How to Get the Current Domain Name in Django Template?

Are you tired of hardcoding domain names in your Django templates? Do you want to make your application more flexible and scalable? Well, you’re in luck because in this article, we’ll show you how to get the current domain name in Django template. Whether you’re a seasoned Django developer or just starting out, this tutorial is perfect for you!

Why Do You Need to Get the Current Domain Name?

There are several reasons why you might need to get the current domain name in your Django template. Here are a few:

• You want to generate absolute URLs for your web application.

• You need to display the current domain name in your template for branding purposes.

• You want to create a dynamic domain-based navigation system.

• You’re building a multi-tenant application and need to retrieve the current domain for each tenant.

Method 1: Using the `HttpRequest` Object

The first method to get the current domain name in Django template is by using the `HttpRequest` object. This method is straightforward and easy to implement.

In your view function, you can access the `HttpRequest` object as follows:

from django.http import HttpResponse
from django.shortcuts import render

def my_view(request):
    current_domain = request.get_host()
    return render(request, 'my_template.html', {'current_domain': current_domain})

In your template, you can then access the `current_domain` variable as follows:

<p>The current domain name is {{ current_domain }}.</p>

Method 2: Using a Custom Template Tag

The second method to get the current domain name in Django template is by creating a custom template tag. This method provides more flexibility and reusability.

First, create a new file called `domain_tags.py` in your app’s `templatetags` directory:

from django import template
from django.http import HttpRequest

register = template.Library()

@register.simple_tag(takes_context=True)
def get_current_domain(context):
    request = context['request']
    return request.get_host()

Then, in your template, load the custom template tag and use it as follows:

{% load domain_tags %}

<p>The current domain name is {% get_current_domain %}.</p>

Method 3: Using a Context Processor

The third method to get the current domain name in Django template is by using a context processor. This method provides a global solution that can be used across all templates.

Create a new file called `context_processors.py` in your app’s directory:

from django.http import HttpRequest

def add_current_domain(request):
    return {'current_domain': request.get_host()}

Then, add the context processor to your `settings.py` file:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'myapp.context_processors.add_current_domain',
            ],
        },
    },
]

Finally, in your template, you can access the `current_domain` variable as follows:

<p>The current domain name is {{ current_domain }}.</p>

Method 4: Using a Middleware

The fourth method to get the current domain name in Django template is by using a middleware. This method provides a flexible solution that can be used across all templates and views.

Create a new file called `middleware.py` in your app’s directory:

class GetCurrentDomainMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        return response

    def process_template_response(self, request, response):
        response.context_data['current_domain'] = request.get_host()
        return response

Then, add the middleware to your `settings.py` file:

MIDDLEWARE = [
    # ...
    'myapp.middleware.GetCurrentDomainMiddleware',
    # ...
]

Finally, in your template, you can access the `current_domain` variable as follows:

<p>The current domain name is {{ current_domain }}.</p>
