What are some examples of URL routing in Django?

In Django, URL routing is handled by the urls.py file. For example, you can define a simple route like this:

from django.urls import path
from . import views

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

This maps the URL /home/ to the home view and /about/ to the about view.

Can you show me how to include parameters in the URL?

Sure! You can include parameters in the URL by using angle brackets. For example:

urlpatterns = [
    path('article/<int:id>/', views.article_detail, name='article_detail'),
]

This will capture an integer id from the URL, allowing you to access it in your view.

What about using regular expressions for more complex routing?

You can use Django's re_path for regex-based routing. For example:

from django.urls import re_path

urlpatterns = [
    re_path(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive),
]

This matches URLs like /articles/2023/ and captures the year as a parameter.

Are there any best practices for organizing URL patterns?

Yes! It's a good practice to group related URL patterns in separate urls.py files for each app and include them in the main urls.py. This keeps your routing organized and manageable.
