django - 用一个接收器合并多个 post_save 信号

Question

所以我阅读了 Django 源代码(1.5 后)，您现在可以将多个信号注册到接收器函数:

def receiver(signal, **kwargs):
    """
    A decorator for connecting receivers to signals. Used by passing in the
    signal (or list of signals) and keyword arguments to connect::

        @receiver(post_save, sender=MyModel)
        def signal_receiver(sender, **kwargs):
            ...

        @receiver([post_save, post_delete], sender=MyModel)
        def signals_receiver(sender, **kwargs):
            ...

    """
    ... implementation code...

但是，我想将来自不同发件人 的多个post_save 信号注册到同一个函数。现在，我只是打电话

post_save.connect(fn_name, model_name)

对于我拥有的每个模型。有没有更好的方法使用新的 Django 1.5 @receiver 装饰器功能来做到这一点？

Answer 1

您可以使用 @receiver decorator 来做到这一点:

from django.dispatch import receiver

@receiver(post_save, sender=Model1)
@receiver(post_save, sender=Model2)
@receiver(post_save, sender=Model3)
def my_signal_handle(sender , **kwargs)
    # some code here
