You’ve covered quite a bit of ground in these videos, so let’s sum up what you’ve seen. You’ve seen what migrations are and the problems they solve; how they can avoid you having to learn to write SQL code and stick to writing Python code instead; how to create migrations using manage.py makemigrations; how to apply migrations with manage.py migrate; how changing a model in your Django code means all you have to do is to create and apply a new migration; how to list migrations with manage.py showmigrations; how to unapply migrations by reverting back to an earlier migration;
00:51 and how to name migrations, making coming back to your code later easier as they’ll have a descriptive name rather than merely a timestamp.
01:02 I hope you’ve enjoyed this video and we’ll see you soon at Real Python.

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?
