- Released December, 2017
- Major features:
- Only supports Python 3.4 and above
- Mobile-friendly admin interface
- Simplified URL routing syntax
from django.conf.urls import url
urlpatterns = [
url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive),
]- Required users to understand regular expressions
- Passes URL parameters as strings to your views
from django.urls import path
urlpatterns = [
path('articles/<int:year>/', views.year_archive)
]- Simpler for new users (no more regex!)
- Handles coercion into the designated type
- Can be extended with ... functions
from django.urls import re_path
urlpatterns = [
# support date paths: /date/2018-01-18
re_path(r'^date/(?P<year>[0-9]{4})-(?P<month>[0-9]{2})-(?P<day>[0-9]{2})$', views.day_archive)
]- You can use
django.urls.re_pathto add regex-based URLs - (you can also just keep using the old
urlfunction)

Register custom converters with
django.urls.register_converter- The documentation suggests doing this in your
urls.py
- The documentation suggests doing this in your
-
register_convertertakes two arguments:- A Converter
- The "type name" used in the URL
import datetime
from django.urls import register_converter
class IsoDateConverter:
regex = '\d{4}-\d{2}-\d{2}'
def to_python(self, value):
return datetime.datetime.strptime(value, '%Y-%m-%d').date()
def to_url(self, value):
return str(value)
register_converter(IsoDateConverter, 'isodate')- The result of
to_pythonwill be passed to your view - If an exception is raised, the next URL pattern will be used
- Simple to test:
def test_isodate(self):
response = self.client.get('/url/2018-01-18/').json()
self.assertEqual('isodate', response['url_name'])- Follow me on Twitter: @sesh
