I am trying to show my data in gridview and in process have written the following query which I am trying to write using CDBCriteria,
//query
SELECT user. * , jobs. * , COUNT( jobs.user_id )
FROM user
INNER JOIN jobs ON user.id = jobs.user_id
GROUP BY user.id
I have tried the following thing:
$criteria = new CDbCriteria;
$criteria->select ='user.*,jobs.*';
$criteria->select ='COUNT(jobs.user_id)';
$criteria->select ='user';
$criteria->join ='INNER JOIN jobs ON user.id = jobs.user_id';
$criteria->group ='user.id';
return new CActiveDataProvider('manageemployers', array(
'criteria'=>$criteria,
my view have the following code.
<?php
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' =>$model->search(),
// 'filter' => $model,
'columns' => array(
array(
'name' => ' Employer ID',
'type' => 'raw',
'value' => 'CHtml::encode($data->id)',
'htmlOptions' => array('style'=>'width:90px;','class'=>'zzz'),
// 'filter'=>'false' /* for hiding filter boxes */
[...]
?>
My contoller
public function actionManageEmployers() {
$user_id = Yii::app()->session['user_id'];
if (Yii::app()->user->getId() === null)
$this->redirect(array('site/login'));
$model = new ManageEmployers();
$model->user_id = $user_id;
$this->render('manageemployers', array('model' => $model,
));
}
But its not working. Please help me on this one. Thanks!

Answer 1

If you have table relations set up, then in your User model (that refers to your user table) try writing your CDbCriteria like so:
$criteria = new CDbCriteria();
$criteria->with = array('jobs' => array('joinType' => 'STRAIGHT_JOIN'));
$criteria->together = true;
$criteria->addCondition('id = jobs.user_id');
return new CActiveDataProvider('manageemployers', array(
'criteria' => $criteria
));

EDIT
So now I'm able to understand your problem and I tried to fix it with this.
i think i had the solution, you don't need to get the data in the search() like you did it. you can use relations and other stuff to get your data.
firstly i would add a relation to your user-model like this:
'jobs' => array(self::HAS_MANY, 'Jobs', 'user_id')
after that, you can access all jobs of the user with $model->jobs
then you need to undo your changes of the search()-function. I mean that it must look like this:
public function search()
{
$criteria=new CDbCriteria;
$criteria->compare('attribute',$this->attribute);
//this is just an example ^
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
changes in the action:
$model = new ManageEmployers();
to this:
$model = new ManageEmployers("search");
changes in the view:
add something like this to your colums array:
array(
'name' => 'Total Jobs Posted',
'value' => 'count($data->jobs)',
'htmlOptions' => array('style'=>'width:90px;','class'=>'zzz'),
)
