Question

我在sale.order.line中有一个自定义字段

scheme = fields.Many2one('scheme')

与此相同，account.invoice.line中的字段也为

scheme = fields.Many2one('scheme')

将销售订单转换为发票时，我想将值从sale.order.line复制到account.inovice.line。我怎么能这样做？

我尝试在继承的类中覆盖函数（在单击创建发票按钮时调用），但该函数未执行。我怎么能这样做？

我试过这样的事情，但功能没有执行..

def _prepare_advance_invoice_vals(self, cr, uid, ids, context=None):
    ......
    .....

        # create the invoice
        inv_line_values = {
            'name': res.get('name'),
            'origin': sale.name,
            'account_id': res['account_id'],
            'price_unit': inv_amount,
            'quantity': wizard.qtty or 1.0,
            'discount': False,
            'uos_id': res.get('uos_id', False),
            'product_id': wizard.product_id.id,
            'invoice_line_tax_id': res.get('invoice_line_tax_id'),
            'account_analytic_id': sale.project_id.id or False,
            'scheme':sale.scheme,
        }
        inv_values = {
            'name': sale.client_order_ref or sale.name,
            'origin': sale.name,
            'type': 'out_invoice',
            'reference': False,
            'account_id': sale.partner_id.property_account_receivable.id,
            'partner_id': sale.partner_invoice_id.id,
            'invoice_line': [(0, 0, inv_line_values)],
            'currency_id': sale.pricelist_id.currency_id.id,
            'comment': sale.note,
            'payment_term': sale.payment_term.id,
            'fiscal_position': sale.fiscal_position.id or sale.partner_id.property_account_position.id,
            'section_id': sale.section_id.id,
            'scheme':sale.scheme,(custom field)
        }
        result.append((sale.id, inv_values))
    return_value = super(account_advance_inv, self)._prepare_advance_invoice_vals(result)
    return return_value

在销售模块中覆盖sale.py中的 _prepare_invoice_line 方法。

    @api.multi
    def _prepare_invoice_line(self, qty):
        ...

        ...
        res = {
            'name': self.name,
            'sequence': self.sequence,
            'origin': self.order_id.name,
            'account_id': account.id,
            'price_unit': self.price_unit,
            'quantity': qty,
            'discount': self.discount,
            'uom_id': self.product_uom.id,
            'product_id': self.product_id.id or False,
            'invoice_line_tax_ids': [(6, 0, self.tax_id.ids)],
            'account_analytic_id': self.order_id.project_id.id,
            'scheme' : self.scheme.id
        }
        return res

在res字典中添加您的字段，如上面的代码所示。
