$value | boolean | Whether to return the query results in terms of arrays instead of Active Records. |
return | $this | The query object itself |

Converts found rows into model instances.
protected array|yii\db\ActiveRecord[] createModels ( $rows ) | ||
$rows | array |
Finds records corresponding to one or multiple relations and populates them into the primary models.
public void findWith ( $with, &$models ) | ||
$with | array | A list of relations that this query should be performed with. Please refer to with() for details about specifying this parameter. |
$models | array|yii\db\ActiveRecord[] | The primary models (can be either AR instances or arrays) |
Specifies the relations with which this query should be performed.
The parameters to this method can be either one or multiple strings, or a single array of relation names and the optional callbacks to customize the relations.
A relation name can refer to a relation defined in $modelClass
or a sub-relation that stands for a relation of a related record.
For example, orders.address
means the address
relation defined
in the model class corresponding to the orders
relation.
The following are some usage examples:
// find customers together with their orders and country
Customer::find()->with('orders', 'country')->all();
// find customers together with their orders and the orders' shipping address
Customer::find()->with('orders.address')->all();
// find customers together with their country and orders of status 1
Customer::find()->with([
'orders' => function (\yii\db\ActiveQuery $query) {
$query->andWhere('status = 1');
},
'country',
])->all();
You can call with()
multiple times. Each call will add relations to the existing ones.
For example, the following two statements are equivalent:
Customer::find()->with('orders', 'country')->all();
Customer::find()->with('orders')->with('country')->all();
public $this with ( ) | ||
return | $this | The query object itself |
