Python Django信号接收器不'；尽管在ready（）方法中已连接，但无法工作

我是Django的新手，也许我的问题有一个简单的答案，但我陷入了僵局。 我的信号代码存在于

signals.py

，我使用

@receiver

。根据文档，我在

apps.py

中导入了ready（）中的信号子模块。但是它不起作用，有人能帮我吗

注意：如果我在models.py中写入信号代码，一切都会正常工作

代码：

signal.py

from django.db.models.signals import post_delete
from django.dispatch import receiver
import os
from .models import ProductImage

def delete_image_from_storage(path):
  if os.path.isfile(path):
     print(path)
     os.remove(path)


@receiver(post_delete, sender=ProductImage)
def post_delete_image(sender, instance, **kawargs):
  if instance.photo:
      print(instance.photo.path)
      delete_image_from_storage(instance.photo.path)

from django.apps import AppConfig


class ProductsConfig(AppConfig):
  name = 'products'

  def ready():
      import products.signals

INSTALLED_APPS = [
    ...,
    'products',
    ...,
]

apps.py

from django.db.models.signals import post_delete
from django.dispatch import receiver
import os
from .models import ProductImage

def delete_image_from_storage(path):
  if os.path.isfile(path):
     print(path)
     os.remove(path)


@receiver(post_delete, sender=ProductImage)
def post_delete_image(sender, instance, **kawargs):
  if instance.photo:
      print(instance.photo.path)
      delete_image_from_storage(instance.photo.path)

from django.apps import AppConfig


class ProductsConfig(AppConfig):
  name = 'products'

  def ready():
      import products.signals

INSTALLED_APPS = [
    ...,
    'products',
    ...,
]

settings.py

from django.db.models.signals import post_delete
from django.dispatch import receiver
import os
from .models import ProductImage

def delete_image_from_storage(path):
  if os.path.isfile(path):
     print(path)
     os.remove(path)


@receiver(post_delete, sender=ProductImage)
def post_delete_image(sender, instance, **kawargs):
  if instance.photo:
      print(instance.photo.path)
      delete_image_from_storage(instance.photo.path)

from django.apps import AppConfig


class ProductsConfig(AppConfig):
  name = 'products'

  def ready():
      import products.signals

INSTALLED_APPS = [
    ...,
    'products',
    ...,
]

，您需要在

INSTALLED\u APPS

ie中明确注册appconfig：

INSTALLED_APPS = [
    ...,
    'products.apps.ProductConfig',
    ...,
]

或者在

products/\uuuuu init\uuuuuuuuuuuupy

中将其声明为

default\u app\u config

：

# products/__init__.py
default_app_config = "products.apps.ProductConfig"

谢谢！对不起，我没注意！我以为在

已安装的应用程序中注册我的应用程序名就足够了+我忘了在
就绪（）中声明
self
