将瞬态模型的值传递给One2many - odoo 13 (值错误)

Question

型号：

 class AjaxTimesheet(models.Model):

    _name = "ajax.timesheet" 

timesheet_id = fields.Many2one(comodel_name='ajax.timesheet',string='Timesheet', compute='_compute_timesheet_id')

 @api.depends('created_by')
    def _compute_timesheet_id(self):
        # Compute Timesheet Id for given Timesheet
        for rec in self:
            rec.timesheet_id = rec._origin.id

TransientModel：

 class TimesheetData(models.TransientModel):
        _name = "timesheet.data"
        _description = "Timesheet Data" 

time_task_ids = fields.One2many('ajax.timesheet','timesheet_id',string='Timesheet')



  @api.onchange('created_by','created_date')
            def on_change_created_by(self):

                # list the task in timesheet based on user
                task_ids = self.env['prj.task'].search([('task_assigned_to','=',self.created_by.id),
                                                        ('state','=','ongoing'),('child_ids','=',False)])
                task_list = []
                for task in task_ids:
                    timesheet = self.env['timesheet.timesheet'].search([('task_ids', '=', task.id)])
                    tot_time = 0
                    for i in timesheet:
                        tot_time += i.duration
                    tot_duration = task.task_planned_hours - tot_time
                    vals = {
                        'task_ids': task.id,
                        'created_date': self.created_date,
                        'created_by': self.created_by.id,
                        'prj_project_id':task.prj_project_id.id,
                        'planned_hour': task.task_planned_hours,
                        'task_deadline_date': task.task_deadline_date,
                        'balance_hour': tot_duration,
                        'ref_parent_id':  task.task_assigned_to.parent_id.id,
                    }
                    task_list.append((0, 0, vals))
                self.time_task_ids = task_list

这一行中的错误: self.time_task_ids = task_list ValueError: ajax.timesheet.timesheet_id: timesheet.data(，)的错误值

timesheet.data(，)-我猜对象ID应该是ajax.timesheet模型的，但是这里是来自timesheet.data(，)的，这就是为什么错误值是错误的。修复此错误的任何解决方案。

错误: Odoo Server错误

Answer 1

你必须这样做：

new_record = self.env['ajax.timesheet'].create({
 //create record fields;
})

self.env.cr.commit()
task_list.append(new_record.id)

self.update({
    'time_task_ids': (6, 0, task_list)
})
self.env.cr.commit()

因为您正在更新此字段@api.onchange.的值。因此，当您想要更改模型字段的数据时，必须根据场景使用update或write方法。

这就是如何输入价值的方法。

(0，0，{value })链接到需要用给定值字典创建的新记录

(1，ID，{value })使用id = ID更新链接记录(在其上写入值)

(2，ID)用ID = id删除和删除链接的记录(调用ID上的unlink，这将完全删除对象，以及指向对象的链接)

(3，ID)使用id = ID切断链接到链接记录的链接(删除两个对象之间的关系，但不删除目标对象本身)

(4，ID)用id = ID链接到现有记录(添加关系)

(5)取消所有链接(如对所有链接记录使用(3，ID) )

(6，0，ID)替换链接ID列表(如对ID列表中的每个ID使用(5)然后(4，ID))
