django - TemplateDoesNotExist 在/django

Question

出错了

views.py:

def index(request):
        user = request.user
        return render(request, 'main_app/index.html',{'user': user})

试过这个:

'DIRS': [os.path.join(BASE_DIR, 'templates')],

但没有帮助

指令:

文件结构:

Django 2.0

设置.py

INSTALLED_APPS = [
# 'main_app.apps.MainAppConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'main_app'

]

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

您应该将模板从 main_app/templates 移动到嵌套的子文件夹 main_app/templates/main_app。

例如，在 django tutorial 中对此进行了解释
