按钮上的Odoo单击打开弹出窗口并在其中显示文本

Question

我正在使用取消和重置按钮的Odoo工作流程。我需要用户点击这些按钮可以添加原因。

为此，我找到了sale_cancel_reason个应用。示例：

但我每次都需要写出新的理由，而不是从列表中选择。 我和wizzard建立了很多关系，每次用户都可以在popup wizzard窗口上写出原因：

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

'sale.order.cancel' - wizzard对象

但后来我收到了错误：

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

据我所知，我不能使用与wizzard对象的Many2one关系。但是我怎么能用可写原因字段制作弹出窗口呢？有没有办法做到这一点？

Answer 1

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

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

到

<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

  

将reason_id（Many2one）更改为reason（字符）
