带有 CherryPy 的 Django - ModuleNotFound 错误
Django with CherryPy - ModuleNotFound errors
我发现 a gist 可以让我将 CherryPy 网络服务器集成到我的程序中，并通过该 CherryPy 网络服务器 运行 一个 Django 项目。但是我在使它正常工作时遇到了一些困难。
这是我代码中的 Class 要点，基本没有变化
class ClientThread(object):
HOST = "127.0.0.1"
PORT = int("3852")
DIR = "/home/user/project/"
STATIC_ROOT = DIR + '/clientFiles/static/'
def mount_static(self, url, root):
"""
:param url: Relative url
:param root: Path to static files root
"""
config = {
'tools.staticdir.on': True,
'tools.staticdir.dir': root,
'tools.expires.on': True,
'tools.expires.secs': 86400
}
cherrypy.tree.mount(None, url, {'/': config})
def run(self):
cherrypy.config.update({
'server.socket_host': self.HOST,
'server.socket_port': self.PORT,
'engine.autoreload_on': False,
'log.screen': True
})
self.mount_static(settings.STATIC_URL, self.STATIC_ROOT)
cherrypy.tree.graft(WSGIHandler())
cherrypy.engine.start()
print("[Info]: Client started. Use http://{0}:{1} to access the WebApp.".format(self.HOST,self.PORT))
cherrypy.engine.block()
def init(self):
print("[Info]: Starting Client WebApp...")
cThread = Thread(target=self.run)
cThread.start()
整个class是通过ClientThread().init()
发起的
我的应用程序顶部的要点的前几行（按顺序）：
import os
from threading import Timer
os.environ["DJANGO_SETTINGS_MODULE"] = "clientFiles.settings"
import django
django.setup()
import cherrypy
from django.conf import settings
from django.core.handlers.wsgi import WSGIHandler
我的项目布局如下：
.
├── clientFiles
│ ├── clientFiles

├── main.py
我在 django-admin startproject clientFiles.
的根目录中启动了我的 Django 项目
当我尝试 运行 我的程序时，我得到：
Traceback (most recent call last):

ModuleNotFoundError: No module named 'clientFiles.settings'
看起来像是模块加载问题，对吧？
所以我尝试将 os.environ["DJANGO_SETTINGS_MODULE"] = "clientFiles.settings" 更改为 os.environ["DJANGO_SETTINGS_MODULE"] = "clientFiles.clientFiles.settings" 因为我的 Django url 在 clientFiles/clientFiles
这样做之后，我的应用程序启动表明 CherryPy 启动没有问题：

好的，所以目录结构可能有问题....
我将 clientFiles/clientFiles 的内容移动到 clientFiles 中，所以我有这个：
.
├── clientFiles
│ ├── asgi.py
│ ├── __init__.py
│ ├── manage.py
│ ├── __pycache__
│ │ ├── __init__.cpython-37.pyc
│ │ └── settings.cpython-37.pyc
│ ├── settings.py
│ ├── static
│ ├── urls.py
│ └── wsgi.py
├── main.py
啊哈！启动成功。我看到欢迎使用 Django 页面。
但是，当我尝试创建一个用于登录或其他用途的新应用时...
python3 manage.py startapp login
在我现在的 clientFiles 目录中
.
├── asgi.py
├── __init__.py
├── login
│ ├── admin.py
│ ├── apps.py

│ ├── settings.cpython-37.pyc
│ └── urls.cpython-37.pyc
├── settings.py
├── static
├── urls.py
└── wsgi.py
只需按照此处的教程操作即可：https://docs.djangoproject.com/en/3.1/intro/tutorial01/
我创建了视图，在登录应用程序中创建了 urls.py，并将以下内容插入 clientFiles/urls.py:
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('login/', include('login.urls')),
path('admin/', admin.site.urls),
]
运行 程序...启动正常。但是当我尝试浏览 http://127.0.0.1:3852 上的任何地方时，我现在得到

这就是我被困的地方。我试过左右修改路径、目录结构、为新目录添加 CherryPy 的额外安装……我不知所措。
如果您有任何想法，我们将不胜感激...或者是否有其他方法可以将网络服务器集成到我的应用程序中，该应用程序能够通过 django 或 Laravel 提供动态和静态内容？
