Hello,

I'm trying to replace driver_id related to res.partner in a driver_id field related to hr.employee using :

    driver_id = fields.Many2one('hr.employee', string="Driver", store=True, ondelete="cascade")

The problem is when I do this i receive the KeyError: plan_to_change_car

This happens because plan_to_change_car is related to driver_id. How can I do? If I create a new field driver_id and I disabled the driver_id related to res.partner I received the same KeyError.

I tried also to write in hr.employee this field

   driver_ids= fields.One2many('fleet.vehicle', 'employee_id', string='Driver')

But nothing.

Thank you in advance
