如何合并批号/序列号

如何解决如何合并批号/序列号

我想添加一个向导，其中 Many2many 字段为 'stock.production.lot'，仅显示加倍 Lot/Serial Number 的记录 我做了获取过滤记录的功能，现在我需要显示它

class DoublingNumber(models.TransientModel):
    _name = 'doubling.number'
    

    double_number_id =fields.Many2many('stock.production.lot',string="Numéros en doublant" )

     @api.multi
        def _default_double_number(self):
            log.warning("Hola")
            double_record = []
            records =self.env['stock.production.lot'].search([])
            for record in records :
                for record2 in records :
                    if record.name == record2.name and record.product_id != record2.product_id :
    
                        double_record.append(record2)    
                         
                        break
            return double_record

现在如何显示？？！

解决方法

尝试在字段定义中调用默认函数，但在字段之前定义函数，并按以下方式定义：

class DoublingNumber(models.TransientModel):
    _name = 'doubling.number'

    @api.model
    def _default_double_number(self):
        log.warning("Hola")
        double_record = self.env['stock.production.lot']
        records =self.env['stock.production.lot'].search([])
        for record in records :
            for record2 in records :
                if record.name == record2.name and record.product_id != record2.product_id :

                    double_record += record2  
                     
                    break
        return double_record
    
    double_number_id =fields.Many2many('stock.production.lot',string="Numéros en doublant",default = _default_double_number)

祝你好运:)
