Since version 1.7, Django has come with built-in support for database migrations. In Django, database migrations usually go hand in hand with models: whenever you code up a new model, you also generate a migration to create the necessary table in the database. However, migrations can do much more.
With this course you’ll get comfortable with Django migrations and learn how to create database tables without writing any SQL, how to automatically modify your database after you changed your models, and how to revert changes made to your database.

Really nice course. For me two important things that I learned from this course that I consider a senior behavior are:
1 - makemigrations per app - thinking for example like commits in git where you try to change only one thing and commit in order to make easy go one step back. Same thinking for migrations.
2 - define a descriptive names for migrations - it’s nice to look to the migration and know what is going on. And where I have to go if I wanna to go back to a previous schema.
And about you guys, What did you consider an important learning in this course?
