Migrations

    • <ENV> manage.py syncdb
    • <ENV> manage.py migrate
  • Migrate on model change:
    • manage.py schemamigration app_name --auto

Internationalization

  • How Django discovers translations
  • Create or update message files:
    • manage.py makemessages -l de
  • Compile:
    • manage.py compilemessages -v 2 -l de
  • Compile all:
    • bash compilemessages.sh
