解决方法
Odoo定义了ir_actions_server_id字段（在ir.crom模型中），并将delegate属性设置为True（对应于_inherits），这意味着{{1} }字段在ir.actions.server模型中可用。
ir.cron字段是在mail模块中定义的（将其添加到模块依赖项）模块中，作为必填字段，默认情况下设置为activity_user_type，因此，使用默认实现。
您可以通过继承specific模型并更改必填字段的ir.actions.server属性（将其设置为default）来重现类似的错误。
以下代码将引发一个False
odoo.tools.convert.ParseError这也可能是由于重写class IrActionsServer(models.Model):
_inherit = 'ir.actions.server'
usage = fields.Selection(default=False)
方法并将create的值设置为另一个字段值，该值最终被评估为activity_user_type的结果。
