Django带有CherryPy ModuleNotFound错误

Question

我发现a gist可以让我将CherryPy Web服务器集成到我的程序中，并通过该CherryPy Web服务器运行Django项目。然而，我在让它正常工作方面遇到了一些困难

这是我的代码中的类，基本上没有变化

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()

整个类是通过ClientThread().init()启动的

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

我的项目是这样安排的：

.
├── clientFiles
│   ├── clientFiles
│   │   ├── asgi.py
│   │   ├── __init__.py
│   │   ├── __pycache__
│   │   │   ├── __init__.cpython-37.pyc
│   │   │   └── settings.cpython-37.pyc
│   │   ├── settings.py
│   │   ├── urls.py
│   │   └── wsgi.py
│   ├── __init__.py
│   ├── manage.py
│   ├── __pycache__
│   │   └── __init__.cpython-37.pyc
│   └── static
├── main.py

我用django-admin startproject clientFiles在根目录中启动了Django项目

当我尝试运行我的程序时，我得到：

Traceback (most recent call last):
  File "main.py", line 26, in <module>
    django.setup()
  File "/usr/local/lib/python3.7/dist-packages/django/__init__.py", line 19, in setup

  File "/usr/local/lib/python3.7/dist-packages/django/conf/__init__.py", line 83, in __getattr__
self._setup(name)
  File "/usr/local/lib/python3.7/dist-packages/django/conf/__init__.py", line 70, in _setup
self._wrapped = Settings(settings_module)
  File "/usr/local/lib/python3.7/dist-packages/django/conf/__init__.py", line 177, in __init__
mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/usr/lib/python3.7/importlib/__init__.py", line 127, in import_module
return _bootstrap._gcd_import(name[level:], package, level)
  File "<frozen importlib._bootstrap>", line 1006, in _gcd_import
  File "<frozen importlib._bootstrap>", line 983, in _find_and_load
  File "<frozen importlib._bootstrap>", line 965, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'clientFiles.settings'

这似乎是一个模块加载问题，对吗

因此，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位于clientFiles/clientFiles中

完成此操作后，我的应用程序启动指示CherryPy启动时没有问题：

[24/Dec/2020:04:37:14] ENGINE Bus STARTING
[24/Dec/2020:04:37:14] ENGINE Started monitor thread 'Autoreloader'.

[24/Dec/2020:04:37:14] ENGINE Bus STARTED
[Info]: Client started. Use http://127.0.0.1:3852 to access the WebApp.

但是，当我试图访问位于http://127.0.0.1:3852的站点时，我得到：

在控制台中，我得到：

ModuleNotFoundError: No module named 'clientFiles.urls'

好的，也许是目录结构的问题

我将clientFiles/clientFiles的内容移动到clientFiles中，这样我就有了：

.
├── 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！创业成功。我看到了欢迎来到Django页面

但是，当我尝试创建一个新的应用程序来登录或做其他事情时

python3 manage.py startapp login

在clientFiles目录中，我现在有

.
├── asgi.py
├── __init__.py
├── login
│   ├── admin.py
│   ├── apps.py
│   ├── __init__.py
│   ├── migrations
│   │   └── __init__.py
│   ├── models.py
│   ├── tests.py
│   └── views.py
├── manage.py
├── __pycache__
│   ├── __init__.cpython-37.pyc
│   ├── settings.cpython-37.pyc
│   └── urls.cpython-37.pyc
├── settings.py
├── static
├── urls.py
└── wsgi.py

只需按照这里的教程：https://docs.djangoproject.com/en/3.1/intro/tutorial01/

我已经创建了视图，在登录应用程序中创建了urls.py，并将以下内容插入到clientFiles/urls.py中：

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…启动良好。但当我试图浏览我的http://127.0.0.1:3852上的任何地方时，我现在得到了

ModuleNotFoundError at /

No module named 'login'

Request Method:     GET
Request URL:    http://127.0.0.1:3852/

Server time:    Thu, 24 Dec 2020 04:55:22 +0000

这就是我被困的地方。我尝试过修改左右路径，目录结构，为新目录添加额外的CherryPy挂载…我不知所措

如果您有任何想法，我将不胜感激……或者如果我有一种不同的方式可以将Web服务器集成到我的应用程序中，该应用程序能够提供动态&；通过django或Laravel的静态内容

Answer 1

这很容易解决。我只是将我的应用程序的根重新创建到一个Django项目中，然后将我的main.py复制到该项目中。完成了
