Answer 1

When you use reverse, use the name of the url pattern you wish to reverse.

You wish to redirect to this url:

url(
    regex=r'^NonProfit/(?P[-\w\d]+)/',
    view=NonProfitDetailView.as_view(),
    name='NonProfit'
    )

Therefore your get_absolute_url method should be:

def get_absolute_url(self):
    return reverse("NonProfit", kwargs={"slug": self.slug})
