Script de gestion des migrations de base de données VWB
|
||||
|
||||
Usage:
|
||||
python manage.py init # Initialiser les migrations (une seule fois)
|
||||
python manage.py migrate # Créer une nouvelle migration
|
||||
python manage.py upgrade # Appliquer les migrations pendantes
|
||||
python manage.py downgrade # Annuler la dernière migration
|
||||
python manage.py stamp # Marquer une révision comme appliquée
|
||||
python manage.py current # Afficher la révision actuelle
|
||||
python manage.py history # Afficher l'historique des migrations
|
||||
python manage.py backup # Sauvegarder la base de données
|
||||
python manage.py status # Afficher le status complet
|
||||
|
||||
Exemple de workflow de migration:
|
||||
1. Modifier les modèles dans db/models.py
|
||||
2. python manage.py migrate "Description du changement"
|
||||
3. Vérifier le fichier de migration généré dans migrations/versions/
|
||||
4. python manage.py upgrade
