Question

我是DJANGO的初学者..我正在创建我的第一个模板并尝试通过get_template（）加载到我的视图中。但它显示错误“TemplateDoesNotExist at / time /”。我不知道我做错了什么。这些是我的档案。

            )

------------ ----------- views.py

from django.shortcuts import render
from django.template import Template, Context
from django.template.loader import get_template

# Create your views here.
from django.http import HttpResponse
import datetime
def current_date_time(response):
    now=datetime.datetime.now()
    t=get_template('time.html')
    time=t.render(Context({'time':now}))
    return HttpResponse(time)
def hours_ahead(response,offset):
    offset=int(offset)
    final_time=datetime.datetime.now()+ datetime.timedelta(hours=offset)
    final="<html><body>the time after %s hours will be %s</body></html>" %(offset,final_time)
    return HttpResponse(final)

---------------为time.html ------------

<html><body>It is now {{ time }}.</body></html>

正如您在official release django docs中所看到的，在版本1.8中，有关模板参数的配置方式已发生变化。

TEMPLATE_DIRS已被弃用，因此您可以将其从settings.py中删除。

相反，在TEMPLATES中，正确设置DIRS键（现在为空）。

例如：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates'), ], # check the path depending on your prj structure
        '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',
            ],
        },
    },
]

Django，无法通过TEMPLATE_DIRS加载模板
