如何在odoo中将一个字段的值复制到另一个字段？
我在product.template模块中创建了自定义字段折扣，现在我想复制并将其分配给销售模块中的折扣字段。我想在发票中输入其名称，价格和折扣价值后自动折扣。我正在创建发票中的创建和编辑选项创建产品。如果我在选择产品后再次为同一产品生成发票，则应自动应用其折扣。我尝试使用其中一个从互联网获得的代码自动折扣，但产品描述和价格价值消失了。 discount是sales模块中的一个字段，x_discount是products模块中的一个字段，我想将x_discount值复制到discount，因为它们在不同的模块中我觉得很难。
dis = self.pool.get('product.template').browse(cr, uid,product,context=context).x_discount
return {'value': {'discount':dis}}

答案 0 :(得分：3)
您必须使用 onchange ： -
＆＃34; onchange ＆＃34;只要用户填写了字段中的值，而不向数据库保存任何内容，机制就为客户端界面提供了一种更新表单的方法。
这里已经有了product_id的onchange： -
要实现此目的，您必须覆盖 sale.order.line 中的 product_id_change（）。
为此，您必须继承 sale.order.line 对象并通过添加以下行重新定义 product_id_change（）： - （在定义 product_obj之后的行之后） ）
result['discount'] = product_obj.x_discount
如需更多帮助： - 如果您使用v7将此代码复制到模块.py文件中： -

详细步骤： -
我们正在为此创建自己的自定义模块（最佳和推荐方式）： -
创建一个名为＆＃34; product_custom＆＃34;的文件夹。以下文件： -
__init__.py
__openerp__.py
product_custom.py
product_custom_view.xml
init文件内容： -
import product_custom
openerp文件内容： -
{
'name': "Product Customization",
'version': '1.0',
'depends': ['base','product','sale'],
'author': "Baiju KS",
'category': 'Customization',
'description': """

然后将此文件复制到addons文件夹并重新启动服务器， 之后更新模块列表并安装自定义模块。
希望这有帮助。
