Yii2 why can't get related data?

Question

Yii

Hello! For some reason, I can't get the associated data. There are 2 Post models
:

....
    public function getUser() {
      return $this->hasOne(User::className(), ['id' => 'author_id']);
    }

    public function getLikes() {
      return $this->hasMany(PostLikes::className(), ['like_id' => 'post_id']);
    }

and post likes

public function getPost() {
      return $this->hasOne(Posts::className(), ['post_id' => 'like_id']);
    }

Posts with User are fine, but Posts->likes stubbornly returns emptiness. What's wrong?

How do you know what's wrong? Where is the structure of tables or entities? Maybe you configured the connection incorrectly? Maybe there is no such ID!
Most likely so. Swap the IDs, but without the structure, you can't say:

public function getLikes() {
      return $this->hasMany(PostLikes::className(), ['post_id' => 'like_id']);
    }
