Yii Framework-将字段从其他表存储到模型中

Question

I need some help with the Yii 2.x framework.

I have 2 tables, stuff and table , each with their own models, Stuff and Table .

stuff and table share a key. stuff contains table_id which links to id in table .

The stuff controller contains the following code to retrieve all fields from stuff and the age field from table :

$model = Stuff::find ()
                ->select (['`stuff`.*', '`table`.`age`'])
                ->leftJoin ('table', '`stuff`.`table_id`=`table`.`id`', [])
                ->where (['table_id' => $id])
                ->one ()

Once executed, $model contains everything from the stuff table, but does not contain the age field, even though the generated SQL does retrieve it. I have found that adding public $age; into the Stuff model does store the age field, however this seems like a hack and feels dirty.

So my question is, is it possible to get the $model variable to store fields from a referenced table without altering the original model? If that's not possible, is there a more correct way of doing things than what I have already done?

Thanks!

Answer 1

You can access related model fields in the object oriented fashion, something like this:

$model->table->age

In the above expression, table is relation name in the Stuff model.

Answer 2

Define relation in the stuff model like this

public function getTable()
{
    return $this->hasOne(Table::className(), ['id' => 'table_id']);
}

and then you can access it via referenced object like

$model->table->age
