To add URL parameters to Python Django template url tag, we can add them after the URL name.
For instance, we write
url(r'^panel/person/(?P<person_id>[0-9]+)$', 'apps.panel.views.person_form', name='panel_person_form'),
to add a URL with url.
And then we add the parameter by writing
{% url 'panel_person_form' person_id=item.id %}
to add the person_id parameter after the URL name.
We separate multiple parameters with spaces.
