So the problem is, that I have a view that will render a CGridView containing a count value. I had to make a custom CDbCriteria so that I could select the right infos. Now I can't display it in a CGridView.
Here is my controller action that builds the CActiveDataProvider:
public function actionListProducts(){
$criteria=new CDbCriteria;
$criteria->select = 'rp_product as product, count(rp_id) as cnt';
$criteria->group = 'product';
$dataProvider=new CActiveDataProvider('report', array( 'criteria'=>$criteria,
));
$this->render('listProducts',array(
'dataProvider'=>$dataProvider,
));
}
I am trying to display it in this CGridView:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'reports-grid',
'dataProvider'=>$dataProvider,
'columns'=>array(
'product',
'cnt'
),
));
I know the data is fetched properly because my CGridView has the right number of rows... What am I suppose to write in the 'columns' description?
Thank you
If you want to use the aliases product and cnt (var AS alias), you have to make a public property of it in the model Report.
Example:
Model extends CActiveRecord {
....
public $product;
public $cnt;
...
}

In my system, I have 3 types of user, Admin, Supervisor and Normal user. Every type of user has a Supervisor who is another user itself.
Suppose we have two tables, users and documents and the relation is as follow:
Here the documents table is related with users table by user_id column.
In my system, I have a CGridview of Documents module based on the logged in user type. If the logged in user type is Admin, then it shows all the entry of the document table.
If the logged in user type is Supervisor, then it will show only those entry from documents table, where the documents.user_id is equal to those users.user_id, whose users.sp_id = LoggedInUser, sorry if I can't express it clearly.
I can show the data in CGridview by using relation in the Documents model.
public function relations(){
'users' => array(self::BELONGS_TO, 'Users', 'user_id'),
}
and in the Document model I declare two custom functions to return the desired DataProvider. Those are:
public function searchByUser($id)
{
$criteria=new CDbCriteria;
$criteria->condition = "user_id=$id";
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'sort'=>array(
'defaultOrder'=>'doc_id DESC',
),
));
}
and
public function searchBySupervisor($supervisor_id)
{
$criteria=new CDbCriteria;
$criteria->with=array('users');
$criteria->compare('user_id',$this->user_id,true);
$criteria->condition = "sp_id=$supervisor_id AND status='active'";
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'sort'=>array(
'defaultOrder'=>'doc_idDESC',
),
));
}
In my /documents/adminview, I use the dataProvider based on the loggedin user in the CGridview:
if ($UserType=="Normal_User"){
$this->widget(
'booster.widgets.TbGridView', array(
'type' => 'striped bordered condensed',
'dataProvider'=>$model->searchByUser(Yii::app()->user->getId()),
elseif($UserType == "supervisor"){
$this->widget(
'booster.widgets.TbGridView', array(
'type' => 'striped bordered condensed',
'dataProvider'=>$model->searchBySupervisor(Yii::app()->user->getId()),
Everything is working fine except my search function isn't working. If I logged in as the supervisor, means if I use this: 'dataProvider'=>$model->searchBySupervisor(Yii::app()->user->getId()), dataprovider, my advance search option doesn't filter the gridview based on the searching parameter, its returning same data.
I use a search symptoms form and I pass off the symptomCode to my diseaseController
both symptoms and diseases have model classes, but the table connecting the 2 does not.
I use this query to find all the diseases that have the specific symptom
$diseaseCodes = Yii::app()->db->createCommand()
->select ('ICD10')
->from('tbl_disease')
->join('tbl_symptom_disease', 'tbl_disease.ICD10=tbl_symptom_disease.diseaseCode')
->where('symptomCode=:symptomCode',
array(':symptomCode'=>$_GET['symptomCode']))
->queryAll();
Now I want to know how I can use this to populate a dataprovider to populate a gridview
One idea I had was to create a custom model function
public function queryResultSearch($diseaseArray)
{
$criteria=new CDbCriteria;
$criteria->compare('ICD10',$diseaseArray,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
And use this to render yii's admin action (for disease models), but I can't get it to work because probably my entire way at going at this is wrong.
Can someone help me please? How to use a mysql query result to populate an activedataprovider object.
