How to set Configuration Values from Database for mandatory_billing_fields
In website_sale mandatory shipping and billing fields are directly set in the class website_sale in the file main.py.
I try to make this more useful and set this attributes by settings in the database.
The problem is that these attributes are directly set in the class - so not wrapped in a function. So no Database Cursor is available to fetch the values from this attributes(variables).
I tried to build my own Database Access with:
registry = RegistryManager.get(tools.config.options.get('db_name'))
But this only gives me access to basic models like res.partner but not to models like website or product.product?!? Maybe they are not already loaded / build at that time?
So what would be the correct way to fetch the values for mandatory_billing_fields from the database model website where i wrote them to?!?
