TemplateDoesNotExist 位于 /base.html

朋友们。 我尝试通过 Jaiswal、Sanjeev 所著的《学习 Django Web 开发》一书中的项目示例来重复。

运行服务器我得到这样的异常：TemplateDoesNotExist at /base.html

TemplateDoesNotExist at /
base.html

模板加载器事后分析

Django tried loading these templates, in this order:

    Using loader django.template.loaders.filesystem.Loader:
    Using loader django.template.loaders.app_directories.Loader:
        C:\Python34\lib\site-packages\django\contrib\admin\templates\base.html (File does not exist)
        C:\Python34\lib\site-packages\django\contrib\auth\templates\base.html (File does not exist)

我的settings.py文件：

import os

SETTINGS_PATH = os.path.dirname(__file__)
PROJECT_PATH = os.path.join(SETTINGS_PATH, os.pardir)
PROJECT_PATH = os.path.abspath(PROJECT_PATH)
TEMPLATE_PATH = os.path.join(PROJECT_PATH, "templates")

SECRET_KEY = 'khcr3h6u+ghi+rtb+g_(mvgq!mtn9u4&%=hu20vt2*u(p8-kde'

ROOT_URLCONF = 'mytweets.urls'

TEMPLATES = [
    {

                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

WSGI_APPLICATION = 'mytweets.wsgi.application'

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(PROJECT_PATH, 'db.sqlite3'),
    }
}

LANGUAGE_CODE = 'en-us'

USE_I18N = True

USE_TZ = True

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(
        os.path.dirname(__file__),
        'static',
    ),
)

TEMPLATE_DIRS = (
    TEMPLATE_PATH,
)

TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',
)

我也尝试以这种方式更改settings.py：

更改设置.py：

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATE_PATH = os.path.join(BASE_DIR, "templates")

    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'tweets',
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',

    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
)

ROOT_URLCONF = 'mytweets.urls'

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',
            ],
        },
    },
]

WSGI_APPLICATION = 'mytweets.wsgi.application'

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = True

USE_TZ = True


STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(
        os.path.dirname(__file__),
        'static',
    ),
)

我的项目结构：

视图.py:

from django.views.generic import View
from django.shortcuts import render


class Index(View):
    def get(self, request):
        params = {}
        params['name'] = 'Django'
        return render(request, 'base.html', params)

urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin
from tweets.views import Index
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^$', Index.as_view()),
    url(r'^admin/', include(admin.site.urls)),
)

请给出建议，我应该更改什么才能获得渲染页面？

我对你正在使用的这本书不熟悉，所以我无法据此给你任何建议。如果这本书是针对 Django 1.7 的，你会发现使用 Django 1.7 而不是 Django 1.8 更容易，至少当你刚开始使用 Django 时是这样。

如果您想坚持使用 Django 1.8，以下是修复您当前看到的错误的方法：

Your settings.py文件混合了旧模板设置，例如TEMPLATE_DIRS and TEMPLATE_LOADERS(Django TEMPLATES（Django 1.8+）。

首先，删除旧的设置TEMPLATE_DIRS and TEMPLATE_LOADERS.

其次，看起来好像DIRS你的内容不正确TEMPLATES环境。

Define BASE_DIR，应包含在settings.py默认情况下，当你运行./manage.py startproject

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

然后改变TEMPLATES to

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