The problem is that you are confused between the old regex-based URL mechanism and the new path-based one. If you use path, you should use the new special syntax:

path('<int:pk>', DetailView.as_view(...))

whereas if you want to use regexes, you should use the old url function (or the new alias, re_path):

url(r'(?P<pk>\d+)', DetailView.as_view(...))
