models – so far, it’s been solving many years’ worth of database-schema problems. Here’s a quick example: Listing 1: mysite/news/models.py from django.db import models class Reporter(models.Model): full_name decouple URLs from Python code. Here’s what a URLconf might look like for the Reporter/Article example above: Listing 4: mysite/news/urls.py from django.urls import path from . import views urlpatterns request object – which contains request metadata – and the values captured in the pattern. For example, if a user requested the URL “/articles/2005/05/39323/”, Django would call the function news.views
