How to Load Templates in Django for specific application?

Question

So I am learning Django at in advanced level. I already know how to include templates from BASE_DIR where manage.py is located. However I wanted to know how to locate templates in the specific app in Django.

For example, I have a project named mysite and an app called polls.

I then specify the templates directory in settings.py:

DIRS=[os.path.join(BASE_DIR, "templates")]

However, I do not know how to set a templates directory specific to the polls app. This is the project structure:

.
├── db.sqlite3
├── manage.py
├── mysite
│   ├── asgi.py
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── polls
│   ├── admin.py
│   ├── apps.py
│   ├── __init__.py
│   ├── migrations
│   │   ├── __init__.py
│   ├── models.py
│   ├── static
│   │   ├── images
│   │   ├── scripts.js
│   │   └── style.css
│   ├── tests.py
│   ├── urls.py
│   └── views.py
└── templates
    ├── polls
    │   └── index.html
    └── static
        ├── images
        ├── scripts.js
        └── style.css

I wanted it to look like this.

.
├── db.sqlite3
├── manage.py
├── mysite
│   ├── asgi.py
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── polls
│   ├── admin.py
│   ├── apps.py
│   ├── __init__.py
│   ├── migrations
│   │   ├── __init__.py
│   ├── models.py
│   ├── static
│   │   ├── images
│   │   ├── scripts.js
│   │   └── style.css
│   ├── templates            <- New
│   │   ├── polls
│   |   │   ├── index.html
│   ├── tests.py
│   ├── urls.py
│   └── views.py
└── templates
    ├── polls
    │   └── index.html
    └── static
        ├── images
        ├── scripts.js
        └── style.css

Answer 1

If you have the app specific templates located at "polls/templates/polls/" then you need to add that path to TEMPLATES in settings.py as below

TEMPLATES = [
        {
            'BACKEND': 'django.template.backends.django.DjangoTemplates',
            'DIRS': [os.path.join(BASE_DIR, 'polls/templates')], # here the app template path is set 
            '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',
                ],
            },
        },
    ]

And while rendering template the path should have a folder preffix like

render(request, 'polls/index.html', context)

UPDATE: As in above settings APP_DIRS is set to True, django will automatically look into <yourapp>/<templates> directory for the templates even if the app template paths are not explicitly specified.
