Django未加载模板，但模板位置出错

Question

Okay, I am using django 1.8. I am trying to get templates working with render in my views. Here's my layout:

├── db.sqlite3
├── django_classr_test
│   ├── __init__.py
│   ├── __init__.pyc
│   ├── __pycache__
│   │   ├── __init__.cpython-34.pyc
│   │   ├── settings.cpython-34.pyc
│   │   ├── urls.cpython-34.pyc
│   │   └── wsgi.cpython-34.pyc
│   ├── settings.py
│   ├── settings.pyc
│   ├── urls.py
│   ├── urls.pyc
│   ├── wsgi.py
│   └── wsgi.pyc
├── manage.py
├── static_pages
│   ├── admin.py
│   ├── __init__.py
│   ├── __init__.pyc
│   ├── migrations
│   │   ├── __init__.py
│   │   └── __pycache__
│   │       └── __init__.cpython-34.pyc
│   ├── models.py
│   ├── __pycache__
│   │   ├── admin.cpython-34.pyc
│   │   ├── __init__.cpython-34.pyc
│   │   ├── models.cpython-34.pyc
│   │   ├── urls.cpython-34.pyc
│   │   └── views.cpython-34.pyc
│   ├── templates
│   │   └── static_pages
│   │       ├── contact.html
│   │       ├── index.html
│   │       └── legal.html
│   ├── tests.py
│   ├── urls.py
│   ├── urls.pyc
│   ├── views.py
│   └── views.pyc

So I have a templates folder inside my static_pages app folder. So, I should just be able to say render(request, 'static_pages/index.html') , right? Here's my view:

from django.shortcuts import render

from django.http import HttpResponse
def index(request):
    return render(request, 'static_pages/templates/static_pages/index.html')

And yet, it gives this error when I visit the page:

TemplateDoesNotExist at /

static_pages/templates/static_pages/index.html

Request Method:     GET
Request URL:    http://localhost:8000/
Django Version:     1.8.3
Exception Type:     TemplateDoesNotExist
Exception Value:    

static_pages/templates/static_pages/index.html

Exception Location:     /usr/local/lib/python2.7/dist-packages/django/template/loader.py in get_template, line 46

 '/usr/lib/python2.7/dist-packages/ubuntu-sso-client']

Server time:    Wed, 19 Aug 2015 19:27:59 +0000

The error says it can not find a template at static_pages/templates/static_pages/index.html . But that is exactly where it is? What's going on?

If I do not use render and just return 'hello world' it does not give an error, so I do not think it is a problem with routing.

Here is my project settings file:

So, I'm guessing I don't have my settings configured correctly?

Answer 1

You need to add your app to the installed apps and it will find your templates folder automatically.

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'static_pages',
)

the APPS_DIR setting takes care of loading anything in the templates directory for any app you have installed without specifically specifying the directory.

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