Django Cheat Sheet
Introduction
The article covers several important database operation commands such as createcachetable, dbshell, dumpdata, flush, inspectdb, loaddata, makemigrations, migrate, showmigrations, sqlflush, sqlmigrate, sqlsequencereset, squashmigrations, and testserver. These commands will help you to manage your database more efficiently and will save you a lot of time.
Moreover, the article also covers several environment configuration commands such as startproject, startapp, compilemessages, and makemessages. These commands will help you to set up your Django environment quickly and easily.
Lastly, the article covers development debugging commands such as check, diffsettings, runserver, shell, sendtestemail, and test. These commands will help you to debug your application and test it thoroughly.
