如何关联国家和发票以打印自定义文本？

问题描述

在发票视图中，我有一个自定义布尔字段和一个自定义文本字段。

我正在尝试在报告中打印我的自定义字段的文本，但只有当发票将转到国家/地区组时，我才知道它的 ID。 我该如何做这个功能？ 如何关联国家/地区和发票以创建此功能？

解决方法

最简单的方法是在账户发票模型中添加一个函数并从qweb报告中调用它。您可以定义一个 qweb report parser 并在那里定义它，以便它在报告上下文中可用。

示例

我想国家组的定义如下：

class CountryGroup(models.Model):
    _name = 'country.group'

    name = fields.Char()
    country_ids = fields.Many2many("res.country")

您只需要在帐户发票模型中定义一个函数来返回特定国家/地区组的国家/地区 ID：

class AccountInvoice(models.Model):
    _inherit = 'account.invoice'

    def country_group_country_ids(self,group):
        return self.env['country.group'].search([('name','=',group)]).mapped('country_ids.id')

以下代码扩展了发票报告并在发票状态之后显示参考字段以供演示：

<template id="report_invoice_document" inherit_id="account.report_invoice_document">
    <xpath expr="//h2" position="after">
        <t t-if="o.partner_id.country_id and o.partner_id.country_id.id in o.country_group_country_ids('export')">
            <p t-field="o.reference"/>
        </t>
    </xpath>
</template>
