My Odoo 11 system already has records created by users. When I create a new function to add new features to odoo application, the function only applies to new records created after the existence of the new function. To apply it to existing records, I must edit each old record,change the value of one the fields used by the function, and save.
My question: is there a way for a new function created in the python source to apply to all records automatically without needing to edit and save each old record?
