模板不存在

Question

我是Django的新手.我在我的项目中创建了一个名为templates的文件夹,并在其中创建了"base.html",它工作正常.但是当我在模板欢迎中创建新文件夹然后"home.html"并且我在views.py文件中写了一些代码行

from django.shortcuts import render_to_response

def hello(request):
    return render_to_response('welcome/home.html')

和settings.py包括

# Django settings for Telecom project.

我该如何解决？

Answer 1

对于Django 1.8或更高版本,您必须在列表的DIRS键中添加模板路径TEMPLATES作为字符串列表.

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['Secondjango/Secondjango/templates/welcome'],        #<<<<<<<<Here
        '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',
            ],
        },
    },
]

Answer 2

由于模板目录不正确,可能会出现此错误尝试进行一些更改,settings.py如下所示

import os.path
Temp_Path = os.path.realpath('.')
...
STATIC_ROOT = ''    
# URL prefix for static files.
# Example: "http://example.com/static/", "http://static.example.com/"
STATIC_URL = '/static/'
...
TEMPLATE_DIRS = (
    Temp_Path +"/template"
)

然后将所有模板放在模板文件夹和css/javascript文件中的静态文件夹中,该文件夹位于应用程序文件夹中.希望这能解决你的问题.

我的建议不要将模板文件夹放在应用程序文件夹中

Django将选择它找到的第一个名称匹配的模板,如果你在不同的应用程序中有一个同名的模板,Django将无法区分它们.我们需要能够将Django指向正确的,并且确保这一点的最简单方法是通过命名它们.也就是说,将这些模板放在为应用程序本身命名的另一个目录中.

Answer 3

尝试这个：

在您的settings.py文件中替换

 
TEMPLATE_DIRS = (       
                  os.path.join(PROJECT_DIR, 'templates'),

)
 

与

 
TEMPLATE_DIRS = (       
                  os.path.join(PROJECT_DIR, 'templates'),
                  os.path.join(PROJECT_DIR, 'templates/welcome')

)
 

然后，在您的代码中，只需调用render_to_response（“ home.html”）即可

解决您的问题。
