The view in the Django framework to realize an interface has the following a few lines of code:

With concurrent. Futures. ProcessPoolExecutor () as executor:
Executor. Submit (fn)

Fn function refers to the Django model object
When a new process to load when the model error:
Django. Core. Exceptions. AppRegistryNotReady: Apps aren 't the loaded yet.

New process without the original process Apps information

Running Django underlying trigger Django. The setup ()

Def setup (set_prefix=True) :
"" "
Configure the Settings (this happens as a side effect of accessing the

Set the thread - local urlresolvers script prefix if ` set_prefix ` is True.
"" "
The from the django. Apps import apps
The from the django. Conf import Settings
The from the django. Urls import set_script_prefix
The from the django. Utils. The log import configure_logging

Configure_logging (Settings. LOGGING_CONFIG Settings. LOGGING)
If set_prefix:
Set_script_prefix (
'/' if Settings. FORCE_SCRIPT_NAME is None else Settings. FORCE_SCRIPT_NAME
)

Because ThreadPoolExecutor is still in the original process, so the concurrent can perform normal

But ProcessPoolExecutor parallel will create a new process, the process of different apps information isolation between the
