[Answer]-OpenERP DB Connectivity with Django

You can do it in a pythonic (or django) mode.

Do a introspect to the openERP DDBB and generate the django models with inspectdb (link)

python manage.py inspectdb > models.py

Connect to the DDBB with the multidb django module. Access to data with django models or create raw sql queries.

You have to be careful with this solution.

What about connecting to openERP by REST?. RESTful-openERP