Thank you for your time
In your controller action you can try this:
$model=new ModelName('search');
$model->unsetAttributes();
if(isset($_GET['ModelName']))
$model->attributes=$_GET['ModelName'];
$diseaseCodes = Yii::app()->db->createCommand()
->select ('ICD10')
->from('tbl_disease')
->join('tbl_symptom_disease', 'tbl_disease.ICD10=tbl_symptom_disease.diseaseCode')
->where('symptomCode=:symptomCode',
array(':symptomCode'=>$_GET['symptomCode']))
->queryAll();
$diseaseArray=array();
foreach ($diseaseCodes as $dc) {
$diseaseArray[]=$dc['ICD10'];
}
$criteria=new CDbCriteria;
$criteria->compare('ICD10',$diseaseArray,true);
$dataProvider = new CActiveDataProvider(get_class($model),array('criteria'=>$criteria));
$dataProvider->criteria->mergeWith($model->search()->criteria);
$this->render('view',array(
'model'=>$this->loadModel($id),
'dataProvider'=> $dataProvider,
));
You are going to want to use CArrayDataProvider. This is less than ideal.. and you will have to implement all your sorting and pagination on your own
You are much better off using a model and implementing similar to
public function queryResultSearch($diseaseArray)
{
$criteria=new CDbCriteria;
$criteria->compare('ICD10',$diseaseArray,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
To make your first model I would personally use Gii.
I have two tables , one album and one photo. the photo table has a FK (album_id) which refer to id in album table.
now I want to show photos in CListview but I don't know how. :(
As I see it is uses dataProvider and I don't know how to combine relation with it.
would you help me?
Thank you masters.
It's simple
$dataProvider=new CActiveDataProvider('Photo', array(
'criteria'=>array(
'condition'=>'album_id=:album_id',
'params'=>['album_id'=>$album_id]
)
));
Then in view use this dataProvider:
$this->widget('zii.widgets.CListView', array(
'dataProvider'=>$dataProvider,
'itemView'=>'_photo'
));
First you should create the relation in you models.
In Album.php add sth like this:
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(
'photos'=>array(self::HAS_MANY, 'Photo',array('album_id'=>'id')),
);
}
Similar in Photo.php:
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(
'album'=>array(self::BELONGS_TO, 'Album',array('id'=>'album_id')),
);
}
Now you can use it in your code:
$dataProvider=new CActiveDataProvider('Photo', array(
'criteria'=>array(
'condition'=>'album_id='.$yourAlbumId,
)
));
$this->widget('zii.widgets.CListView', array(
'dataProvider'=>$dataProvider,
...
));
If you need to refer to the Album in the CListview (let's say you have a field called "title" in the Album model), you can refer to it as $data->album->title in your items template.
I have 2 models: taxiDrivers and taxiOrders. In taxiOrders I have a field driver_id, but instead of just an id, I want to output driver's name (which is located in taxiDrivers). Both models are generated via gii, and crud tools are also generated. The page which is needed to be changed is taxiOrders/admin (view: admin.php, models: TaxiOrders.php, TaxiDrivers.php and respective controllers)
2 DCoder: Thanks dude! but one more query I have and hope you can clearify: I have a standart generated admin.php view page with following code:
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'taxi-orders-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
'uid',
'did',
'type',
'notes',
//'or_lat',
//'or_lng',
//'des_lat',
//'des_lng',
'cost',
'rating',
'date',
'time',
'status',
array(
'class'=>'CButtonColumn',
),
),
)); ?>
and below code is for controller:public function actionAdmin()
{
$model=new TaxiOrders('search');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['TaxiOrders']))
$model->attributes=$_GET['TaxiOrders'];
$this->render('admin',array(
'model'=>$model,
));
}
So can u please show me where I could put your manipulations.
The Yii way would be to define a Relation between the two model classes (and enforce it with a Foreign Key). Then Yii would know how the two classes are related and you would have an easier time loading the related data.
In the TaxiOrders model class, a relation would look like this:
/**
* #property TaxiDrivers $Driver
*/
class TaxiOrders extends CActiveRecord {
// ...
public function relations() {
return array(
'Driver' => array(self::BELONGS_TO, 'TaxiDrivers', 'driver_id'),
);
}
// ...
