Question

为什么它给我这样的错误我只是更新简单的字典。没有request.session它工作正常，但它在更新request.session时生成此错误。

   @api.multi
    def graph_view(self):
        vals = {}
        if self.x_axis and self.y_axis and self.range_period and self.range_selection:
            vals.update({'id': self.id,
                         'x_axis': self.x_axis,
                         'y_axis': self.y_axis,
                         'range_period': self.range_period,
                         'range_selection': self,
                         'graph_type': 'pie',
                         'model': self
        else:
            raise Warning('Please check the graph') 
        request.session.update(vals)
        res = self.env['ir.model.data'].get_object_reference('pan_pos', 'graph_form_view')
        return {
            'view_type': 'form',
            'view_mode': 'form',
            'view_id': res[1],
            'res_model': 'report.sales',
            'type': 'ir.actions.act_window',
            'target': 'current'
        }

PicklingError: Can't pickle <class 'openerp.api.sales'>: it's not found as openerp.api.sales

请帮我解决。感谢。

字典

包含错误的值，self给出了模型对象，如果没有找到记录则只给出对象模型，并且由于pickle对象不能支持模型类型对象而给出了pickle错误。

通过类型转换将字符串转换为对象模型。解决错误。

为什么Odoo在更新request.session时给出PicklingError
