find() public abstract static method
Creates an yii\db\ActiveQueryInterface instance for query purpose.
The returned yii\db\ActiveQueryInterface instance can be further customized by calling methods defined in yii\db\ActiveQueryInterface before one()
or all()
is called to return populated ActiveRecord instances. For example,
// find the customer whose ID is 1 $customer = Customer::find()->where(['id' => 1])->one(); // find all active customers and order them by their age: $customers = Customer::find() ->where(['status' => 1]) ->orderBy('age') ->all();
This method is also called by yii\db\BaseActiveRecord::hasOne() and yii\db\BaseActiveRecord::hasMany() to create a relational query.
You may override this method to return a customized query. For example,
class Customer extends ActiveRecord { public static function find() { // use CustomerQuery instead of the default ActiveQuery return new CustomerQuery(get_called_class()); } }
The following code shows how to apply a default condition for all queries:
class Customer extends ActiveRecord { public static function find() { return parent::find()->where(['deleted' => false]); } } // Use andWhere()/orWhere() to apply the default condition // SELECT FROM customer WHERE `deleted`=:deleted AND age>30 $customers = Customer::find()->andWhere('age>30')->all(); // Use where() to ignore the default condition // SELECT FROM customer WHERE age>30 $customers = Customer::find()->where('age>30')->all();
