I code part as below :

class Selection(models.Model):
    _name = 'selection.model'
    _rec_name = 'select'
    select = fields.Char(string='selections', required=True)

class Checks(models.Model):
    _name = 'buy.goods'
    strs = fields.Char()
    results = fields.Many2one('selection.model', string='Selections')

    @api.onchange('strs')
    def _get_results(self):
        goods = self.strs.split(',')
        ...
I want to show all items of 'goods' as selections of 'results' field; and when 'strs' field is changed, the selections of 'results' field should be updated at once. so how shall I code for this?

Hi,

if you want to display the many2one field like selection you can use widget="selection" and you can write a method on onchange of many2one field and return domain in that method based on condition.

@api.onchange('result')
def onchange_result_ids(self):
    if self.strs:
        domain = {'result': [(condition)]}
        return {'domain': domain}

thanks for your reply;

but i think the effect of your code is select some items but what i means is that the select items of 'result' are from 'strs'; for example, 'strs' = 'this is good'; then the select items list of 'result' should be ['this','is','good']
