We have persisted many games in our database and we have added a new owner
field for the games that are a required field. We don't want to delete all the existing games, and therefore, we will take advantage of some features in Django that make it easy for us to make the changes in the underlying database without losing the existing data.
Now we need to retrieve the id
for the superuser we have created to use it as the default owner for the existing games. Django will allow us to easily update the existing games to set the owner user for them.
Run the following commands to retrieve the id
from the auth_user
table for the row whose username
matches 'superuser'
. Replace your_games_super_user
with the username you selected for the previously created superuser. In addition, replace your_games_user_name
in the command with the username you used to create the PostgreSQL 10.5 database and your_games_password
with your chosen password...
