yii implements the method of adding default value to model (2 methods), yiimodel

This article describes the example of yii implementing the method of adding default value to model. Share it with everyone for your reference, the details are as follows:

yii model inherits from CActiveRecord

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

The following two 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;
}

It should be noted that the beforeSave() method needs to return true, otherwise will not be saved.
