Urls

Overview of how a request flows through a django project.

In this illustration, all requests that begin with /admin/ is sent to the admin-application.

Mapping

The general idea is to map a url to a handler. A handler (in Django called View) is simply a function that does "something", then finally returns a response. It processes the request, maybe performs authentication, fetching data from the database etc.

Inside a urls.py file, Django will recognise the variable named urlpatterns.
It's a list of path(...) entries.

A path(...) takes three arguments:

1. The url.
2. The view, or a nested urls.py file.
3. A name for the endpoint (optional).

Example:

from django.urls import path, include

from something import views as something_views

urlpatterns = [
    path('something-cbw/', something_views.HelloView.as_view(), name='hello_cbw'), # Class based view.
    path('something-fbw/', something_views.hello, name='hello_fbw'), # Function based view.
    path('other/', include('other/urls.py')), # Delegate to another file.
]
