我创建了一个模块，根据客户向PO订单行添加销售订单行。
当我添加销售订单时，它将按订单顺序添加。
我试图取消特定ID与one2many字段的链接。在图片中添加SO字段
class PurchaseOrder(models.Model):
_inherit= "purchase.order"
_name = "purchase.order"
order_ids = fields.Many2many('sale.order', String="Add Order",domain="[('partner_id', 'child_of', partner_id),('state', 'in', ('quotation','socreated','done'))]")
@api.onchange('order_ids')
def orders_change(self):
if not self.order_ids:
return {}
if not self.partner_customer_id:
warning = {
'title': _('Warning!'),
'message': _('You must first select a partner!'),
}
# self.order_ids =False
return {'warning': warning}
line_ids = []
u_ids=[]
new_lines = self.env['purchase.order.line']
for qt in self.order_ids:
for i in self.order_line.mapped('sale_order_id'):
line_ids.append(i)
for u in self.order_ids:
if u.id in line_id:
u_ids.append(u)
line_ids.remove(u)
if line_ids and u_ids:
lp = self.order_line.filtered(lambda r: r.sale_order_id <= line_ids[0])
lp2 = self.order_line.filtered(lambda r: r.sale_order_id <= u_ids[0])
for line in self.order_line:
if line in lp:
# self.order_line = [(6, 0, lp2.ids)]
line.unlink()
continue
for line in qt.order_line:
# Load a PO line only once
if line in self.order_line.mapped('sale_order_line_id'):
continue
#seller section
seller = line.product_id._select_seller(
line.product_id,
partner_id=self.partner_id,
quantity=line.product_uom_qty,
date=self.date_order and self.date_order[:10],
uom_id=line.product_uom)
price_unit = self.env['account.tax']._fix_tax_included_price(seller.price,
line.product_id.supplier_taxes_id,
line.tax_id) if seller else 0.0
if price_unit and seller and self.currency_id and seller.currency_id != self.currency_id:
price_unit = seller.currency_id.compute(price_unit, self.currency_id)
if seller and line.product_uom and seller.product_uom != line.product_uom:
price_unit = self.env['product.uom']._compute_price(seller.product_uom.id, price_unit,
to_uom_id=line.product_uom.id)
unit = price_unit
qty = line.product_uom_qty
if float_compare(qty, 0.0, precision_rounding=line.product_uom.rounding) <= 0:
qty = 0.0
tax_id = line.tax_id or line.product_id.taxes_id
data = {
'sale_order_line_id': line.id,
'name': line.name,
'sequence_number':line.sequence_number,
'product_id': line.product_id.id,
'product_qty': qty,
'product_uom': line.product_id.uom_po_id or line.product_id.uom_id,
'price_unit': unit,
'cpo_no' : line.order_id.cpo_number,
'cpo_product_qty': qty,
'cpo_product_uom': line.product_id.uom_id,
'cpo_price_unit': line.price_unit,
'discount': 0.0,
'date_planned':(datetime.today() + relativedelta(weeks=4)).strftime(DEFAULT_SERVER_DATETIME_FORMAT),
}
new_line = new_lines.new(data)
new_line._set_additional_fields(self)
new_lines += new_line
if new_lines :
self.order_line += new_lines
class PurchaseOrderLine(models.Model):
_inherit= "purchase.order.line"
_name = "purchase.order.line"
sale_order_line_id = fields.Many2one('sale.order.line', 'Order Line', ondelete='set null', select=True
)
sale_order_id = fields.Many2one('sale.order', related='sale_order_line_id.order_id', string='Order',
store=False)
当我删除order_ids时，我想取消关联order_line（po）
中的相关行
link_ids会在选中时保存order_ids，当从order_ids中删除ID时，它将从link_ids中删除。 删除时，u_ids将保留order_id的其余部分。
当我从order_ids中删除id时，我想取消相关行与order_line的链接
但我无法将其删除。
我有用户[6,0，ids]方法来替换值，它不会在创建状态下工作。 请帮帮我。

以下是删除one2many中记录的常用逻辑
@api.onchage('field_name')
def onchange_field_name(self):
for line in self.one2many_field_records:
if line.order_id == 'your_satisfying_condition':
line.unlink()
这是删除订单行记录的常用方法

对不起，我已经迟到了。
尝试使用[(5,0,0)]删除所有记录，然后添加ID。这对我有用，但唯一的问题是，如果其他字段触发onchange方法不是相同的many2many或one2many字段，它可以工作
但是在创建模式下，如果您没有找到任何解决方案，为什么在更改所选订单ID时不使用更新按钮，他需要在显示one2many字段之前进行验证，这样您就可以使用写总是因为当他验证选择时会发生创建。我试图说的是找到它的工作方式，并找到一种方法来使用它
答案 2 :(得分：0)
对于你曾经建立关系的领域： -
sale_order_id = fields.Many2one('sale.order', related='sale_order_line_id.order_id', string='Order',
store=False)
请尝试给出属性ondelete =＆＃39; cascade＆＃39;并将行更改为： -
sale_order_id = fields.Many2one('sale.order', related='sale_order_line_id.order_id', string='Order', ondelete ='cascade'
store=False)
如果你这样说，当相关的销售订单被删除时，带有关系记录的one2many条目也将被删除。这只是一个例子，您可以尝试这种方式。 感谢
