DB Interactions

Create a migration script (located in /migrations/<id_migration>.py):

$ python manage.py makemigrations <myapp>

This script can be manually modified before execution (useful if some updates, add index, etc. should be performed).

Show the SQL alter scripts produced by the generator (without do anything to the database):

$ python manage.py sqlmigrate <myapp> <nnnn>

Django deals with various database syntaxes (e.g. auto_increment for mysql, serial for postgres, etc). Here some of its assumptions (that can be overridden):

Tables names: application name + lowercase name of the model.
Primary key (IDs) are added automatically
An "_id" is appended to foreign keys field names

Actually migrate:

$ python manage.py migrate

Django takes all the migrations that haven't been applied (using a special table) and runs them. In short, the needed operations are:

$ python manage.py makemigrations <myapp>
$ python manage.py migrate