}
In the controller, when you load the order data, you can prefetch the associated driver data like this:
public function actionOrderInfo($orderID) {
$order = TaxiOrders::model()->with('Driver')->findByPk($orderID);
// render it
}
with('Driver') will make sure that each returned order has its driver info already loaded, no matter if you need to find one record or a lot of records. It is a lot more efficient than trying to load that related data yourself.
In the view, you can output the driver info like this:
echo CHtml::encode($order->Driver->Name);
Unless you have a foreign key to ensure data integrity, it is possible that the Driver has been deleted without clearing his existing orders... In that case $order->Driver will be NULL and the line above will cause an error. Figuring out how to avoid it should be obvious.
In TaxiOrders admin use this to display driver name
TaxiDrivers::getName($data->driver_id);
Now in the TaxiDrivers Model write a function with sql query to get the driver name like this...
public function getName($getid) {
$sql = "SELECT name from `taxi_drivers` where `driver_id`='$getid'";
$command=yii::app()->db->createCommand($sql);
$rs = $command->queryScalar();
return $rs;
}
I Hope it will help you..
I always prefer Query Builder approach instead of Active record approach in joined scenarios. Like that
First Get Data through Query Builder
public function getTaxtOrder($id) {
$select = Yii::app()->db->createCommand()
->select('to.*, td.name as driver_name')
->from('TaxiOrders to')
->join('TaxiDriver td', 'td.id = to.driver_id')
->where('to.id = :id', array(':id' => $id));
return $select->queryRow();
}
Then Pass through controller
$data = TaxiOrders::model()->getTaxtOrder($id);
$this->render('view',array(
'data' => $data
));
Last use this into views
$this->widget('zii.widgets.CDetailView', array(
'data'=>$data,
'attributes'=>array(
array('label' => 'Order No', 'value' =>$model['order_no']),
array('label' => 'Driver Name', 'value' =>$model['driver_name']),
array('label' => 'Date', 'value' =>$model['order_date']),
),
));
This approach easily and flexibly work with multiple joined tables than Active Record Approach.
Please consider this:
class User extends CActiveRecord
{
...
public function relations()
{
return array(
...
'articleCount' => array(self::STAT, 'Article', 'userid'),
...
);
}
...
}
Now, I need to create a $dataProvider = new CActiveDataProvider(...) to feed a CListView widget to which I want add articleCount to the property sortableAttributes so that I can sort User records according to the number of articles the user is the author for.
What are the most convenient method? what are the other alternatives?
Well, it took me a while, but I finally got it figured out. ;)
First, make sure you still have the same STAT relation you mention in your question.
Then, in your search() method where you are building your CDbCriteria for the CActiveDataProvider, do something like this:
public function search() {
$criteria=new CDbCriteria;
$criteria->select = 't.*, IFNULL( count(article.id), 0) as articleCount';
$criteria->join = 'LEFT JOIN article ON article.userid = t.id';
$criteria->group = 't.id';
// other $criteria->compare conditions
$sort = new CSort();
$sort->attributes = array(
'articleCount'=>array(
'asc'=>'articleCountASC',
'desc'=>'articleCountDESC',
),
'*', // add all of the other columns as sortable
);
return new CActiveDataProvider(get_class($this), array(
'criteria'=>$criteria,
'sort'=>$sort,
'pagination'=> array(
'pageSize'=>20,
),
));
}
Then, in your View where you output your CGridView, do this like so:
<?php $this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$model->search(),
'columns'=>array(
'articleCount',
// other columns here
)
)); ?>
This works, I tested it (although I did not use the exact same names, like 'article', but the basic idea should work :) I did add some bonus features so it works better (like the IFNULL magic) but most of the credit goes to this Yii forum post:
http://www.yiiframework.com/forum/index.php?/topic/7061-csort-and-selfstat-to-sort-by-count/
I hope this helps! They should add better support for this though, so you don't need to make these tricky SELECT statements. Seems like something that should 'just work', I would file an 'enhancement' request in the Yii bug tracker.
