[RESOLVED] Unable to generate a join on 3 tables

Hello everybody,

I apologize for my English but I’m French and I have not mastered much English !

I would create a database :

  • Table "animes"(cartoons in english) can have several type (for exemple : Action - adventure) who are in the table "animes_genres"

  • Table "animes_genres" can have serveral cartoons (who are in the table "animes")

When I use yiic for generate a model :

and here is the source php generate :


<?php


class animes_has_animes_genres extends CActiveRecord

{

	/**

	 * The followings are the available columns in table 'animes_has_animes_genres':

	 * @var integer $animes_id

	 * @var integer $animes_genres_id

	 */


	/**

	 * Returns the static model of the specified AR class.

	 * @return animes_has_animes_genres the static model class

	 */

	public static function model($className=__CLASS__)

	{

		return parent::model($className);

	}


	/**

	 * @return string the associated database table name

	 */

	public function tableName()

	{

		return 'animes_has_animes_genres';

	}


	/**

	 * @return array validation rules for model attributes.

	 */

	public function rules()

	{

		// NOTE: you should only define rules for those attributes that

		// will receive user inputs.

		return array(

			array('animes_id, animes_genres_id', 'required'),

			array('animes_id, animes_genres_id', 'numerical', 'integerOnly'=>true),

			// The following rule is used by search().

			// Please remove those attributes that should not be searched.

			array('animes_id, animes_genres_id', 'safe', 'on'=>'search'),

		);

	}


	/**

	 * @return array relational rules.

	 */

	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(

		);

	}


	/**

	 * @return array customized attribute labels (name=>label)

	 */

	public function attributeLabels()

	{

		return array(

			'animes_id' => 'Animes',

			'animes_genres_id' => 'Animes Genres',

		);

	}


	/**

	 * Retrieves a list of models based on the current search/filter conditions.

	 * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.

	 */

	public function search()

	{

		// Warning: Please modify the following code to remove attributes that

		// should not be searched.


		$criteria=new CDbCriteria;


		$criteria->compare('animes_id',$this->animes_id);


		$criteria->compare('animes_genres_id',$this->animes_genres_id);


		return new CActiveDataProvider('animes_has_animes_genres', array(

			'criteria'=>$criteria,

		));

	}

}

?>

Relation is empty !!!!

When a I use yiic for generate CRUD :

What can I do to solve this problem ?

if you want to use CRUD, you should create the table animes_has_animes_genres like that:

id

animes_id

animes_genders_id

And make id primary key. Once you generated the model you can even delete the id and redo the table as it was.

Personally I use id field.

Thanks for your fast reply.

My topic si now resolved :)
