python - 如何使 odoo 计算关系字段在导入时自行计算？

Question

我在 View 开始、结束、忽略和范围中添加了四个字段范围字段是根据开始和结束字段计算的，有时使用忽略来弹出记录该方法运行良好，但将数据从 Excel 工作表导入模式时，不会计算范围字段这是整个代码​

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")

Answer 1

您的字段rang未计算，因为您从未告诉过它。只需在字段定义上添加 compute 参数即可:

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

并且您应该在计算方法上使用 api.depends 而不是 api.onchange:

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

在客户端，您将看到 api.depends 将具有与 api.onchange 相同的结果。
