Odoo AttributeError:类型对象“”没有属性“”

表单上有两个按钮用于切换所有记录是否完成，第二个按钮用于清除所有完成的记录，但它不起作用，但会生成错误 AttributeError:类型对象“todo.task”没有属性“do\u toggle\u done” 按属性残缺什么，如何为两个按钮添加残缺

这两个按钮都会出现错误

        (# -*- coding: utf-8 -*-
    from odoo import models, fields, api


    class TodoTask(models.Model):
        _name = 'todo.task'
        _description = 'To-do Task'

        name = fields.Char('Description', required=True)
        is_done = fields.Boolean('Done?')
        active = fields.Boolean('Active?', default=True)

        @api.multi
        def do_toggle_done(self):
            for task in self:
                task.is_done = not task.is_done
            return True

        @api.model
        def do_clear_done(self):
            dones = self.search([('is_done', '=', True)])
            dones.write({'active': False})
            return True

按钮调用与当前活动模型和记录集直接相关。您需要使用@api.multi来处理对象类型按钮。使用@api.multi decorators更改按钮方法。其他一切似乎都与您的代码很好。应该可以很好地工作。

尝试重新启动odoo并更新模块，它对我有效。

您是否重新启动并更新了模块？嗯，我没有看到您的代码中有任何错误。@WaKo是的，我有，并且附上了完整的错误消息。您的其他Python更改是否有效？例如更改字段标签或使字段成为必需字段？非常感谢，但是@api multi已经在代码@api multi--def to_toggle_done您在清单文件中添加了xml文件了吗？？也许文件不见了。@Jack，是的，我找到了
