Openerp 将引用字段添加到视图的上下文中

我在模型中有一个参考字段

ref = fields.Reference ....

---

我将其添加到树视图的搜索视图中，当我尝试将此字段添加到上下文中以使用

search\u default\u ref:'sale.order，1'

打开视图时，它将被忽略，不会添加到搜索字段中。

该字符串必须与引用字段内容匹配：

{'search_default_ref': 'SO0001'}

如果要搜索记录id，应使用：

{'search_default_id': 1}

或者更好地使用相应的XML Id，例如：

{'search_default_id': ref('sale.sale_order_1')}

它向我显示了这个错误：Odoo客户端错误Uncaught TypeError:callable.\uuu call\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。
