What are Django URL namespaces and how do I use them?

Django URL namespaces allow you to organize your URL patterns and avoid naming conflicts. You can define a namespace for a set of URLs in your application.

Can you show me an example of how to define a URL namespace?

Sure! In your urls.py, you can use the app_name variable to define a namespace. For example:

app_name = 'myapp'
urlpatterns = [
    path('home/', views.home, name='home'),
]

How do I reference a namespaced URL in a template?

You can reference a namespaced URL in a template using the url template tag. For example:

<a href="{% url 'myapp:home' %}">Home</a>

What happens if I don't use namespaces?

Without namespaces, you might encounter naming conflicts if multiple apps have URLs with the same name, leading to confusion.
