Property Details

baseLimited property (available since v1.0.2)
public boolean $baseLimited;

whether the base model has limit or offset. This property is internally used.

joinAll property (available since v1.0.2)
public boolean $joinAll;

join all tables all at once. Defaults to false. This property is internally used.

Method Details

__construct() method
public void __construct(CActiveRecord $model, mixed $with)
$model CActiveRecord the model that initiates the active finding process
$with mixed the relation names to be actively looked for

Constructor. A join tree is built up based on the declared relationships between active record classes.

count() method (available since v1.0.3)
public void count($condition='', $params=array ( ))
$condition
$params

This is the relational version of CActiveRecord::count().

find() method
public void find($condition='', $params=array ( ))
$condition
$params

This is the relational version of CActiveRecord::find().

findAll() method
public void findAll($condition='', $params=array ( ))
$condition
$params

This is the relational version of CActiveRecord::findAll().

findAllByAttributes() method
public void findAllByAttributes($attributes, $condition='', $params=array ( ))
$attributes
$condition
$params

This is the relational version of CActiveRecord::findAllByAttributes().

findAllByPk() method
public void findAllByPk($pk, $condition='', $params=array ( ))
$pk
$condition
$params

This is the relational version of CActiveRecord::findAllByPk().

findAllBySql() method
public void findAllBySql($sql, $params=array ( ))
$sql
$params

This is the relational version of CActiveRecord::findAllBySql().

findByAttributes() method
public void findByAttributes($attributes, $condition='', $params=array ( ))
$attributes
$condition
$params

This is the relational version of CActiveRecord::findByAttributes().

findByPk() method
public void findByPk($pk, $condition='', $params=array ( ))
$pk
$condition
$params

This is the relational version of CActiveRecord::findByPk().

findBySql() method
public void findBySql($sql, $params=array ( ))
$sql
$params

This is the relational version of CActiveRecord::findBySql().

lazyFind() method
public void lazyFind(CActiveRecord $baseRecord)
$baseRecord CActiveRecord the base record whose related objects are to be loaded

Finds the related objects for the specified active record. This method is internally invoked by CActiveRecord to support lazy loading.

together() method (available since v1.0.2)
public CActiveFinder together(boolean $ignoreLimit=true)
$ignoreLimit boolean whether we should enforce join even when a limit option is placed on the primary table query. Defaults to true. If false, we would still use two queries when there is a HAS_MANY/MANY_MANY relation and the primary table has a LIMIT option. This parameter is available since version 1.0.3.
{return} CActiveFinder the finder object

Uses the most aggressive join approach. By default, several join statements may be generated in order to avoid fetching duplicated data. By calling this method, all tables will be joined together all at once.
