ImproperlyConfigured：請求設定INSTALLED_APPS，但未配置設定。Heroku

2022-02-20 01:00:24 前端設計

我正在嘗試在 Heroku 上設定我的 Django 專案。這是我第一次這樣做。

部署成功但打開視圖時我收到此訊息：ImproperlyConfigured: Requested setting INSTALLED_APPS，但未配置設定。（下面的完整追溯）。

我正在使用 Heroku Postgres 和 Heroku Redis 附加組件。

我究竟做錯了什么？

Procfile

release: python manage.py migrate
web: daphne test_cs.asgi:application --port $PORT --bind 0.0.0.0 -v2
worker: python manage.py runworker channels --settings=test_cs.settings -v2

runtime.txt

python-3.10.2

asgi.py

import os

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter

from django.core.asgi import get_asgi_application

import main.routing


os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'test_cs.settings')

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    "websocket": AuthMiddlewareStack(
        URLRouter(
            main.routing.websocket_urlpatterns
        )
    )
})

uj5u.com熱心網友回復：

我能夠通過更改os.environ.setdefault匯入前的位置來解決問題。顯然順序很重要。我在這里找到了解決方案

updated asgi.py
import os
import django

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'test_cs.settings')
django.setup()

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter

from django.core.asgi import get_asgi_application

import main.routing


django_asgi_app = get_asgi_application()

application = ProtocolTypeRouter({
