Django — URLs

Basic URL Pattern

# mysite/urls.py
from django.contrib import admin
from django.urls import path
from blog import views

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

Path Converters

Converter	Description	Example
str	String (default)	/blog/hello/
int	Integer	/blog/42/
slug	Slug string	/blog/my-post/
uuid	UUID	/blog/550e8400-e29b-41d4-a716-446655440000/

path('blog/<int:pk>/', views.post_detail, name='post_detail'),
path('blog/<slug:slug>/', views.post_by_slug, name='post_by_slug'),

Include App URLs

# mysite/urls.py
urlpatterns = [
    path('blog/', include('blog.urls')),
]

# blog/urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('', views.post_list, name='post_list'),
    path('<int:pk>/', views.post_detail, name='post_detail'),
]

Named URLs

# In templates
<a href="{% url 'post_detail' pk=1 %}">Read More</a>

# In views
from django.shortcuts import redirect
return redirect('post_detail', pk=1)

Regex Patterns

from django.urls import re_path
re_path(r'^blog/(?P<year>[0-9]{4})/$', views.year_archive),
