我得到了错误

这是我的报告.py

            'get_shortage_lines': self.get_shortage_lines,
        })
    def has_shortage_so_lines(self, order_id):
        _logger.info("sale order id >>> : %r", order_id)
        lines_obj = self.get_shortage_so_lines(order_id)
        if lines_obj:
            return True
        return False

class report_shortage_xls(osv.AbstractModel):#(models.AbstractModel):
    _name = 'report.stock.report_shortage_xls'
    _inherit = 'report.abstract_report'
    _template = 'stock.report_shortage_xls'
    _wrapped_report_class = ShortageReport

有没有办法从odoo导出xls。非常感谢您的帮助。

Answer 1

确保在这里

_template = 'stock.report_shortage_xls'

它必须是带有报告名称的模块名称，您已经为 sale.order 创建了报告，并且您已经给出了库存模块名称，在您的情况下是否正确？
