Django で、URLリゾルバのビュー名を列挙するコード

Django の URL 解析機 (URLリゾルバ) で使うURL名 ( reverse() の第一引数に入れるやつ )の一覧を表示するコード

from django.urls.resolvers import get_resolver
root_resolver = get_resolver()

def _join_namespace(a, b):
    return (a + ':' if a else '') + (b or '')

def _print_resolver(namespace, resolver):
    _namespace = _join_namespace(namespace, resolver.namespace)
    for ns, (prefix, res) in resolver.namespace_dict.items():
        _print_resolver(_namespace, res)
    for n, l in resolver.reverse_dict.items():
        if callable(n):
            continue
        print(_join_namespace(_namespace, n))

_print_resolver('', root_resolver)

結果
