如何覆蓋one2many中的刪除按鈕從銷售訂單

in one2many行刪除按鈕是否存在當該行中的布爾值字段爲true時，該行不會刪除並引發異常。我喜歡以下代碼如何覆蓋one2many中的刪除按鈕從銷售訂單

但我不會影響代碼。沒有任何迴應行被刪除。請....告訴我任何一個

在此先感謝....

from odoo import api, models, fields, _, SUPERUSER_ID 
import string 
from odoo import exceptions 
from odoo.exceptions import ValidationError 


class ouc_sale_order(models.Model): 
    _inherit = 'sale.order' 
    c_state = fields.Selection(
     [("draft", "Draft Proforma Invoice"), ("sent", "Proforma Invoice Sent"), ("cancel", "Cancelled"), 
     ("waiting_date", "Waiting Schedule"), ("progress", "Sales Order"), ("manual", "Sale to Invoice"), 
     ("shipping_except", "Shipping Exception"), ("invoice_except", "Invoice Exception"), ("done", "Done")], 
     string='State') 


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

    c_status = fields.Selection([('New', 'New'), ('renewal', 'Renewal'), ('upgrade', 'Upgrade'), ('upsell', 'Upsell'), ('PDC', 'PDC'), 
     ('etc', 'etc')], string='Status', default='New') 
    c_fptags_id = fields.Many2one('ouc.fptag', string='FPTAGs') 
    c_product_template_id = fields.Many2one('product.template', string='Product Template', related='product_id.product_tmpl_id') 
    c_package_id = fields.Many2one('ouc.package', string='Packages') 
    c_pkg_expiry_in_month = fields.Integer(string='Package Expires After(Months)', related='c_package_id.validity') 
    c_subtotaltax = fields.Float('Subtotal with Tax') 
    c_taxamount = fields.Float('Tax Amount') 
    c_client_id = fields.Char('Client Id') 
    c_default_discount = fields.Float('Default Discount (%)') 
    c_max_discount = fields.Float('Maximum Discount (%)') 
    c_subscription_status = fields.Boolean(string='Subscription') 


#@api.multi 
#def unlink(self): 
# for record in self: 
#  if record.c_subscription_status: 
#   raise exceptions.ValidationError(_('You didn\'t delete this record')) 
# return super(ouc_sales_order_line,self).unlink()

您能否在此指定模型結構？ –

你的代碼似乎沒有問題。你能告訴我們你在模型中添加了這個方法嗎？ –

我已經在父類的comodel中添加了。在sale.order.line –

你工作的這段代碼！

剛剛做了一點修正>添加默認=假現場。（不是必要的，但好的做法！）

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

    c_subscription_status = fields.Boolean(string='Subscription', default=False) 

    @api.multi 
    def unlink(self): 
     for record in self: 
      if record.c_subscription_status: 
       raise ValidationError(_('You didn\'t delete this record')) 
     return super(ouc_sales_order_line, self).unlink()

獲取其中的布爾字段設置爲TRUE在ORDER_LINE刪除記錄和訂單>保存>它會引發驗證錯誤！
