How to display records in yii grid, only those that have related data?

Question

Yii

Good afternoon,
There is such a problem, when adding a certain application, several people can hang themselves on it, or maybe not hang themselves. I want the controller's actionAdmin grid to display only records that have links to persons.
Structure :
Bids
-------
id
-------
Livings
--------
person_id
bid_id
_ _ _ _ _ _ _ _

You can make a separate model for this.
You can specify the rules when forming the activedataprovider, through join, for example
