我正在创建一个包含动态字段的表单，其中2个字段在数据库表中具有唯一索引。第一个“固定电话”和第二个“地址”。如果任何动态添加的字段中没有重复值，则表单提交时没有任何错误，但如果我输入匹配任何先前添加的字段的地址或固定电话，则显示约束违规，而不是显示错误消息，即使我已经添加了规则在模型中。
例如：我有1条记录，地址='地址'，固定电话= 123，我创建了一条地址='地址'或固定电话= 123的新记录，然后没有错误，但是当我提交时显示：< / p>
Exception (Integrity constraint violation) 'yii\db\IntegrityException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '15-address' for key 'unique_doctors_id__address'
如果从表中删除索引，则数据会成功保存。
我试图正常提交这个并通过ajax但每次都有相同的问题，我的主要兴趣是通过ajax提交表单。
我已经搜索了这个问题，但找不到任何解决方案，请帮忙。

我认为$model->save(false)会跳过唯一索引验证。
