Re: NoReverseMatch

hi
this is for the id.
your url must be like this:

url(r'^events/((?P<id>\d+))/delete/$', views.delete_event, name='delete_event'),

you also need to give an amount in your template to the id:

action="{% url 'cal:delete_event' id=an_event_id %}">

Or, the variable 'id' either doesn't exist or isn't populated, also causing the URL look-up to fail, based on the traceback you provided.

django.urls.exceptions.NoReverseMatch: Reverse for 'delete_event' with arguments '('',)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['cal/events/(\\d+)/delete_event$']

The traceback in this case is a bit misleading because of the missing named group in the regex. 

You'll need to fix both issues before the resolution will succeed.
