How to add records to one2many field using onchange event

Question

In stock.picking form, I would like to know how can I add an item to the one2many field move_lines using an onchange event on the partner_id field.
Both of the field with the onchange event and the one2many field that needs to add records belongs to the same class

I have solved it by the following code. Hope it helps you.
@api.onchange('customer_id')
def _onchange_customer_id(self):
lines =[]
for rec in self.customer_id.site_ids:
result ={'name':rec.name}
lines.append((0,0, result))
self.site_ids = lines

Hi Aldennis

suppose your  one2many  field name is  my_field   then

define list in first ex ..   r=[]

then

r.append({'first_field_ino2m':'my vlaue','second......':'my second value'})

you can add more field availble in That  one2many  object for another record just continuous append same after all append completed just add  r  in  my_field':r,

exm.    vals.update({'my_field':r})

Thanks

You need to return all IDs in one list with your one2many field in values .

Syntax:

return {'value': {'your_one2many_field': list_of_ids}}

For example my_emp_ids is my one2many field of hr.employee and I want to fill it when I will select *Department*. I want *all employees* of selected *Depratment*.

def onchange_department(self, cr, uid, deprt_id):
employee_ids = self.search(cr, uid, [('department_id', '=', deprt_id)])
return {'value': {'my_emp_ids': employee_ids}}
