Question

我有一个字段，我想计算它的变化值，但我不希望用户可以修改它。

如果我将字段设置为readonly = 1或editable = 0，则该值不存储。

我正在尝试在发票上设置全局折扣

class account_invoice(models.Model):
    _inherit = "account.invoice"

    global_discount_p = fields.Float('Descuento porcentaje')
    global_discount = fields.Float('Descuento')
    neto = fields.Float('Neto')

    @api.one
    @api.depends('invoice_line.price_subtotal', 'tax_line.amount','global_discount_p')
    def _compute_amount(self):
        ret = super(account_invoice,self)._compute_amount()
        if self.type == 'in_invoice':
            self.neto = self.amount_untaxed
            discount = self.global_discount_p/100
            self.global_discount = self.neto * discount
            self.amount_untaxed = self.neto - self.global_discount

            for line in self.tax_line:
                line.base = self.amount_untaxed
                line.amount = line.amount - (line.amount * discount)

            self.amount_tax = sum(line.amount for line in self.tax_line)
            self.amount_total = self.amount_untaxed + self.amount_tax

        return ret

在布局中：

<xpath expr="//field[@name='amount_untaxed']" position="before">
                <field name="neto" readonly="1"/>
                <field name="global_discount_p" onchange="_compute_amount"/>
                <field name="global_discount" readonly="1"/>
            </xpath>

如果我从字段

中删除readonly =“1”attrs，它效果很好

Answer 1

在odoo11中，您可以在xml文件中使用force_save="1"

希望它将对您有帮助！

Answer 2

尝试将字段定义为

neto = fields.Float('Neto', compute='_compute_amount', store=True)
global_discount = fields.Float('Descuento', compute='_compute_amount', store=True)

Answer 3

在account_invoice类中重写这两个方法并声明字段，如

global_discount = fields.Float('Descuento', readonly=True)



@api.model
def create(self, vals):
    if vals['global_discount']:
        if vals['type'] == 'in_invoice':
        vals['neto'] = vals['amount_untaxed']
        discount = vals['global_discount_p']/100
        vals['global_discount'] = vals['neto'] * discount
        vals['amount_untaxed'] = vals['neto'] - vals['global_discount']

        for line in vals['tax_line']:
            line.base = vals['amount_untaxed']
            line.amount = line.amount - (line.amount * discount)

        vals['amount_tax'] = sum(line.amount for line in vals['tax_line'])
        vals['amount_total'] = vals['amount_untaxed'] + vals['amount_tax']
    res = super(PersonInformation, self).create(vals)
    return res

@api.multi
def write(self, vals):
    if vals['global_discount']:
        if vals['type'] == 'in_invoice':
        vals['neto'] = vals['amount_untaxed']
        discount = vals['global_discount_p']/100
        vals['global_discount'] = vals['neto'] * discount
        vals['amount_untaxed'] = vals['neto'] - vals['global_discount']

        for line in vals['tax_line']:
            line.base = vals['amount_untaxed']
            line.amount = line.amount - (line.amount * discount)

        vals['amount_tax'] = sum(line.amount for line in vals['tax_line'])
        vals['amount_total'] = vals['amount_untaxed'] + vals['amount_tax']
    res = super(PersonInformation, self).create(vals)
    return res

在布局中：

<field name="global_discount" readonly="1"/>

我希望这会对你有所帮助。

如何在odoo模型中节省Readonly / editable false字段的价值？
