In this blog post, wwill explore different methods to obtain the absolute URL in Django, along with practical examples.

One straightforward way to obtain the full absolute URL in Django is by using the HttpRequest object which is available in your views.

Using the reverse() Function

If you want to generate URLs for specific views or routes in your Django application, you can use the reverse() function along with request.build_absolute_uri() to construct the full absolute URL.

from django.urls import reverse

def my_view(request):
    # Replace 'view_name' with the name of your view or route
    url = reverse('view_name')
    full_url = request.build_absolute_uri(url)
    return full_url

This approach allows you to create absolute URLs for specific views or routes within your application.

from django.urls import reverse
from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100)

    def get_absolute_url(self):
        return reverse('myapp:view_name', args=[str(self.id)])

In this example, the get_absolute_url() method generates the absolute URL for MyModel instance.
