Answer 1

1. Add a templates directory at the project root, and add it to your TEMPLATE_DIRS setting.
2. Add a base.html to that directory.
3. Extend it wherever you want using {% extends 'base.html' %}

Answer 2

For Django versions above 1.8 the upgrade doc suggests the vanilla settings (for most non-advanced django tangoers like me) be added to your settings.py:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [(os.path.join(BASE_DIR, 'my_Templates_Directory')),],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                # Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
                # list if you haven't customized them:
                'django.contrib.auth.context_processors.auth',
                'django.template.context_processors.debug',
                'django.template.context_processors.i18n',
                'django.template.context_processors.media',
                'django.template.context_processors.static',
                'django.template.context_processors.tz',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

Both BACKEND and OPTIONS were required, otherwise I had errors relating to 'INVALID BACKEND' and 'django.contrib.auth.context_processors.auth' must be in TEMPLATES'.

In current Django (1.10) TEMPLATE_DIRS is deprecated, so:

1. Add a templates directory at the project root,

2. In settings.py find TEMPLATES -> DIRS and add it like this:

   TEMPLATES = [
   {
       ...
       'DIRS': [(os.path.join(BASE_DIR, 'templates')),],
       ...
   }
   

3. Add a base.html to that directory.

4. Extend it wherever you want using {% extends 'base.html' %}
