Hi,
I try to filter query results with relationship. I have Comment and Post models with hasOne relation (Comment belongs to Post, and Post hasMany Comments).
With request I would like show all comments that belongs to post with id=10.
In comment controller I use IndexAction class to define actionIndex with dataFilter defined yii\data\ActiveDataFilter class.
I try to use request
comments/index?filter[post.id]=10&include=post
but post.id is converted to post_id and in SQL I have error, that post_id field is not defined.
How can I use filter by related table?
Big thanks for help!
