To create a migration for this model, use the following command. It will create a migration file inside the migration folder.
$ python3 manage.py makemigrations
This migration file contains the code in which a Migration class is created that contains the name and fields of employee table. // 0001_initial.py
After creating a migration, migrate it so that it reflects the database permanently. The migrate command is given below.
$ python3 manage.py migrate
If no app-name is provided, it shows all migrations applied to the project.
$ python3 manage.py showmigrations
We can get app-specific migrations by specifying app-name, see the example.
$ python3 manage.py showmigrations myapp $ python manage.py runserver
