如何在不调用控制器的情况下在模型中执行函数，YII 框架 [英] how to make a function execute in model without calling in controller ,YII framework

问题描述

在我基于 yii 的示例项目中，我有一个名为 gateway 的模型，该模型有一个来自 DB 的变量，名称为 $time，这是网关的创建时间来自 php time() 函数.

In my yii based sample project I have a model named gateway and this model has a variable from DB with name $time that is a creation time for gateway that comes from php time() function.

我想将此变量更改为可读形式以显示在视图中(而不是保存在数据库中)为此我编写了一个函数 setTime() 并定义了一个变量 $readabletime

I want to change this variable to a readable form to show in view (not to save in DB) and for this I wrote a function setTime() and defined a variable $readabletime

我没有在控制器中调用函数settime()，而是在模型的rules()

I didn't call function settime() in controller but in rules() of model

我写了这一行:

array('time','setTime')

但它不起作用

如何使函数在模型中工作?

How can I make a function work in model?

这是我的模型

<?php


class UserGateway extends CActiveRecord
{
public $readabletime; 
/**
 * @return string the associated database table name
 */
public function tableName()
{
    return 'user_gateway';
}


public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('name, url, ip, time, userid, gatewaycategoryid', 'required'),
        array('time, status, userid, gatewaycategoryid, defaultgateway', 'numerical', 'integerOnly'=>true),
        array('name, url', 'length', 'max'=>120),
        array('ip', 'length', 'max'=>18),
        // The following rule is used by search().
        // @todo Please remove those attributes that should not be searched.
        array('id, name, url, ip, time, status, userid, gatewaycategoryid, defaultgateway', 'safe', 'on'=>'search'),
        array('time','setTime')
    );
}

public function setTime()
{
    $this->readabletime=date('m/d/Y H:i:s', $this->time);
}

}

这是我的观点:

<?php echo CHtml::link('Advanced Search','#',array('class'=>'search-    button')); ?>

<div class="search-form" style="display:none">

</div><!-- search-form -->

<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'UserAccountnumber-grid',

'dataProvider'=>$model->search(),

'filter'=>$model,
'columns'=>array(
    'name',
     'url',
    'ip',
    'readabletime',

    array(

        'class'=>'CButtonColumn',
        'buttons'=>array(
                'update' => array(
                'url'=>'Yii::app()->createUrl(\'User/UpdateGateway\',array(\'id\'=>$data[id]))'),
                'delete' => array(
                'url'=>'Yii::app()->createUrl(\'User/DeleteGateway\',array(\'id\'=>$data[id]))'

                        ),                            ),
                )
            )             
      )        
  );
  ?>

谢谢大家的回答

推荐答案

你可以在你的模型中编写 afterFind 函数:

You could just write afterFind function in your model:

protected function afterFind()
{
    // convert to readable time format while viewing
    $this->readabletime = date('m/d/Y H:i:s', $this->time);

    parent::afterFind();
}

这样，无论在何处使用 readabletime，它都会将其转换为您想要的格式.CActiveRecord afterFind

This way wherever readabletime is used, it will convert it to your desired format. CActiveRecord afterFind
