Running migrations to generate the user table

Now, we will run many scripts to run migrations and generate the necessary table in the PostgreSQL database. Make sure you run the scripts in the terminal or the Command Prompt window in which you have activated the virtual environment and that you are located in the api folder.

Run the first script that populates the migration script with the detected changes in the models. In this case, it is the second time we populate the migration script, and therefore, the migration script will generate the new table that will persist our new User model: model:

python migrate.py db migrate

The following lines show the sample output generated after running the previous script. Your output will be different according to the base folder in which you have created the virtual environment.
