我正在尝试在我的应用中使用此应用https://github.com/benliles/django-chance。我的Django版本是1.9。我收到以下错误：

您使用的django-chance应用程序在几年内未更新，似乎不支持Django 1.9。您可以使用其他应用程序，也可以尝试更新它以使用Django 1.9。
这部分追溯显示它在signals.py中导入__init__.py， File "/home/bewithaman/Projects/Event-Management-System/chance/__init__.py", line 1, in <module>
from chance import signals
File "/home/bewithaman/Projects/Event-Management-System/chance/signals.py", line 7, in <module>
from chance.models import Registration
尝试在加载应用之前导入模型。
chance/__init__.py从from chance import signals
文件中删除此行
change/apps.py然后创建一个ready()文件，并定义一个应用程序配置类，用于导入from django.apps import AppConfig
class ChanceConfig(AppConfig):
def ready(self):
from . import signals
方法中的信号。
INSTALLED_APPS最后，更新您的INSTALLED_APPS = [
...
'chance.apps.ChanceConfig',
...
]
设置以使用您的配置。
