+======== update django database to reflect changes in existing models without any migration system (e.g., south) =========
+
+$python manage.py reset <your_app>
+
+This will update the database tables for your app, but will completely destroy any data that existed in those tables. 
+If the changes you made to your app model do not break your old schema (for instance, you added a new, optional field) 
+you can simply dump the data before and reload it afterwards, like so:
+
+
+$python manage.py dumpdata <your_app> > temp_data.json
+$python manage.py reset <your_app>
+$python manage.py loaddata temp_data.json
+
+If your changes break your old schema this won't work - in which case tools like south or django evolution are great.
