URL Routing — Django

courses/urls.py

python

from django.urls import path
from . import views

# Name each URL so you can reference it by name, not string
urlpatterns = [
    path("",                 views.course_list,   name="course-list"),
    path("<slug:slug>/",     views.course_detail, name="course-detail"),
    path("api/courses/",     views.course_api,    name="course-api"),
]

myproject/urls.py — include app URLs

python

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path("admin/",    admin.site.urls),
    path("courses/",  include("courses.urls")),
    path("blog/",     include("blog.urls")),
    path("api/",      include("api.urls")),
]

# URL resolution:
# Request: GET /courses/nextjs/
# Django finds "courses/" → includes courses/urls.py
# Matches "<slug:slug>/" → calls course_detail(request, slug="nextjs")
