Hello !

I have created onchange function based on one2many field. Here have some field like as float, int,char , boolean . The main fact is that the boolean field didn't change when i select any one2many field value . reference_id contains one2many field. The boolean field have sorted the previous value . it's not changing .Please tell me how can i solve this ?

here is the model views:

reference_id = fields.Many2one('eem.pre_costing', string='Reference :', domain=[('state', '=', 'confirm')],
                               required=True, tracking=True)
purpose = fields.Text(string='Purpose :', required=True, tracking=True)
requested_amount = fields.Float(string="Requested Amount :")

" boolean field

purchase = fields.Boolean(string='Purchase :', default=False, tracking=True)
miscellaneous = fields.Boolean(string='Miscellaneous :', default=False, tracking=True)
gift_donation = fields.Boolean(string='Gift & Donation :', default=False, tracking=True)
printing_stationery = fields.Boolean(string='Printing&Stationery :', default=False, tracking=True)

onchange function

@api.onchange('reference_id')
def onchange_reference_id(self):
        if self.reference_id.purpose:
            self.purpose = self.reference_id.purpose
        if self.reference_id.total_pre_costing_amount:
            self.requested_amount = self.reference_id.total_pre_costing_amount
        if self.reference_id.purchase:
            self.purchase = self.reference_id.purchase
        if self.reference_id.miscellaneous:
            self.miscellaneous = self.reference_id.miscellaneous
        if self.reference_id.gift_donation:
            self.gift_donation = self.reference_id.gift_donation
        if self.reference_id.printing_stationery:
            self.printing_stationery = self.reference_id.printing_stationery

    else:
        self.purpose = ''
        self.purchase = ''
        self.miscellaneous = ''
        self.gift_donation = ''
        self.printing_stationery = ''
