尝试转换发票中的订单时出错

当我在自定义字段“mode_reglement”中选择我想要发票（所有/百分比/等等）之后尝试转换发票中的订单时，我遇到了问题

我在开发环境中没有问题，但在 生产环境 中：跟踪：

当我想在手动发票中进行信用方时（而mode_reglement字段不为空且不为空），会出现类似的问题：

The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set
[object with reference: mode_reglement - mode.reglement]

我的代码：

class mode_reglement(osv.osv):
        _name = 'cap.mode_reglement'
        _columns = {
            'name' : fields.char('Nom',required=True),
            }


    class account_invoice(osv.osv):
        _inherit = 'account.invoice' 

        _columns = {
                'mode_reglement':fields.many2one('cap.mode_reglement','Mode de reglement',auto_join=True,required=True),
        }
