Question

我将我的自定义字段添加到res.partner模型中，并且当我创建伙伴（如果选中branch_id时）时，我希望选择3个字段之一。如果未选择某些字段，那么我想引发UserError。

但是现在即使我选择了其中一个字段，它也会引发UserError。

class ResPartner(models.Model):
    _inherit = 'res.partner'

 branch_id = fields.Many2one('branch.responsibility','Responsibility by branch')
 drawer_id = fields.Many2one(
        'furniture.parts.type', string='Drawer Type',
        domain=[('type', '=', 'drawer')], )
flexible_id = fields.Many2one(
        'furniture.parts.type', string='Flexible Type',
        domain=[('type', '=', 'flexible')],)
 runner_id = fields.Many2one(
        'furniture.parts.type', string='Runner Type',
        domain=[('type', '=', 'runner')], )


@api.model
    def create(self, vals):
        if vals.get('branch_id'):
            if not vals['drawer_id'] or not vals['flexible_id'] or not vals['runner_id']:
                raise UserError('You need to chose values from notebook raport data')
        return super(ResPartner, self).create(vals)

更新。

对于写方法，我按照CZoellner建议的创建方法进行了尝试，但始终对fields_to_check_in_vals取True True True

 @api.multi
     def write(self, vals):
         if vals.get('branch_id') or vals.get('drawer_id') or vals.get('flexible_id') or vals.get('runner_id') or
 vals.get('group_1_id') or vals.get('group_2_id')or
 vals.get('group_3_id'):
             fields_to_check = ['drawer_id', 'flexible_id', 'runner_id', 'group_1_id', 'group_2_id', 'group_3_id']
             fields_to_check_in_vals = [f in self for f in fields_to_check]
             if not any(fields_to_check_in_vals):
                 raise UserError('If branch is selected then you need to select one of the fields from data raport')
>         return super(ResPartner, self).write(vals)

您的逻辑说，必须设置所有3个字段。您可以在此处使用any：

if vals.get('branch_id'):
    fields_to_check = ['drawer_id', 'flexible_id', 'runner_id']
    fields_to_check_in_vals = [f in vals for f in fields_to_check]
    if not any(fields_to_check_in_vals):
        raise UserError()

编辑：write方法比较棘手。通常，它是一种多记录方法，因此应实现针对self的每个循环。然后，您将需要使用getattr或仅（在Odoo文档中建议）将记录集视为dict。然后可能是更改直接发生在写调用上。因此，您必须检查持久值和新值：

for record in self:
    if vals.get('branch_id'):
        fields_to_check = ['drawer_id', 'flexible_id', 'runner_id']
        fields_to_check_dict = {f:record[f] for f in fields_to_check}
        fields_to_check_dict.update({f:f in vals for f in fields_to_check})
        if not any(fields_to_check_dict.values()):
            raise UserError()

有点复杂。您也可以先致电super，然后再检查。引发异常将回滚所有更改，因此不会发生任何事情。

res = super(MyModel, self).write(vals)
for record in self:
    if vals.get('branch_id'):
        fields_to_check = ['drawer_id', 'flexible_id', 'runner_id']
        fields_to_check_in_record = [record[f] for f in fields_to_check]
        if not any(fields_to_check_in_record):
            raise UserError()
return res

仅当未选择任何字段时才引发UserError
