創建繼承覆蓋odoo

Question

我正在嘗試使用odoo 10進行覆蓋，事實是我想向odoo的現有方法添加功能，但我不知道該怎么做，我已經添加了高級功能，但是行為不適當

驗證odoo底部的原始方法：

@api.multi
def action_invoice_open(self):
    # lots of duplicate calls to action_invoice_open, so we remove those already open
    to_open_invoices = self.filtered(lambda inv: inv.state != 'open')
    if to_open_invoices.filtered(lambda inv: inv.state not in ['proforma2', 'draft']):
        raise UserError(_("Invoice must be in draft or Pro-forma state in order to validate it."))
    to_open_invoices.action_date_assign()
    to_open_invoices.action_move_create()
    return to_open_invoices.invoice_validate()

我想將此代碼添加到此函數：

print('enter')
        Replique = self.env['dues.replique'] 
            new = Replique.create({
                    're_customer': self.partner_id.id,
                    'amount_invoice':self.amount_total,
                    'amount_total':self.t_invoice_amount,
                    'n_invoice' : self.number,
                })

而且我這樣做是這樣的：

class AddFields(models.Model):
    _inherit = "account.invoice"

    @api.model
    def action_invoice_open(self):
        print('enter')
        Replique = self.env['dues.replique'] 
            new = Replique.create({
                    're_customer': self.partner_id.id,
                    'amount_invoice':self.amount_total,
                    'amount_total':self.t_invoice_amount,
                    'n_invoice' : self.number,
                })
        campus_write = super(AddFields,self).action_invoice_open()
        return campus_write

但是錯誤是，現在僅執行我添加的新代碼，並且不執行原始方法的代碼，我不知道如何編輯該方法而不是完全取消該方法。

您的方法還不錯；-)

origin方法使用api.multi作為裝飾器，請勿在擴展名中進行更改。 api.model將使其成為非實例/記錄集方法，因此超級調用將使用空記錄集完成，這將導致未進行任何驗證。

另外：您的擴展程序僅在將驗證一張發票的情況下起作用。 但是，一張以上的發票會怎樣？ 這將引發“預期的單例”錯誤，因為self不會是Singleton 。

因此，只需將其更改為循環：

@api.multi  # don't change it to another decorator
def action_invoice_open(self):
    Replique = self.env['dues.replique']
    for invoice in self:
        Replique.create({
            're_customer': invoice.partner_id.id,
            'amount_invoice':invoice.amount_total,
            'amount_total':invoice.t_invoice_amount,
            'n_invoice' : invoice.number,
        })
    result = super(AddFields, self).action_invoice_open()
    return result
