Odoo 如何将现有记录添加到 one2many 字段?

Odoo How to add existed record to one2many field?

我想将我创建的记录添加到 one2many 字段。但是它会导致 ValueError: Expected singleton: product.job_line(762, 763)。

不知道为什么在JobContainer调用write方法的时候不分离成两个object而是合并成一个object。之后它会导致我之前告诉你的错误。

如何解决这个问题?

这是我的 SaleOrder 代码:

_logger = logging.getLogger(__name__)

class SaleOrder(models.Model):
    _inherit = 'sale.order'

    job_container = fields.One2many('job.container', 'order')
    discount = fields.Float()
    state = fields.Selection(
        [
            ('draft', 'Quotation'),
            ('sent', 'Quotation Sent'),
            ('pending', 'Pending Approval'),
            ('sale', 'Sales Order'),
            ('done', 'Locked'),
            ('cancel', 'Cancelled'),
        ],

            if order.discount > 1:
                total -= order.discount
            else:
                total -= total * order.discount

这是我的作业容器代码:

# -*- coding: utf-8 -*-

class JobContainer(models.Model):
    _name = 'job.container'
    _order = 'jobs_left'

    order = fields.Many2one('sale.order', readonly=True)

    job_lines = fields.One2many('product.job_line', 'container')
    jobs_left = fields.Integer(compute='update_job_lines_left')
    to_pending = fields.Boolean()

    def pending(self):
        self.order.pending()

    def unpending(self):
        self.to_pending = False
        for line in self.job_lines:
            line.to_pending = False

    @api.one
    def update_job_lines_left(self):
        left = 0
        for job_line in self.job_lines:
            if not job_line.is_finish and not job_line.state=='cancel':
                left += 1
        self.jobs_left = left

    def adjust_cost(self,cost):
        sum = 0
        for line in self.job_lines:
            if line.state=='active' and not line.is_finish:
                line.cost+=round(cost/len(self.job_lines),2)
                sum += line.cost
        left = self.order.amount_total-sum
        for line in self.job_lines:
            if line.state=='active' and not line.is_finish:
                line.cost+=left
                break

    @api.onchange('job_lines')
    def notify_pending(self):
        _logger.info("IN")
        self.to_pending = True

    @api.multi
    def write(self,val):
        _logger.info(val)
        super(JobContainer,self).write(val)
        _logger.info(str(val))
        if self.to_pending:
            _logger.info("INNNN")
            self.pending()
        return True

看看这个答案:

(0, 0,  { values })    link to a new record that needs to be created with the given values dictionary
(1, ID, { values })    update the linked record with id = ID (write *values* on it)
(2, ID)                remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)

Example:
[(0, 0, {'field_name':field_value_record1, ...}), (0, 0, {'field_name':field_value_record2, ...})]
