Django将url映射到视图

Question

ModuleNotFoundError:没有名为"操场/urls"的模块我正在经历莫什·哈梅达尼的终极django系列，我遇到了一个问题。我完全按照他的做法做了，但这对我不起作用。以下是我的urls.py和安装的应用程序。

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.messages',
'django.contrib.staticfiles',
'playground'

]

游乐场/uls.py

from django.urls import path
from . import views
#URLConf
urlpatterns = [
path('hello/', views.say_hello)
]

店面/uls.py

"""storefront URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/4.1/topics/http/urls/
Examples:
Function views
1. Add an import:  from my_app import views
2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
1. Add an import:  from other_app.views import Home
2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('playground/', include('playground/urls'))
]

Answer 1

可能使用include('appname.ulls'(

更改

path('playground/', include('playground/urls'))

至

path('playground/', include('playground.urls'))

Answer 2

尝试：

path('playground/', include('playground.urls'))

Insteed of：

path('playground/', include('playground/urls'))

你可以在Django教程上查看该部分

希望对你有所帮助！

Answer 3

如果你发布终端给你的东西，这有时也很有帮助，据我所知，模型不存在，

尝试python管理.py makemigrations
