Creating a detail view for images

We will now create a simple detail view to display an image that has been saved into our site. Open the views.py file of the images application and add the following code to it:

from django.shortcuts import get_object_or_404
from .models import Image

def image_detail(request, id, slug):
    image = get_object_or_404(Image, id=id, slug=slug)
    return render(request,
                  'images/image/detail.html',
                  {'section': 'images',
                   'image': image})

This is a simple view to display an image. Edit the urls.py file of the images application and add the following URL pattern:

path('detail/<int:id>/<slug:slug>/',
     views.image_detail, name='detail'),

Edit the models.py file of the images application and add the get_absolute_url() method to the Image model, as follows:

from django.urls import reverse

class Image(models.Model):
    # ...
def get_absolute_url(self):
        return reverse('images:detail', args=...
