ADMIN_SHELL_IMPORT_DJANGO

type : bool

default : True

If flag is set on True, then useful libraries and packages from Django will be automatically imported to shell. For example: from django.conf import settings, so in shell you have directly access to attributes from this module (e.g settings.INSTALLED_APPS). List of automatically imported modules is displayed on top of console (screen below). If you want disable auto import for django packages, set this flag to False.

Nont: If during import occurred error `ImportError` then this module will be omitted.

ADMIN_SHELL_IMPORT_MODELS

type : bool

default : True

This flag is similar to ADMIN_SHELL_IMPORT_DJANGO but regarding auto import of models from all registered applications. If flag is set on True, then models from all apps will be automatically imported to shell. For example: from django.contrib.auth.models import Permission, Group, User, so in shell you have directly access to this classes. List of automatically imported models is displayed on top of console. If you want disable auto import for models, set this flag to False.

Nont: If during import occurred error `ImportError` then this module will be omitted.

ADMIN_SHELL_CLEAR_SCOPE_ON_CLEAR_HISTORY

type : bool

default : False

This flag is used to enable the gargabe collector on the declared variables from the shell execution when the "clear history" is executed. If this flag is set to True, then all the declared variables will be ERASED and FREED from memory on runtime when "clear history" is used. If you want to persist indefinitly all declared variables on the shell, set this flag to False.

BEWARE: leaving this disabled is not recomended on production code!
