python - Odoo 按钮单击打开弹出窗口和其中的文本

Question

我的 Odoo 工作流程带有“取消”和“重置”按钮。我需要用户点击这些按钮可以添加一个原因。

为此，我找到了 sale_cancel_reason 应用程序。示例如下:

但我每次都需要写新的原因，而不是从列表中选择。我绑定(bind)了与向导的many2one关系，用户每次都可以在弹出的向导窗口上写下原因:

cancel_id = fields.Many2one('sale.order.cancel', string="Cancellation")

'sale.order.cancel' - 向导对象

但是后来我得到了错误:

    'Many2One relationships from non-transient Model to TransientModel are forbidden'
AssertionError: Many2One relationships from non-transient Model to TransientModel are forbidden

据我了解，我无法将 Many2one 关系与 wizzard 对象一起使用。但是我还能如何制作带有可写原因字段的弹出窗口呢？有什么办法可以做到这一点吗？

编辑sale_cancel_reason\wizard\cancel_reason_view.xml 文件并更改:

<field name="reason_id" widget="selection"/>

至

<field name="reason_id"/>

更新:

要在每次单击取消按钮时创建新原因，请使用此 sale_cancel_reason

changed reason_id (Many2one) to reason (Char)
