在哪里放置django信号接收码，将它们传播到多个文件？ [英] where to put django signal receiver code, spread them over multiple files?

问题描述

然而，信号接收器不断增长，我想将它们分隔成多个文件。

我没有看到关于在哪里放置信号接收器代码的讨论。

（让我怀疑我不应该使许多信号接收器可能吗？）

解决方案

查看文档：

https://docs.djangoproject.com/en/1.8/topics/signals/#connecting-receiver-功能

这是常见的将它们放在一个单独的 signals.py 文件中，也许是项目中的每个模块一个，但是您需要确保这些文件被导入，以便您的信号接收器被注册。

如上面的文档所述，Django 1.7+现在有这种情况下的 AppConfig.ready 机制

这里有一个很好的解释：

http://chriskief.com/2014/02/28/django-1-7-signals-appconfig/

（作为您可能会做的一个例子）

基本上：

 ＃myapp / __ init__.py 
 default_app_config ='myapp.apps.MyAppConfig'
  

和

 ＃myapp / apps.py 
 from django.apps import AppConfig 
 
 class MyAppConfig（AppConfig）：
 
 name ='myapp'
 verbose_name ='我的应用'
 
 def ready（self）：
 
＃import signal handlers 
 import myapp .signals.handlers 
  

I've put my signal receiver code in the respective model file.

However, signal receivers keep growing and I'd like to separate them over multiple files.

I haven't seen discussion on where to put signal receiver codes.

(makes me suspect that I'm not supposed to make many signal receivers maybe?)

解决方案

See the docs:
https://docs.djangoproject.com/en/1.8/topics/signals/#connecting-receiver-functions

it's common to put them in a separate signals.py file, perhaps one per module in your project, but you need to ensure that these files get imported so that your signal receivers get registered.

as detailed in the docs above, Django 1.7+ now has the AppConfig.ready mechanism for this kind of case

There's a good explanation here:
http://chriskief.com/2014/02/28/django-1-7-signals-appconfig/

(as an example of what you might do)

basically:

# myapp/__init__.py
default_app_config = 'myapp.apps.MyAppConfig'

and

# myapp/apps.py
from django.apps import AppConfig

class MyAppConfig(AppConfig):

    name = 'myapp'
    verbose_name = 'My App'

    def ready(self):

        # import signal handlers
        import myapp.signals.handlers
