python - 类型错误 : __init__() takes exactly 2 arguments (3 given) - Odoo v8 to Odoo v10 community

Question

考虑这个函数:

@api.multi
def create_invoice(self):
    """ Create a invoice refund
    """

    self.ensure_one()
    if not self.sure:
        raise UserError(
            _("Validation error!"),
            _("Please confirm that you know what you're doing by"
              " checking the option bellow!"))
    if (self.invoice_id and self.invoice_id.company_id.jour_id and
            self.invoice_id and self.invoice_id.company_id.acc_id):
        inv_id = self.action_invoice_create(self,
                                            self.invoice_id) 
    else:
        raise UserError(
            _('Validation error!'),
            _("You must go to the company form and configure a journal"
              " and an account for damaged invoices"))
    return self.new_open_window([inv_id], 'action_invoice_tree1', 'account') 

这是我从 v8 社区迁移到 v10 社区的结果。

这个方法原来是这样的:

def create_invoice(self, cr, uid, ids, context=None):
    """ Create a invoice refund
    """
    context = context or {}
    wizard_brw = self.browse(cr, uid, ids, context=context)
    inv_id = context.get('active_id')
    for wizard in wizard_brw:
        if not wizard.sure:
            raise osv.except_osv(
                _("Validation error!"),
                _("Please confirm that you know what you're doing by"
                  " checking the option bellow!"))
        if (wizard.invoice_id and wizard.invoice_id.company_id.jour_id and
                wizard.invoice_id and wizard.invoice_id.company_id.acc_id):
            inv_id = self.action_invoice_create(cr, uid, ids, wizard,
                                                wizard.invoice_id, context)
        else:
            raise osv.except_osv(
                _('Validation error!'),
                _("You must go to the company form and configure a journal"
                  " and an account for damaged invoices"))
    return self.new_open_window(cr, uid, ids, [inv_id],
                                'action_invoice_tree1', 'account')

此方法检查字段 acc_id 和 jour_id 是否在 company_id 上指定。

现在，它抛给我这个:

对此有什么想法吗？

Answer 1

你得到错误是因为 UserError 只接受一个参数，而你传递了两个参数。

你需要使用ValidationError

Odoo 主要提供三种类型的异常警告。

1.用户错误

2.重定向警告

3.验证错误

UserError & ValidationError 只接受一个参数，并且只在向导头消息中有所不同。

例如:

  raise ValidationError(_('A transaction can\'t have a 0 amount.'))

  raise UserError(_('Error In Input Data'))

RedirectWarning 接受三个参数。

  raise RedirectWarning(msg, action.id, _('Go to the configuration panel'))

第一个 参数是错误消息。

第二个重定向操作参数，您可以在配置屏幕中单击链接和重定向。

第三个参数是导航消息。
