Yes the structure of my project is more or less like that but I've not two but 6 apps all with 'from django.db import models' in models.py In several model (more than two), I'm using foreign keys to different models. For now the site doesn't do much, I'm using the database created with the models in other files in the project folder. So if the __init__.py is not a good place to start operations at server startup, where should I put it ? -- You received this message because you are subscribed to the Google Groups "Django users" group.
