{% url 'project-details' project.pk %}

Answer 1

You defined your url patterns as using a named group, so you need to pass named arguments to the urltag, ie {% url 'project-details' pk=project.pk %}.

Also, you want to start your url patterns with a caret to make sure they dont match more than needed, ie: ^project/$ and ^project/(?P<pk>\d+)/$.
