如何更新触发计算功能的寄存器以外的寄存器

如何解决如何更新触发计算功能的寄存器以外的寄存器

我想获取产品绑定并将其显示在视图中（这有效）。如果它没有绑定，我必须检查该产品是否是物料清单的一部分，如果是，我必须查找父级的绑定并显示该绑定（这是行不通的，它不起作用） t 给出错误，但它不会将父级的值分配给子级）。

class ProductProduct(models.Model):
    _inherit = 'product.product'

    main_endado_bind = fields.Char(
        string='Main Endado Bind',store=True,compute='_get_endado_bind'
    )

    @api.multi
    @api.depends('endado_bind_ids','bom_ids.bom_line_ids')
    def _get_endado_bind(self,external_id=''):
        for product in self:
            if product.endado_bind_ids:
                parent_external_id = product.endado_bind_ids[0].external_id
                product.main_endado_bind = parent_external_id
                for line_product in product.bom_ids.bom_line_ids:
                    line_product.product_id._get_endado_bind(external_id=parent_external_id)
            elif external_id:
                product.main_endado_bind = external_id

修改 BOM 时，我想将父项的绑定 ID 分配给新材料，但触发计算的是父项，因为修改的是其 BOM。

如果我使用 write 而不是最后一行，则会出现此错误：

KeyError: 79 是 bom 行的 id。

有什么想法吗？谢谢！

解决方法

这里有一些关于您的错误的想法。

main_endado_bind 已声明为 char 数据类型。所以它总是存储字符值。

根据您的代码，似乎 parent_external_id 具有整数值。您正在为 char 数据类型字段分配整数值。所以它不起作用。

要解决这个问题，我们必须显式地将类型转换为 char。例如，

product.main_endado_bind = str(parent_external_id)
