What are Django URLconf namespaces and can you provide examples?

Django URLconf namespaces allow you to organize your URL patterns and avoid naming conflicts. For example, if you have two apps with a view named 'index', you can use namespaces to differentiate them.

How do I define a namespace in my Django project?

You can define a namespace by using the 'app_name' variable in your app's urls.py file. For example, setting 'app_name = "blog"' allows you to reference URLs in that app as 'blog:index'.

Can you show me a code example of using namespaces?

Sure! In your main urls.py, you would include the app's URLs like this: path('blog/', include(('blog.urls', 'blog'), namespace='blog')). Then, in your templates, you can use {% url 'blog:index' %} to link to the index view.

What happens if I forget to use namespaces?

If you forget to use namespaces, you might encounter naming conflicts, especially if multiple apps have views with the same name. This can lead to errors when trying to resolve URLs.
