This document is for Celery's development version, which can be
significantly different from previous releases. Get old docs here:
celery.app.default_app = <Celery default:0x7f720e966110>
Function returning the app provided or the default app if none.
The environment variable CELERY_TRACE_APP is used to
trace app leaks. When enabled an exception is raised if there
is no active app.
celery.app.default_loader = 'djcelery.loaders.DjangoLoader'
The ‘default’ loader is the default loader used by old applications.
This is deprecated and should no longer be used as it’s set too early
to be affected by –loader argument.
