python - django.contrib.auth 中的哪个函数创建默认模型权限？

Question

在 django 文档中它说:

These permissions will be created when you run manage.py migrate; the first time you run migrate after adding django.contrib.auth to INSTALLED_APPS, the default permissions will be created for all previously-installed models, as well as for any new models being installed at that time. Afterward, it will create default permissions for new models each time you run manage.py migrate (the function that creates permissions is connected to the post_migrate signal)

它表示创建这些权限的函数与 post_migration 信号有关。我想知道这是哪个函数，因为我需要在代码中以编程方式设置默认权限。

迁移后信号从 here 发出

class AuthConfig(AppConfig):
     name = 'django.contrib.auth'
     verbose_name = _("Authentication and Authorization")

     def ready(self):
         post_migrate.connect(
             create_permissions,
            dispatch_uid="django.contrib.auth.management.create_permissions"
        )
    ...

权限是从 here 创建的
