This article describes how to add default values to the model of yii, and describes how to set the following two implementation methods in the rules () method and the beforeSave () method, for more information about how to add default values to a model in yii, see the following example. We will share this with you for your reference. The details are as follows:

Yii model inherits from CActiveRecord

Some fields may not appear in the form, but must be added to the program. Such as the order number, timestamp, and user_id of the operation.

You can use either of the following methods:

1. Set in the rules () method:

public function rules(){  // NOTE: you should only define rules for those attributes that  // will receive user inputs.  return array(    array('start, end', 'required'),    array('user_id', 'numerical', 'integerOnly'=>true),    array('timestamp','default','value'=>date('Y-m-d H:i:s')),    // The following rule is used by search().    // Please remove those attributes that should not be searched.    array('id, start, end, user_id, timestamp', 'safe', 'on'=>'search'),  );}

2. Set in the beforeSave () method:

function beforeSave(){  $this->user_id = Yii::app()->user->id;  return true;}

Note that the beforeSave () method must return true, otherwise it will not be saved.
