Python/Odoo10: AttributeError: 'dict' object has no attribute '_sale_postprocess'

Question

我是 python 的新手，不知道如何解决这个错误。请指导我。我想对 'unit_amount' 浮点字段进行验证，如果该字段的值大于 8，那么它应该给出一条错误消息并且不应保存该值，尽管我单击了 'Save' 按钮。

我收到以下错误：

忘记覆盖 ORM create 方法。相反，以这种方式创建约束：

from odoo import api, fields, models, _
from odoo.exceptions import ValidationError


class AccountAnalyticLine(models.Model):
    _inherit = 'account.analytic.line'

    ...

    @api.multi
    @api.constrains('unit_amount')
    def _check_unit_amount(self):
        for line in self:
            if line.unit_amount > 8:
                raise ValidationError(
                    _('The unit amount should not be more than 8 hours '
                      'per project and Standard 40 Hours/Week')
                )
