Phalcon Eager Loading
安装
突然发现 phalcon/incubator 中已经有了eager load
composer require phalcon/incubator
use Phalcon\Mvc\Model\EagerLoadingTrait
使用
<?php use Phalcon\Mvc\Model\EagerLoading\Loader, Phalcon\Mvc\Model\EagerLoading\QueryBuilder; $robotsAndParts = Robot::with('Parts'); // Equivalent to: $robots = Robot::find(); foreach ($robots as $robot) { $robot->parts; // $robot->__get('parts') } // Or $robot = Robot::findFirst()->load('Parts'); // Equivalent to: $robot = Robot::findFirst(); $robots->parts; // $robot->__get('parts') // Because Robot::find() returns a resultset, so in that case this is solved with: $robots = Loader::fromResultset(Robot::find(), 'Parts'); # Equivalent to the second example // Multiple and nested relations can be used too $robots = Robot::with('Parts', 'Foo.Bar'); // And arguments can be passed to the find method $robots = Robot::with('Parts', 'Foo.Bar', ['limit' => 5]); // And constraints $robots = Robot::with( [ 'Parts', 'Foo.Bar' => function (QueryBuilder $builder) { // Limit Bar $builder->limit(5); } ], [ 'limit' => 5 ] );
