Hello Moh,

You can do this by using @api.onchange('many2one_field')

You can refer onchange methods in the default odoo addons.

Hope this helps.

Thank you

Hi moh,

It's possible, you can do this using onchange method that i explain you bellow:

Step-1: create a many2one field like this:

many2one_field = fields.Many2one('One2manyFieldModelName', string="Many2one Field")

step-2: declare one2many field for storing onchange records

one2many_record_field = fields.One2many('Many2oneFieldModelName', 'field_name')

step-3 create onchange method using:

@api.onchange('many2one_field')

    def _onchange_many2one_field(self):

            self.one2many_record_field = self.env['One2manyFieldModelName'].search([('One2manyFieldName', '=', self.many2one_field)])

just do the above step and done.

Here i have created one Many2one field that contain one2many field data, after that i created one one2many field that store onchange records as you want, then after i just call onchange method and store records using search function, you can use any functions like mapped, search, browse etc.

i hope it's understandable for you, if not just comment.

accept the answer if usefull..

Thank you..
