Django: Module "django.template.loaders.filesystem" does not define a "Loader" callable template source loader

I created a pretty basic Django project using django-admin and I'm now running into the following problem when I try to view my admin application in the browser while running with manage.py runserver:

ImproperlyConfigured at /admin/
Module "django.template.loaders.filesystem" does not define a "Loader" callable template source loader

For a reference, here's my settings.py file:

# Django settings for mine project.

DEBUG = True
TEMPLATE_DEBUG = DEBUG

ADMINS = (
    # ('Your Name', 'your_email@domain.com'),
)

MANAGERS = ADMINS

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': '/tmp/mine.db',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

I had to comment out a bunch of stuff as 开发者_运维百科you can see and I had to use a different way of defining my database than the one that they provided. I had other errors being thrown if I left some of the other items in there. What did I do wrong?

Here you can see correct loader package-paths. It appears to me, you should use them.

django.template.loaders.filesystem.Loader
django.template.loaders.app_directories.Loader

Another way to fix would be to upgrade the Django installation.

That settings.py file appears to have been created for a more recent version of Django than what is currently installed.

Loader was added to django.template.loaders.filesystem in this revision.

It seems that you may want to comment out one of the DB settings as below, as the second set of database connection settings seems redundant:

    DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
    'NAME': '/tmp/mine.db',                      # Or path to database file if using sqlite3.
    'USER': '',                      # Not used with sqlite3.
    'PASSWORD': '',                  # Not used with sqlite3.
    'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
    'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
       }
    }

   #DATABASE_ENGINE = 'sqlite3'
   #DATABASE_NAME = '/tmp/mine.db'
   #DATABASE_USER = ''
   #DATABASE_PASSWORD = ''
   #DATABASE_HOST = ''
