如何在 odoo 模型中保存只读/可编辑错误字段的值？答案

【问题标题】：How to save value on Readonly / editable false fields in odoo Models?如何在 odoo 模型中保存只读/可编辑错误字段的值？

【问题描述】：

我有一个字段，我想计算它的更改值，但我不希望用户可以修改它。

如果我将该字段设置为 readonly=1 或 editable=0，则不会存储该值。

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，效果会很好

【解决方案1】：

在odoo11你可以在xml文件中使用force_save="1"

希望对你有帮助！！

【讨论】：

force_save="1" 适用于只读字段，因此您将保存此字段，它工作完美，非常感谢
也适用于 12.0，谢谢！！阅读更多关于这个here
在 11.0 中，如果您将 1 应用于 invoice_line_ids，则在树视图（发票行）中，readonly="1" 将不起作用（它禁用 editable="bottom" 并且记录是可编辑的），但是如果您申请树视图中的每个字段，它就可以工作。解决了我的问题，非常感谢！

【解决方案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)

【解决方案3】：

在您的 account_invoice 类中覆盖这两个方法并声明如下字段，

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"/>

希望对你有帮助。
