Comment:
Aymeric suggested to enable the cached template loader by default when
`DEBUG = False` and no `‘loaders’` options is specified.
This is technically backwards-incompatible, but:
- people who don’t usually configure it will get a free performance boost
in production
- people who do will be able to simplify their configurations
Currently many projects have a variant of this awful pattern:
{{{
# settings/prod.py
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'OPTIONS': {
'loaders': [
('django.template.loaders.cached.Loader', [
'django.template.loaders.app_directories.Loader',
]),
],
},
},
]
# settings/dev.py
from .prod import *
TEMPLATES[0]['OPTIONS'].update({
'loaders': [
'django.template.loaders.app_directories.Loader',
],
})
}}}
His suggestion makes it possible to remove the configuration of
`‘loaders’` and to rely only on `DIRS` and `APP_DIRS` instead.
