Django-apps.py 无法识别

Question

Django 版本 1.11.7

尝试为 post_save 执行执行 signals.py在 app_1 但似乎连我的 apps.py 都没有执行。

apps.py

from django.apps import AppConfig

class AppOneConfig(AppConfig):
    name = 'app_1'

    def ready(self):
        print("test")
        from . import signals

__ 初始化 __.py

default_app_config = "apps.app_1.apps.AppOneConfig"

这是我遇到的错误

django.core.exceptions.ImproperlyConfigured: Cannot import 'app_1'. Check that 'apps.app_1.apps.AppOneConfig.name' is correct.

settings.py、INSTALLED_APPS

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'apps.app_1'
]

Answer 1

apps.py：

from django.apps import AppConfig

class AppOneConfig(AppConfig):
            ⬇⬇⬇
    name = 'apps.app_1'

    def ready(self):
        print("test")
        from . import signals

settings.py：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'apps.app_1.apps.AppOneConfig' ⬅⬅⬅⬅⬅
