python - 如何在 Odoo 中将值和翻译从一个字段复制到另一个字段？

Question

想象一下您想要填写 sale.order 中的一个字段。带有默认值的表单，Odoo 中使用的每个公司都将使用相同的文本。有时，通常的方法是使用 res.company 中的公共(public)字段。模型。其他选项是在 res.partner 中添加一个填充一些其他内容的字段。当选择客户时。

但我发现的问题是:如果我想获取该字段的翻译(这些翻译已经在原始字段中)，我必须手动执行此操作，继承 ir.translation 的 create 方法。当该字段复制到sale.order时创建了当前使用的语言的记录，因此我利用它来创建其余的记录。有更好的方法吗？

此外，我想补充一点，保存记录后，我按世界图标再次翻译文本，会使用当前文本创建新翻译。所以我需要在每个sale.order上再次翻译所有内容。记录一下。

我在 ir.translation 中执行了此操作简单文本字段的模型，以便创建其余语言的翻译。领域field_to_translate双面均可翻译:

@api.model
def create(self, vals):
    record = super(IrTranslation, self).create(vals)
    name = vals.get('name', False)  # name of the field to translate
    lang = vals.get('lang', False)  # creating record for this language
    if 'context' in dir(self.env):
        cur_lang = self.env.context.get('lang', False)  # current used language
        if name == 'sale.order,field_to_translate' and lang == cur_lang:
            langs = self.env['ir.translation']._get_languages()
            langs = [l[0] for l in langs if l[0] != cur_lang]   # installed languages

            for l in langs:
                if self.env.user.company_id.field_to_translate:
                    t = self.env['ir.translation'].search([
                        ('lang', '=', l),
                        ('type', '=', 'model'),
                        ('name', '=', 'res.company,field_to_translate')
                    ])
                    if t:
                        self.env['ir.translation'].create({
                            'lang': l,
                            'type': 'model',
                            'name': 'sale.order,field_to_translate',
                            'res_id': record.res_id,
                            'src': record.src,
                            'value': t.value,
                            'state': 'translated',
                        })

啊，我想这样做是因为我想将它们打印在不同的报告上。这些报告的语言将取决于客户lang字段。

简而言之，如何在 res.company 中设置可翻译字段作为 sale.order 中其他字段的默认值模型？其他语言的翻译也应该复制。我上面的建议有点麻烦

好吧，最后我在 sale.order 的 create 方法中创建了翻译。我使用了 ir.translation 模型的自定义 translate_fields 方法来自动创建翻译，然后使用正确的语言翻译手动更新所有值。

另一方面，我在 l10n_multilang 模块中发现了这个类，它对于可能发现相同问题的其他人很有用:
