how to make odoo computed relation field caculate itself while importing?

i'am added four fields in a view start,end,ignore and range range field is computed from start and end field and sometimes using ignore to pop up a record the method is working well but while importing data into a mode from excel sheet range field isn't computed this the whole code​

class relate(models.Model):
_name = 'relate'
_rec_name = 'car'

@api.multi
@api.onchange('start', 'end', 'ignore')
def years_rang(self):
    for rec in self:
        if rec.start and rec.end:
            record = [int(x) for x in range(int(rec.start), int(rec.end) + 1)]
            list = []
            if rec.ignore:
                try:
                    record.remove(int(self.ignore))
                    list = []
                except ValueError:
                    return {'warning': {'title': 'Warning!', 'message': "the Ignored year doesn't in range"}}
            for item in record:
                range_id = self.env['yearrange'].create({'name': str(item)})
                list.append(range_id.id)
            rec.rang = [(4, x, None) for x in list]
        pass
start = fields.Char(string="", required=False, )
end = fields.Char(string="", required=False, )
rang = fields.One2many(comodel_name="yearrange", inverse_name="product_id",store=True, string="Years" ,)
ignore = fields.Char(string="Ignore", required=False, ) 


class yearrange(models.Model):
    _name = 'yearrange'
    _rec_name = 'name'
name = fields.Char()
product_id = fields.Many2one(comodel_name="relate")

Your field rang is not computed, because you never told it to be. Just add compute parameter on field definition:

rang = fields.One2many(
    comodel_name="yearrange", inverse_name="product_id",
    compute="years_rang", store=True, string="Years" ,)

And you should use api.depends on the computation method instead of api.onchange:

@api.multi
@api.depends('start', 'end', 'ignore')
def years_rang(self):
    # ...

On client side you will see, that api.depends will have the same outcome like api.onchange.
