Creating model using DAO

Yii 1.1 General Discussion
1

Can someone explain it to me how to create DAO object in a model?

It’s only explained how to get the results, but not how to populate the attributes.

This is what I wrote, but I’m sure this is not the right way.

This is a model:


private $_cmdSelect;

public $user;


sql = 'SELECT * FROM periods WHERE user=:user LIMIT 1';

$this->_cmdSelect = Yii::app()->db->createCommand($sql);


$this->_cmdSelect->bindValue(':user', $this->user, PDO::PARAM_STR);

$this->_attributes = $this->_cmdSelect->queryRow();

Written on this way generally works. The problem is when I try to change the attribute value with this…


$this->someattr = something

…I get a fatal error “Call to a member function bindValue() on a non-object”. It works only in one model, but I don’t know why. By examining the model in a view file I noticed that I’m missing _schema:private value. I just don’t know how it gets populated…

Can somebody help me?

Thanks in advance!

To populate an actual model object, you can use CActiveRecord.populateRecord($array);


$model = new Model();

$user = $model->populateRecord($this->_attributes);
