Django的邮递员不工作

Question

我试图Django-postman为用户实现用户间的消息传递系统。

我克隆回购，在我做这个settings.py和URLs.py文件太：

在URLs.py主文件中，我包括：

 re_path(r'^messages/', include('postman.urls', namespace='postman')),

在Settings.py文件中，我包括：

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'postman',

    'account',

    'landingpage',

]

POSTMAN_I18N_URLS = True  # default is False

POSTMAN_DISALLOW_ANONYMOUS = True  # default is False

POSTMAN_DISALLOW_MULTIRECIPIENTS = True  # default is False

POSTMAN_DISALLOW_COPIES_ON_REPLY = True  # default is False

POSTMAN_DISABLE_USER_EMAILING = True  # default is False

POSTMAN_FROM_EMAIL = '[e-mail]'  # default is DEFAULT_FROM_EMAIL

#POSTMAN_PARAMS_EMAIL = get_params_email  # default is None

POSTMAN_AUTO_MODERATE_AS = True  # default is None

POSTMAN_SHOW_USER_AS = 'get_full_name'  # default is None

POSTMAN_NAME_USER_AS = 'last_name'  # default is None

POSTMAN_QUICKREPLY_QUOTE_BODY = True  # default is False

POSTMAN_NOTIFIER_APP = None  # default is 'notification'

POSTMAN_MAILER_APP = None  # default is 'mailer'

问题是，每当我在浏览器中运行127.0.0.1:8000/messages/write时，该网站都是空白的。django管理员显示消息框，但url返回空白。我在这里做错了什么。谢谢
