Shell commands in Django

shell tools

Django's manage tool provides shell commands to help us configure the running environment of the current project (such as connecting to a database, etc.) so that we can execute test python statements directly in the terminal.

Enter the shell through the following command

python manage.py shell

Import two model classes for later use

from book.models import BookInfo,PeopleInfo

This article's shell is a command of the manage tool

Remember the administrator created before, also use the manage command, then let's talk about this manage
