How to find out that connected models are connected?

Question

css

Tell me how to find out that connected models are correctly connected via hasMany. For example: if there are user and product tables.
there is a connection between them

public  function getTovar(){
        return $this->hasMany(Tovar::className(), ['id' => 'userID']);
          }

I know that when the connection is created correctly, then when you make calls, $model=User::find()->all();
you can see the result in the form $model->tovar.
And how to see what data $model returns and is the connection set correctly?

Good morning.
What do you mean?
If you look in the documentation , you will find the following methods:
1) getRelatedRecords() - will return all model relationships
2) getRelation() - will return data for a single relationship, in your case$model->getRelation('tovar')
As usual, for example through print_r($model)orprint_r($model->attributes)
