one liner regex for url path with sub-paths

Using Django Forms & APIs
1

I want to have 2 URLs

localhost:8000/events
localhost:8000/events/past

<a href="{% url 'events' %}">Upcoming Events</a>
<a href="{% url 'events' 'past' %}">Past Events</a>

def events(request, timeline='current'):    
    return render(request, 'events.html')

But my regular expression is incorrect :

re_path(r'^events(/(?P<timeline>[^/]+)?)?$', views.events, name='events'),

Is there no simpler way ?

Create two different url entries for the same view but with two different names.

I had to do :

    path('events/past', views.events, kwargs = { 'timeline': 'past' }, name='events_past'),
    path('events', views.events, name = 'events'),

But I was hoping for a one-liner regex.

I’d have taken a different approach.

I would have identified these urls as /events/current/ and /events/past/ allowing me to define the url as path('events/<str:timeline>/', views.events, name='events') making the two urls more consistent with each other.
