Odoo v9如何将数字金额转换为文本金额

Question

我想将总金额转换为发票中的字母，为此我使用了amount_to_text函数，但它不起作用，什么都没有显示，这是我的代码

account_invoice.py (C：\Program Files (x86(\Odoo 9.0-20170309\server\openerp\addons\account\models\account_invoice.py

@api.multi
    def onchange_amount(self, amount_total):
        x_Montant = amount_to_text_fr.amount_to_text(amount_total, 'fr', 'DZ')
        return  {'x_Montant': x_Montant}

我在 C：\Program Files (x86(\Odoo 9.0-20170309\server\openerp\addons\account\views\account_invoice_view 中调用此函数

<record id="invoice_form" model="ir.ui.view">

Answer 1

在 odoo 的 9.0 版中，要创建一个更改方法，您必须执行此操作

蟒蛇文件

@api.onchange(amount_total)
def onchange_amount(self):
    self.x_Montant = amount_to_text_fr.amount_to_text(self.amount_total, 'fr', 'DZ')

XML 文件

**<field name="amount_total" class="oe_subtotal_footer_separator" /> **

Answer 2

在 openerp 中，如果您在 XML 字段(旧 api(中定义 onchange 方法：

def onchange_field(self, cr, uid, record_ids, record_id, context=None):
        # compute value...
        return {'value': {'field_name': value, 'other_field_name':value2}}

但在新的 API 中使用装饰器 api.onchange

@api.onchange
def onchange_field(self):
            # compute value...
            self.field_name = value
            self.other_field_name  = value2
