ORM：发票 v10 中计算税的 v14 等价物是什么？

如何解决ORM：发票 v10 中计算税的 v14 等价物是什么？

V10 中函数 compute_taxes() 的 V14 等效项是什么，它在其他模块中用于计算创建的新发票的税费。 谢谢。

 def compute_taxes(self):
        """Function used in other module to compute the taxes on a fresh invoice created (onchanges did not applied)"""
        account_invoice_tax = self.env['account.invoice.tax']
        ctx = dict(self._context)
        for invoice in self:
            # Delete non-manual tax lines
            self._cr.execute("DELETE FROM account_invoice_tax WHERE invoice_id=%s AND manual is False",(invoice.id,))
            if self._cr.rowcount:
                self.invalidate_cache()

            # Generate one tax line per tax,however many invoice lines it's applied to
            tax_grouped = invoice.get_taxes_values()

            # Create new tax lines
            for tax in tax_grouped.values():
                account_invoice_tax.create(tax)

        # dummy write on self to trigger recomputations
        return self.with_context(ctx).write({'invoice_line_ids': []})

解决方法

是的，我看到 v14 中的架构“有点”改变（我只是比较了代码，但从未使用过 odoo）。

您现在正在寻找的是我相信 account_tax.py 文件中第 342 行的方法：

def compute_all(self,price_unit,currency=None,quantity=1.0,product=None,partner=None,is_refund=False,handle_price_include=True):
    """ Returns all information required to apply taxes (in self + their children in case of a tax group).
        We consider the sequence of the parent for group of taxes.
            Eg. considering letters as taxes and alphabetic order as sequence :
            [G,B([A,D,F]),E,C] will be computed as [A,F,C,G]

        'handle_price_include' is used when we need to ignore all tax included in price. If False,it means the
        amount passed to this method will be considered as the base of all computations.

    RETURN: {
        'total_excluded': 0.0,# Total without taxes
        'total_included': 0.0,# Total with taxes
        'total_void'    : 0.0,# Total with those taxes,that don't have an account set
        'taxes': [{               # One dict for each tax in self and their children
            'id': int,'name': str,'amount': float,'sequence': int,'account_id': int,'refund_account_id': int,'analytic': boolean,}],} ..."""

... 这个方法返回类似：

return {
    'base_tags': taxes.mapped(is_refund and 'refund_repartition_line_ids' or 'invoice_repartition_line_ids').filtered(lambda x: x.repartition_type == 'base').mapped('tag_ids').ids,'taxes': taxes_vals,'total_excluded': sign * total_excluded,'total_included': sign * currency.round(total_included),'total_void': sign * currency.round(total_void),}

所以我想如果你想实现一些自定义的东西，你需要改变这个方法。
