Django为不同应用程序发出信号

我需要为我的项目的每个应用程序有单独的信号.但在其中一个应用程序中保存模型后，所有应用程序都会触发信号，所以我复制了信号中的信息.为Django项目的不同应用程序设置信号的正确方式是什么？

我的app1的signals.py:

# -*- coding: utf-8 -*-
import logging

from django.db.models.signals import post_save
from django.dispatch import receiver

from .models import *


@receiver(post_save)
def log_app1_updated_added_event(sender, **kwargs):
    '''Writes information about newly added or updated objects of app1 into log file'''

    logger = logging.getLogger(__name__)

    app1_object = kwargs['instance']
    
    if kwargs['created']:
        logger.info(f'added {app1_object }')
    else:
        logger.info(f'updated {app1_object }')

我的应用程序2的Signals.py:

# -*- coding: utf-8 -*-
import logging

from django.db.models.signals import post_save
from django.dispatch import receiver

from .models import *


@receiver(post_save)
def log_app2_updated_added_event(sender, **kwargs):
    '''Writes information about newly added or updated objects of app2 into log file'''

    logger = logging.getLogger(__name__)

    app2_object = kwargs['instance']
    
    if kwargs['created']:
        logger.info(f'added {app2_object }')
    else:
        logger.info(f'updated {app2_object }')

apps.py of my app1:

from django.apps import AppConfig


class App1Config(AppConfig):
    name = 'App1'

    def ready(self):
        from app1 import signals

我的app2的apps.py:

from django.apps import AppConfig


class App1Config(AppConfig):
    name = 'App2'

    def ready(self):
        from app2 import signals

下面是我的项目settings.py中的记录器部分

'loggers': {
        'django': {
            'handlers': ['console',],
            'propagate': False,
            'level': 'INFO',
        },
        'app1.signals': {
            'handlers': ['console', 'file'],
            'level': 'INFO',
        },
        'app2.signals': {
            'handlers': ['console', 'file'],
            'level': 'INFO',
        },
     }
