Understanding named URLs is essential for Django developers to write clean, maintainable, and scalable web applications.

1

Create a URL pattern for the home page

In your Django app's urls.py, create a URL pattern for the home page path '' that points to a view function called home_view. Use the exact path '' and view name home_view.

Django

# Your code here

Need a hint?

Use path('', home_view) inside urlpatterns list.

2

Add a name to the URL pattern

Modify the URL pattern for the home page to add the name 'home' using the name argument in the path() function.

Django

from django.urls import path
from .views import home_view

urlpatterns = [
    # Add name='home' to the path below
    path('', home_view, name='home'),
]

Need a hint?

Add name='home' inside the path() call.

3

Create the home_view function

In your views.py, create a function called home_view that takes a request argument and returns a simple HttpResponse with the text 'Welcome to the Bookstore'. Import HttpResponse from django.http.

Django

# Your code here

Need a hint?

Define home_view that returns HttpResponse('Welcome to the Bookstore').

4

Use the named URL in a template

In your Django template file base.html, create a link to the home page using the named URL 'home' with the Django template tag {% url 'home' %}. The link text should be Home. Write the full anchor tag.

Django

Need a hint?

Use <a href="{% url 'home' %}">Home</a> to link using the named URL.
