user authentication to data management and everything in between. Here's why Django stands out as one of the best choices for building scalable web applications:

1. Rapid Development

One of the core philosophies behind Django is “Don’t Repeat Yourself” (DRY). This means that Django encourages code reusability, which …

The Practical Guide to Django Templates

The Practical Guide to Django Templates

Django’s templating system is a powerful way to separate presentation from business logic. In this guide, we’ll build a robust base.html template that leverages popular front-end libraries such as Bootstrap 5.3, Bootstrap Icons, Font Awesome, and Google Fonts. Additionally, we’ll incorporate a responsive navbar, a footer, and Django’s messaging framework with JavaScript that automatically dismisses alerts after 5 seconds. We’ll also create three sample pages—home.html, about.html, and contact.html—to demonstrate how to extend the base template.


1. Setting Up the Base Template (base.html)

The base.html template serves as the skeleton for all your pages. By placing common elements—like the header, footer, and scripts—in one file, you ensure consistency and ease future maintenance.

Key Elements in base.html:

  • CSS Frameworks and Icon Libraries:
    We load Bootstrap 5.3 via its CDN, alongside Bootstrap Icons and Font Awesome for a variety of icon options. …

How can I handle multiple types of messages in a single Django view

How can I handle multiple types of messages in a single Django view

Handling multiple types of messages in a single Django view can be achieved by leveraging Django's messaging framework and customizing how messages are added and displayed. Here's a step-by-step guide on how to handle different types of messages effectively:

1. Adding Messages with Different Levels

Django's messaging framework supports different levels of messages (e.g., DEBUG, INFO, SUCCESS, WARNING, ERROR). You can add messages with specific levels in your view:

 
from django.contrib import messages def my_view(request): # Add messages with different levels messages.debug(request, "This is a debug message.") messages.info(request, "This is an informational message.") messages.success(request, "This is a success message.") messages.warning(request, "This is a warning message.") messages.error(request, "This is …
How can I customize the appearance of messages in Django templates

How can I customize the appearance of messages in Django templates

Customizing the appearance of messages in Django templates involves modifying the HTML structure and applying CSS styles to match your project's design. Here's how you can do it:

1. Modifying the HTML Structure

To change the HTML structure of messages, you can modify the template where messages are displayed. Typically, messages are displayed using a loop in your template:

 
{% if messages %} <ul class="messages"> {% for message in messages %} <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li> {% endfor %} </ul> {% endif %}

If you want to wrap the message text in a <span> tag, you can modify the template like this:

 
{% if messages %} <ul class="messages"> {% for message in messages %} <li{% if message.tags %} class="{{ message.tags }}"{% endif %}> …
How does GZip middleware improve Django template performance

How does GZip middleware improve Django template performance

GZip middleware improves Django template performance by compressing HTTP responses, which reduces the amount of data transferred over the network. This compression significantly decreases page load times, enhancing user experience and improving overall application performance. Here’s how GZip middleware contributes to better template performance:

How GZip Middleware Works

  1. Compression: GZip middleware compresses the HTML output of your templates before sending it to the client. This reduces the size of the data being transferred, which is particularly beneficial for large templates or those with extensive content.

  2. Faster Page Loads: By reducing the data size, GZip compression accelerates page loading times. This is crucial for user experience, as faster page loads can lead to higher engagement and better search engine rankings.

  3. Bandwidth Savings: Compressing responses also saves bandwidth, which can be cost-effective for high-traffic sites or applications with limited bandwidth resources.

Configuration and Considerations

How can I optimize template performance in Django

How can I optimize template performance in Django

Optimizing template performance in Django is crucial for enhancing user experience and reducing server load. Here are several strategies to improve template rendering efficiency:

1. Simplify Templates and Logic

  • Avoid Complex Logic: Keep templates simple by moving complex logic to views or model methods. This improves maintainability and reduces processing time within templates.

  • Use Template Tags: For logic that must be executed within templates, use custom template tags to encapsulate complexity.

2. Optimize Database Queries

  • Use select_related() and prefetch_related(): Minimize database hits by fetching related objects in a single query.

  • Limit Retrieved Data: Use values() or values_list() to retrieve only necessary fields, reducing memory usage and query time.

3. Enable Template Caching

  • Cached Template Loader: Use the django.template.loaders.cached.Loader to cache compiled templates. This avoids recompiling templates on each request, significantly improving performance.

4. Optimize Template Structure

  • Avoid Heavy Fragmentation: While {% include %} is …
