Question

朋友。我试着通过Jaiswal，Sanjeev的书中的项目示例重复：“学习Django Web开发”。

运行服务器我得到了这样的例外：/ base.html上的TemplateDoesNotExist

模板加载器postmortem

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")

    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：

更改了settings.py：

)

我的项目结构：

My project structure:

views.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)),
)

请提出建议，我应该更改什么才能获得渲染页面？

Answer 1

我对你正在使用的书不太熟悉，所以我不能基于此给你任何建议。如果这本书适用于Django 1.7，你会发现使用Django 1.7而不是Django 1.8更容易，至少当你开始使用Django时。

如果你想坚持使用Django 1.8，这里是如何解决你目前看到的错误：

您的settings.py文件混合了旧的模板设置，例如TEMPLATE_DIRS和TEMPLATE_LOADERS（Django＆lt; = 1.7），以及TEMPLATES下的新设置（Django 1.8+）。

首先，删除旧设置TEMPLATE_DIRS和TEMPLATE_LOADERS。

其次，DIRS设置中的TEMPLATES似乎不正确。

定义BASE_DIR，默认情况下，settings.py运行./manage.py startproject

时应包含在

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

中

TEMPLATES

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

$input = [
  '2015-07-10' => 94,
  '2015-07-07' => 20,
  '2015-07-13' => 6,
  '2015-07-09' => 42,
  '2015-07-08' => 48
];

// Dates range
$StartDate = '07-07-2015';
$EndDate = '14-07-2015';

// Make array date =>0
$i = strtotime($StartDate);
$iEnd = strtotime($EndDate);
$dates = [];

While ($i <= $iEnd) {
   $dates[date('Y-m-d', $i)] = 0;;
   $i = strtotime('+1day', $i);  
  }
// Set existing data
$res = array_replace($dates, $input);

print_r($res);

Answer 2

我也遇到了同样的问题，我试图通过将HTML模板{% extends "base.html" %}的快捷方式添加到{% extends "foldername/template/base.html" %}来解决该问题。

之后，我将添加到每个项目模板文件夹中的“ base.html”文件。它对我有用。

Answer 3

在已安装的应用程序中，添加mytweets而不是tweets。

Answer 4

我确实遇到了这个问题，在 my_project/templates/base.html 中找不到 base.html。

我修复了它在调用它的应用程序之后移动目录模板的问题（在越野车之前）

--my_project
 --templates
 --app_a
(after fixed)
--my_project
 --app_a
 --templates

Answer 5

在settings.py

的DIR []中设置模板路径

 TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [**'C:\\Python27\\Lib\\site-packages\\django\\contrib\\admin\\templates\\admin'**],
        'APP_DIRS':True,
        'OPTIONS': {

/ base.html上的TemplateDoesNotExist
