TemplateDoesNotExist: personal/home.html .

Question

我试图访问home.html，相对路径类似于这个hub/templates/hub/home.html。

但是，我想访问所有的模板文件夹，我正试图通过settings.py中提供的代码来实现这一点。它看起来与其他人的帖子不同(没有'os‘选项)

这是我的settings.py

   from pathlib import Path


    # Build paths inside the project like this: BASE_DIR / 'subdir'.
    BASE_DIR = Path(__file__).resolve().parent.parent
    # SECURITY WARNING: don't run with debug turned on in production!


    DEBUG = True

ALLOWED_HOSTS = []
# My apps
'hub',

# Application definition

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

MIDDLEWARE = [

ROOT_URLCONF = 'mysite.urls'

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

WSGI_APPLICATION = 'mysite.wsgi.application'


# Database

DATABASES = {
    'default': {

# Default primary key field type

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

这是我的views.py

from django.shortcuts import render
  


def home_screen_view(request):

return render(request, "hub/home.html", {})

谁能告诉我怎么解决这个问题吗？

Answer 1

您需要将hub添加到INSTALLED_APPS，因此将'hub.apps.HubConfig',添加到INSTALLED_APPS。

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'hub.apps.HubConfig',
]

注意：

在您的home_screen_view中，返回应该在函数下面，因此需要添加制表符空间。

def home_screen_view(request):
    return render(request, "hub/home.html", {})
