一、django-constance配置（没用用redis，参考连接1，参考连接2（官方））

settings.py
INSTALLED_APPS = [
    'simpleui',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'constance',
    'constance.backends.database',
    'django_bootstrap5',
    'django_apscheduler',
    'SomeScheduler',
    'changeIP',
    'checkIn',
]
# django-constance配置
CONSTANCE_BACKEND = 'constance.backends.database.DatabaseBackend'


from collections import OrderedDict
CONSTANCE_CONFIG = OrderedDict([
    ('SITE_NAME', ('My Title', 'Website title')),
    ('SITE_DESCRIPTION', ('', 'Website description')),
    ('THEME', ('light-blue', 'Website theme')),
])


from SomeScheduler import signals  # 试了下貌似把signals的内容直接写在settings下好像不生效。。

二、signals.py设置（signal详细使用方法可以查询：参考连接1，参考连接2（刘江））

from django.dispatch import receiver
from constance.signals import config_updated
from constance import config




@receiver(config_updated)
def constance_updated(sender, key, old_value, new_value, **kwargs):


    print(sender, key, old_value, new_value)
    if key == 'SITE_NAME':
        # 写你想要的内容
        print("XX已变更")

如果用在了debug上，记得把setting.py里的debug注销掉，这样默认django保存或重启时，debug是关闭的。
