What is difference between 'makemigrations' and 'migrate' ?

makemigration will create the migration. A migration basically tells your database how it's being changed(i.e new column added, new table, dropped tables etc.). migrate is what pushes your changes to your database. It will run all the migrations created(or the ones that haven't been pushed yet). Hope this helps :)

Someone else asked this, and here is Moderator Chris Freeman's answer:

"It is necessary to run both the commands to complete the migration of the database tables to be in sync with your models.

makemigrations simply analyzes your current models for any changes that would be out of sync with your database and creates a migrations file that can be used to bring the in sync. If left at this point, your models would still be out of sync with your database possibly breaking your code that queries the database.

migrate is the command to "Make It So!" and apply the changes noted during the makemigrations phase.

Applying [app] to either of these commands simply adds focus to that "app" and doesn't inspect all of your apps."
