How to automate createsuperuser on django?

Question

I want to auto run manage.py createsuperuser on django but it seams that there is no way of setting a default password.

How can I get this?

Answer 1

This is what I cobbled together for Heroku post_deploy and a predefined app.json variable:

if [[ -n "$CREATE_SUPER_USER" ]]; then
    echo "==> Creating super user"
    cd /app/example_project/src
    printf "from django.contrib.auth.models import User\nif not User.objects.exists(): User.objects.create_superuser(*'$CREATE_SUPER_USER'.split(':'))" | python /app/example_project/manage.py shell
fi

With this you can have a single env variable:

CREATE_SUPER_USER=admin:admin@example.com:password

I like the shell --command option, but not sure how the get newline character in the command script. Without the newline the if expression results in syntax error.
