Yii2 dynamic form constraint violation on unique index in database table - forms

Question

I am creating a form with dynamic fields in which 2 fields have unique indexes in the database table. 1st 'Landline' and 2nd 'Address'. If there is no duplicate value in any of the dynamically added fields then the form submits without any error, but if I enter Address or Landline which matches any previously added field then shows constraint violation instead of showing error message even when I have already added rules in the model.
For example: I have 1 record with address = 'address', landline = 123 and I create a new record with the address = 'address' or landline = 123 then there is no error but when I submit it shows:
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'
If I remove the indexes from the table then data saves successfully.
I have tried to submit this normally and via ajax but same problem every time, my main interest is submitting the form via ajax.
I already have googled for this issue, but couldn't find any solution, please help.

Answer 1

I think that $model->save(false) skip unique index validation.
