Yii, custom widget returns null - php

Question

I want to make a custom widget like one of the examples that yii brings (blog), and the custom widget i want to make is the one called "RecentPosts", but for my page i'm going to call it "RecentTasks", so i just want to get the firsts 4 tasks on my database SQLite(almos like "recentPost" does).
in my column2:
<?php /* #var $this Controller */ ?>
<?php $this->beginContent('//layouts/main'); ?>
<div class="col-xs-12 col-sm-9">
<div id="content">
<?php echo $content; ?>
</div><!-- content -->
</div>
<div id="sidebar" class="col-xs-6 col-sm-3 sidebar-offcanvas" role="navigation">
<div class="list-group">
<?php
// $this->beginWidget('zii.widgets.CPortlet', array(
// 'title'=>'Operations',
// ));
$this->widget('zii.widgets.CMenu', array(
'items'=>$this->menu,
'htmlOptions'=>array('class'=>'nav nav-pills nav-stacked'),
));
// $this->endWidget();
?>
<?php
$this->widget('recentTasks', array(
'maxTasks'=>10
));
?>
</div>
</div>
<?php $this->endContent(); ?>
in my custom widget inside components:
<?php
Yii::import('zii.widgets.CPortlet');
class RecentTasks extends CPortlet
{
public $title = 'Recent Tasks';
public $maxTasks = 10;
public function getRecentTasks()
{
return Task::model()->findRecentTasks($this->maxTasks);
}
protected function renderContent()
{
$this->render('recentTasks');
}
}
my model:
<?php
class Task extends CActiveRecord
{
/**
* #return string the associated database table name
*/
public function tableName()
{
return 'task';
}
public function rules()
{
// NOTE: you should only define rules for those attributes that
// will receive user inputs.
return array(
array('Name, Status, Project_id, User_id', 'required'),
array('Status, Project_id, User_id', 'numerical', 'integerOnly'=>true),
array('Name, Create_time, Update_time, Assigned', 'length', 'max'=>45),
array('Description, Tags', 'safe'),
// The following rule is used by search().
// #todo Please remove those attributes that should not be searched.
array('id, Name, Description, Status, Create_time, Update_time, Tags, Project_id, User_id, Assigned', 'safe', 'on'=>'search'),
);
}
public function relations()
{
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array(
'comments' => array(self::HAS_MANY, 'Comment', 'Task_id'),
'project' => array(self::BELONGS_TO, 'Project', 'Project_id'),
'user' => array(self::BELONGS_TO, 'User', 'User_id'),
);
}
public function attributeLabels()
{
return array(
'id' => 'ID',
'Name' => 'Name',
'Description' => 'Description',
'Status' => 'Status',
'Create_time' => 'Create Time',
'Update_time' => 'Update Time',
'Tags' => 'Tags',
'Project_id' => 'Project',
'User_id' => 'User',
'Assigned' => 'Assigned',
);
}
public function findRecentTasks($limit=10)
{
$this->findAll();
}
public function search()
{
// #todo Please modify the following code to remove attributes that should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('id',$this->id);
$criteria->compare('Name',$this->Name,true);
$criteria->compare('Description',$this->Description,true);
$criteria->compare('Status',$this->Status);
$criteria->compare('Create_time',$this->Create_time,true);
$criteria->compare('Update_time',$this->Update_time,true);
$criteria->compare('Tags',$this->Tags,true);
$criteria->compare('Project_id',$this->Project_id);
$criteria->compare('User_id',$this->User_id);
$criteria->compare('Assigned',$this->Assigned,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
public static function model($className=__CLASS__)
{
return parent::model($className);
}
}
in the view of the widget im just making var_dump($this->getRecentTasks());
i haven't figure out the problem but for now its just returning NULL. I followed almost the exact same steps made on the example page in yii

Try this:
// location: /protected/components/RecentTasks.php
class RecentTasks extends CWidget
{
public $title = 'Recent Tasks';
public $maxTasks = 10;
/**
* Is called when $this->beginWidget() is called
*/
public function init()
{
}
/**
* Is called when $this->endWidget() is called
*/
public function run()
{
// render /protected/components/views/recentTasks.php
$this->render('recentTasks', array(
'models'=>$this->getRecentTasks($this->maxTasks)
));
}
public function getRecentTasks()
{
return Task::model()->findRecentTasks($this->maxTasks);
}
}
Call the widget like so in your view or layout file (with a capital):
$this->widget('RecentTasks', array(
'maxTasks'=>10
));
Then you can use $models in the view to show the tasks.
Also see: http://www.yiiframework.com/doc/guide/1.1/en/basics.view#widget
EDIT:
Seems the problem is in your findRecentTasks() method, add return before the findAll(). I also added the code to apply the limit and for conditions may you need that in the future.
public function findRecentTasks($limit=10)
{
return $this->findAll(array(
// 'condition'=>'id = :id',
// 'params' => array('id'=>$id),
'limit'=>$limit
));
}
