django - Django 将所有请求定向到子应用程序而不是 mainapp

问题描述

这是我的项目的树：

├── db.sqlite3
├── kitchen_analytics
│   ├── settings.py
│   ├── static_html
│   ├── urls.py
│   └── wsgi.py
├── manage.py
├── statistics101
│   ├── admin.py
│   ├── apps.py
│   ├── computation_logic
│   │   └── dish_count.py
│   ├── migrations
│   ├── models_default.py
│   ├── models.py
│   ├── statsrouter.py
│   ├── templates
│   │   └── statistics101
│   │       └── orders_list.html
│   ├── tests.py
│   ├── urls.py
│   └── views.py
└── templates
    └── index.html

我正在尝试添加简单的 html 索引页面，这是我的 urlpatterns 配置kitchen_analytics/urls.py：

urlpatterns = [
    path('', TemplateView.as_view(template_name='index.html')),
    path('admin/', admin.site.urls),
    path('', include(statistics101.urls, namespace='statistics101')),
]

当我去http://127.0.0.1:8000/我得到模板未找到错误。Django 尝试去statistics101app 并在那里寻找 index.html。我该如何解决？

同样出于某种原因，我必须保留statistics101app 的模板，templates/statistics101而不仅仅是templates. 如何将其保存在模板中？

这是一个错误：

TemplateDoesNotExist at /
index.html
Request Method: GET
Request URL:    http://127.0.0.1:8000/
Django Version: 2.1.7
Exception Type: TemplateDoesNotExist

这是模板加载器事后分析：

Using engine django:

django.template.loaders.app_directories.Loader: /home/uname/PycharmProjects/kitchen_analytics/statistics101/templates/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/uname/PycharmProjects/kitchen_analytics/venv/lib/python3.6/site-packages/django/contrib/admin/templates/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/uname/PycharmProjects/kitchen_analytics/venv/lib/python3.6/site-packages/django/contrib/auth/templates/index.html (Source does not exist)

这是来自 settings.py 的模板设置

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

解决方案

您的模板 DIRS 设置中不存在您的顶级模板目录。你应该添加它：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        ...
    }
]
