23 / 30Django Views and URL RoutingHardPython - Django Framework

Scenario: Hari's Blog Application URL Structure

  1. Hari should create a project-level urls.py with `path('blog/', include('blog.urls', namespace='blog'))` and a blog app urls.py with patterns like `path('post/<int:id>/', views.post_detail, name='post_detail')`. This allows him to reference the URL as 'blog:post_detail' in templates.

  2. Hari should define all URL patterns directly in the project's urls.py file to avoid confusion with nested namespaces.

  3. Hari must use re_path() instead of path() if he wants to use namespaces in his blog application.

  4. Hari should create separate URLconf files for each blog post, which is the recommended Django pattern for scalable applications.

Show answer & explanation

Correct answer

Hari should create a project-level urls.py with `path('blog/', include('blog.urls', namespace='blog'))` and a blog app urls.py with patterns like `path('post/<int:id>/', views.post_detail, name='post_detail')`. This allows him to reference the URL as 'blog:post_detail' in templates.

Explanation

Nested include() with namespaces creates a hierarchical URL structure where app-level URLs can be included in project-level URLs, and each level can have its own namespace for organization.
