TypeError: cannot convert dictionary update sequence element #0 to a sequence - Odoo v10 community migration

Question

我的模块从 Odoov8 迁移到 Ovoo10 社区时仍然存在一些错误

我有这个方法：

@api.model
def search_partner_seniat(self):
    """ Check vat of the partner and update iva rate
    """
    self.ensure_one()
    vat = self.vat.upper()
    res = {
        'name': _('The requested contributor does not exist'),
        'vat_subjected': False,
        'vat': vat,
        'wh_iva_agent': False,
        'wh_iva_rate': 0.0
    }

    if 'VE' in vat:
        vat = vat[2:]

    # assumption: both methods in new api style
    if self.env['res.partner'].check_vat_ve(vat):  # check_vat_ve() should be @api.model
        res = self.env['seniat.url']._dom_giver(vat)  # _dom_giver() should be @api.model
    self.write(res)

    return {
        'type': 'ir.actions.act_window',
        'res_model': 'search.info.partner.seniat',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': self.id,
        'views': [(False, 'form')],
        'target': 'new',
    }

我知道这是一个按钮，它应该（或者至少看起来）是 @api.multi，但是之前，当它是 @api.multi 时，Odoo 告诉我这个方法应该是 api.model 所以我改变了它。

我不知道，但现在，每次我点击它，它都会说：

TypeError: cannot convert dictionary update sequence element #0 to a sequence

有没有人能解释一下这个？

Answer 1

如果你想 return 来自 Buttons 方法的字典，那么你必须需要使它 @api.multi.

@api.multi
def search_partner_seniat(self):
    # do stuff
    return dict

这可能对您有所帮助。谢谢

Answer 2

使用@api.multi 而不是模型，并且您正在尝试用 null 写入记录 self.write(res)，而 @api.model 仅在您没有 id 的情况下使用关联当前记录。例如：在 Odoo 上创建方法

所以在这里我建议将代码更改为：使用如果 len(res): self.write(分辨率)
