如何取消Odoo onchange上的One2many字段值

Question

我創建了一個模塊，以根據客戶向PO訂單行添加銷售訂單行。

Selecting customer

當我添加銷售訂單將在PO順序加入。

我試圖取消鏈接one2many領域的特定的ID。在圖片添加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) 

當我刪除order_ids，我想從ORDER_LINE取消關聯相關線（PO）

link_ids將持有order_ids當選擇，當ID從order_ids中移除它將從link_ids中移除。 u_ids將在刪除時保留order_id的其餘部分。

當我刪除從order_ids一個ID iwant從ORDER_LINE

斷開鏈接的相關線路，但我不能刪除它。

我有用戶[6,0，ids]方法來取代值，它不會工作在創建狀態。 請幫幫我。

Answer 1

對於現場你用來做關係： -

sale_order_id = fields.Many2one('sale.order', related='sale_order_line_id.order_id', string='Order', 
           store=False) 

請儘量給屬性ondelete =「瀑布」，改變路線爲： -

sale_order_id = fields.Many2one('sale.order', related='sale_order_line_id.order_id', string='Order', ondelete ='cascade' 
           store=False) 

如果你把這樣的，當相關銷售訂單被刪除時，具有關係記錄的one2many條目也將被刪除。這只是一個例子，你可以嘗試這種方式。 感謝

Answer 2

以下是在one2many

@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() 

刪除記錄一個共同的邏輯這是要刪除的訂單記錄通常的方式

Answer 3

對不起，我遲到了它是一個記錄時間：

嘗試使用[(5,0,0)]刪除每條記錄，然後添加ID。這工作對我來說，但唯一的問題是，它的工作，如果其他領域觸發onchange方法不相同many2many或one2many領域

但在創建模式，如果你沒有找到任何解決方案，爲什麼你不使用更新按鈕，當他在顯示one2many字段之前更改選定的訂單id時，他需要驗證，這樣您將一直在寫作，因爲創建將在驗證選擇時發生。我想說的是找到它的工作和工作，找到一種方法來使用它
