What need to set in settings.py to tell Django which host to use when connecting to database code example

Example 1: database default code in settings django

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'mydatabase',
    }
}

Example 2: settings.debug django

# Required Imports
from django.conf.urls.static import static
from django.conf import settings

# Below Urlpatterns
if settings.DEBUG:
	urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
