Python django.core.exceptions.ImpropertlyConfigured错误：请求的设置已安装\u应用程序，但未配置设置

背景：

 django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

我正在从事一个由两个应用程序组成的微服务项目：

Django应用程序（管理应用程序）

和

Flask应用程序（主应用程序）

。每一个都在

Docker

容器上运行。 错误发生在我试图实现一项功能时，即每当主应用程序中喜欢某个产品时，信息都会通过

RabbitMQ

传递给管理应用程序，这样喜欢的产品也可以在其数据库中得到更新

我一直在管理员应用程序中遇到这个错误，因为管理员应用程序的数据库中没有更新like

from products.models import Product
import pika
import json
import os
import django

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "admin.settings")
django.setup()

params = pika.URLParameters(
    'amqps://mynfehiw:zXmApSaqRu8AJo3oTmJTxGzzEo8KTs6F@lionfish.rmq.cloudamqp.com/mynfehiw')


connection = pika.BlockingConnection(params)

channel = connection.channel()

channel.queue_declare(queue='admin')


def callback(ch, method, properties, body):
    print('Received in admin')
    id = json.loads(body)
    print(id)
    product = Product.objects.get(id=id)
    product.likes = product.likes + 1
    product.save()
    print('Product likes increased!')


channel.basic_consume(
    queue='admin', on_message_callback=callback, auto_ack=True)

print('Started Consuming')

channel.start_consuming()

channel.close()

Django（管理）应用程序的项目结构

它由一个应用程序产品组成

错误详细信息：

 django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

相关文件：

 django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

这是管理应用程序的

consumer.py

文件

from products.models import Product
import pika
import json
import os
import django

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "admin.settings")
django.setup()

params = pika.URLParameters(
    'amqps://mynfehiw:zXmApSaqRu8AJo3oTmJTxGzzEo8KTs6F@lionfish.rmq.cloudamqp.com/mynfehiw')


connection = pika.BlockingConnection(params)

channel = connection.channel()

channel.queue_declare(queue='admin')


def callback(ch, method, properties, body):
    print('Received in admin')
    id = json.loads(body)
    print(id)
    product = Product.objects.get(id=id)
    product.likes = product.likes + 1
    product.save()
    print('Product likes increased!')


channel.basic_consume(
    queue='admin', on_message_callback=callback, auto_ack=True)

print('Started Consuming')

channel.start_consuming()

channel.close()

已经尝试过的事情：

 django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

在阅读了StackOverflow的其他答案后，我加入了以下代码：

在

consumer.py

文件中。然而，这似乎不起作用

我使用

Docker compose up

运行了我的Docker容器，并在另一个终端上编写了这个命令

这也行不通

您能告诉我如何解决此错误吗？

在设置django后尝试导入

产品

：

导入鼠兔
导入json
导入操作系统
进口django
os.Enviro.setdefault（“DJANGO\u设置\u模块”、“管理设置”）
django.setup（）
从产品。模型导入产品
...

在python中导入模块时，会执行它们的代码：执行导入，定义类和变量，等等。Django项目文件，如

模型

通常会导入一些Django模块，这些模块在使用时会尝试读取设置。现在还没有初始化

---

因此，您需要先初始化django，然后导入模型。

您的

admin

文件夹中有

settings.py

吗？@SLDem是的，我已经在问题本身中添加了

settings.py

文件。看看这个主题@SLDem这是我访问的第一个链接。我已经尝试过这里提到的方法，甚至在我的帖子中写过一些。它们似乎不起作用。
