Description

MANY-MANY relation management for Yii framework

#How to use this behavior

Firstly suppose you have classes Book, Author and BookAuthor. BookAuthor is map-table (many-many) for relation Book <-> Author.

Add alias "terrasoff-map-relation"

Yii::setPathOfAlias('terrasoff-map-relation', Yii::getPathOfAlias('vendor').'/terrasoff/yii/map-relations');

For example, u could add it to your config file.

Add interface and behaviors to your model

class Book extends CActiveRecord implements MapRelatedInterface
{
	...
	public function behaviors() {
		return array(
			...
			'RelationBehavior' => array(
				'class' => 'terrasoff-map-relation.MapRelationBehavior',
			),
			'activerecord-relation-behavior' => array(
				'class' => 'vendor.yiiext.activerecord-relation-behavior.EActiveRecordRelationBehavior'
			),
		);
	}
}

Create controller

Yii::import('terrasoff-map-relation.controllers.MapRelatedController');

class MyController extends MapRelatedController
{

	public $ownerClass = 'Book';
	public $relatedClass = 'Author';

}

View related models

To view existed relations we could simply use "list" view. Also you could delete relation using this view. For example in CDetailView:

<?php $this->widget('zii.widgets.CDetailView', array(
	'data'=>$model, // Book
	'attributes'=>array(
		'name',
		'created',
		array(
			'label' => 'authors',
			'type'=>'raw',
			'value'=>function($model) {
				return $this->renderPartial('terrasoff-map-relation.views.list', array(
					'owner'=>$model,
					'relation'=>'Author',
				),true);
			}
		),
	),
)); ?>

Add new relation

To add new relation we simply navigate to MyController/add:
