URL Patterns with path()

Anatomy of path()

django.urls.path() takes a route string (without a leading slash), a view function, and an optional name keyword used to refer back to this URL elsewhere in the project.

from django.urls import path
from . import views

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

Multiple Static Routes

A urlpatterns list usually holds several path() entries, one per static route in the app. Each maps a distinct URL string to its own view function.

    path('', views.home, name='home'),
    path('contact/', views.contact, name='contact'),
    path('pricing/', views.pricing, name='pricing'),
]

Naming URLs for Reverse Lookups

The name= argument given to path() lets you refer to that URL elsewhere without hardcoding the string, using Django's {% url %} template tag or the reverse() function. If the URL path ever changes, only the path() call needs updating.

Note: Always name your URLs, even ones you think you will never need to look up.

from django.urls import reverse

# Anywhere in Python code:
url = reverse('about')
# In a template: <a href="{% url 'about' %}">About</a>
