i'm using ODOO8, and working with :
crane.work.order
contains
tasks_id: that is a One2many(crane.task)
& crane.task
contains
equipment_id=Many2one(crane.equipment)
so my question is how can i convert tasks_id till i can have 1 workorder with 1 task and 1 equipment, should i override the tasks_id field or create a new one ? -Sorry i'm an odoo beginner-
