仅当 none 个字段被选中时引发 UserError

Question

我将我的自定义字段添加到 res.partner 模型，当我创建合作伙伴时，如果选中 branch_id，我想选择 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 write 方法，我按照 CZoellner 建议的创建方法进行了尝试，但对于 fields_to_check_in_vals

总是得到 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)

按照您的逻辑，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 方法有点棘手。通常它是一个多记录方法，因此应该为自己实现一个 for each 循环。然后您需要使用 getattr 或只是（在 Odoo 文档中建议）将记录集视为字典。然后可能是，更改发生在写入调用上。所以你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()

这有点复杂。您也可以先调用 super 然后再检查。引发异常将回滚所有更改，因此什么都不会发生。

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 none 个字段被选中时引发 UserError

Raise UserError only if none fields selected
