I discovered that specifying the templates settings as following, raises an error when rendering the template:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'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',
],
'loaders': [
('django.template.loaders.cached.Loader', [
'django.template.loaders.filesystem.Loader',
'django.template.loaders.app_directories.Loader',
]),
],
},
},
]
urls.py:
from django.conf.urls import include, url
from django.contrib import admin
from django.views.generic import TemplateView
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^$', TemplateView.as_view(template_name='test.html')),
]
Test template is just an empty file
