Yii范围与多表关系

Question

I have a model Order with one-to-many relationship to model Booking. Booking model, in turn, has a Connection model reference.

I'm having trouble figuring out how to scope out Order so that I only get the order that have bookings with Connection.isDefault value set to 0.

I may have many Bookings with the Order, so I need to look through the very first booking.

I feel this may not be achievable through the scope mechanism as I cannot pass Order/Booking primary keys through helper functions that can be used in scope. What is an alternative workaround here (if any) can you suggest?

The Order has a code for scopes: public function scopes() { return array( 'canView' => array( 'with' => array( 'agency' => array( 'scopes' => array('myNetwork', 'myCompany' => 'OR') ) ), ), 'canEdit' => array( 'with' => array( 'agency' => array( 'scopes' => array('myNetwork', 'myCompany' => 'OR') ), ), ), ); }

Answer 1

Please try using CDbCriteria(). add relation in Bookings table and order table.

The Bookings has a code for relation:

class Bookings extends CActiveRecord{

    public function relations() {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.

        return array(
            'connectionRel' => array(self::BELONGS_TO, 'connection', 'booking_id', "condition" => 'isDefault = 0'),
        );
    }
}

The Order has a code for relation:

class Order extends CActiveRecord{

    public function relations() {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.

        return array(
            'bookingsRel' => array(self::BELONGS_TO, 'Bookings', 'booking_id', "with" => array('connectionRel')),
        );
    }
}

Find all order with booking relation :

Order::model()->with('bookingsRel')->findAll();
