如何使用公共函数处理多个模型发出的Django信号

我想编写一个通用函数来处理Django为多个模型发出的post_save信号

型号.py

Class FirstModel(models.Model):
    pass

Class AnotherModel(models.Model):
    pass

Class YetAnotherModel(models.Model):
    pass

@receiver(post_save, sender=FirstModel)
def first_model_post_save_handler(sender, **kwargs):
    pass

@receiver(post_save, sender=AnotherModel)
def another_model_post_save_handler(sender, **kwargs):
    pass

MODELS_TO_BE_POST_SAVE_HANDLED = ['FirstModel', 'AnotherModel']

@receiver(post_save, sender=MODELS_TO_BE_POST_SAVE_HANDLED)
def first_model_post_save_handler(sender, **kwargs):
    pass

对于我的models.py中的一些模型（FirstModel，AnotherModel），我需要编写一个函数，可以在保存后执行一些常见操作

好的，我可以编写两个处理函数来接收发出的信号并执行公共操作

信号.py

Class FirstModel(models.Model):
    pass

Class AnotherModel(models.Model):
    pass

Class YetAnotherModel(models.Model):
    pass

@receiver(post_save, sender=FirstModel)
def first_model_post_save_handler(sender, **kwargs):
    pass

@receiver(post_save, sender=AnotherModel)
def another_model_post_save_handler(sender, **kwargs):
    pass

MODELS_TO_BE_POST_SAVE_HANDLED = ['FirstModel', 'AnotherModel']

@receiver(post_save, sender=MODELS_TO_BE_POST_SAVE_HANDLED)
def first_model_post_save_handler(sender, **kwargs):
    pass

然而，我有兴趣知道任何更好的解决方案，使它像一个配置

配置.py

Class FirstModel(models.Model):
    pass

Class AnotherModel(models.Model):
    pass

Class YetAnotherModel(models.Model):
    pass

@receiver(post_save, sender=FirstModel)
def first_model_post_save_handler(sender, **kwargs):
    pass

@receiver(post_save, sender=AnotherModel)
def another_model_post_save_handler(sender, **kwargs):
    pass

MODELS_TO_BE_POST_SAVE_HANDLED = ['FirstModel', 'AnotherModel']

@receiver(post_save, sender=MODELS_TO_BE_POST_SAVE_HANDLED)
def first_model_post_save_handler(sender, **kwargs):
    pass

信号.py

Class FirstModel(models.Model):
    pass

Class AnotherModel(models.Model):
    pass

Class YetAnotherModel(models.Model):
    pass

@receiver(post_save, sender=FirstModel)
def first_model_post_save_handler(sender, **kwargs):
    pass

@receiver(post_save, sender=AnotherModel)
def another_model_post_save_handler(sender, **kwargs):
    pass

MODELS_TO_BE_POST_SAVE_HANDLED = ['FirstModel', 'AnotherModel']

@receiver(post_save, sender=MODELS_TO_BE_POST_SAVE_HANDLED)
def first_model_post_save_handler(sender, **kwargs):
    pass

提前感谢：）

您可以使用

post\u save.connect（）

而不是

@receiver（post\u save…）

或者作为

post\u save.connect（model\u post\u save\u处理程序，sender=FirstModel）
post\u save.connect（model\u post\u save\u处理程序，sender=SecondModel）

或作为

对于要处理的模型中的模型：
post\u save.connect（模型\u post\u save\u处理程序，发送方=模型）

还可以看一看，这是值得一读的
