Django Add Master Template

Welcome to The Coding College, where we simplify coding concepts for aspiring developers. In this tutorial, we’ll guide you through creating and using a master template in Django. Master templates help you build web applications with a consistent design and structure, improving both development speed and user experience.

What is a Master Template in Django?

A master template is a reusable HTML template that defines the overall structure of your web pages. Commonly referred to as a “base template,” it includes elements shared across multiple pages, such as:

  • Headers
  • Navigation bars
  • Footers

Using a master template, you can ensure consistency in your application’s design while reducing repetitive code.

1. Setting Up Your Project

Before adding a master template, ensure you have a Django project and app set up.

Create a Django Project and App

django-admin startproject myproject  
cd myproject  
python manage.py startapp myapp

Update INSTALLED_APPS in settings.py to include myapp:

INSTALLED_APPS = [  
    ...  
    'myapp',  
]

2. Configure Template Settings

Ensure your TEMPLATES configuration in settings.py is set up correctly:

TEMPLATES = [  
    {  
        'BACKEND': 'django.template.backends.django.DjangoTemplates',  
        'DIRS': [BASE_DIR / 'templates'],  # Custom templates directory  
        'APP_DIRS': True,  
        'OPTIONS': {  
            'context_processors': [  
                'django.template.context_processors.debug',  
                'django.template.context_processors.request',  
                'django.contrib.auth.context_processors.auth',  
                'django.contrib.messages.context_processors.messages',  
            ],  
        },  
    },  
]

3. Create the Master Template

In your project directory, create a folder named templates. Inside it, create a file called base.html.

Example Master Template (base.html):

<!DOCTYPE html>  
<html lang="en">  
<head>  
    <meta charset="UTF-8">  
    <meta name="viewport" content="width=device-width, initial-scale=1.0">  
    <title>{% block title %}The Coding College{% endblock %}</title>  
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css">  
</head>  
<body>  
    <header class="bg-primary text-white text-center py-3">  
        <h1>The Coding College</h1>  
    </header>  

    <nav class="navbar navbar-expand-lg navbar-dark bg-dark">  
        <div class="container-fluid">  
            <a class="navbar-brand" href="/">Home</a>  
            <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">  
                <span class="navbar-toggler-icon"></span>  
            </button>  
            <div class="collapse navbar-collapse" id="navbarNav">  
                <ul class="navbar-nav">  
                    <li class="nav-item">  
                        <a class="nav-link" href="/about/">About</a>  
                    </li>  
                    <li class="nav-item">  
                        <a class="nav-link" href="/contact/">Contact</a>  
                    </li>  
                </ul>  
            </div>  
        </div>  
    </nav>  

    <main class="container my-4">  
        {% block content %}  
        <!-- Page-specific content goes here -->  
        {% endblock %}  
    </main>  

    <footer class="bg-dark text-white text-center py-3">  
        <p>© 2024 The Coding College. All Rights Reserved.</p>  
    </footer>  

    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>  
</body>  
</html>

Key Features of the Master Template:

  • {% block title %}: Placeholder for page-specific titles.
  • {% block content %}: Placeholder for the main content of each page.
  • Header, navigation, and footer are consistent across all pages.

4. Extend the Master Template

To create a page using the master template, use Django’s {% extends %} tag.

Example Page Template (home.html):

{% extends 'base.html' %}  

{% block title %}Home - The Coding College{% endblock %}  

{% block content %}  
<h2>Welcome to The Coding College</h2>  
<p>Learn Django and other programming skills with our easy-to-follow tutorials.</p>  
{% endblock %}

5. Define Views and URLs

Create a View

In views.py, create a view to render the home.html template:

from django.shortcuts import render  

def home(request):  
    return render(request, 'home.html')

Add a URL

In urls.py, add a URL pattern for the home page:

from django.urls import path  
from . import views  

urlpatterns = [  
    path('', views.home, name='home'),  
]

6. Run the Development Server

Start the development server:

python manage.py runserver

Visit http://127.0.0.1:8000/ to see the home page styled with the master template.

Benefits of Using a Master Template

  1. Consistency: Maintain a uniform design across all pages.
  2. Efficiency: Reuse code and reduce duplication.
  3. Flexibility: Easily update global elements like headers and footers without modifying individual templates.
  4. Scalability: Simplify management as your application grows.

Best Practices for Master Templates

  1. Organize Your Templates: Use directories to keep templates structured. For example: templates/ base.html home.html about.html
  2. Use Template Inheritance: Extend the master template for all pages to maintain consistency.
  3. Minimize Inline Styles: Use CSS files for styling to ensure separation of concerns.
  4. Test Responsiveness: Ensure your master template is mobile-friendly.
