Why my dataprovider is not displaying pagination?
$dataProvider=new CSqlDataProvider($sql,array('keyField' =>'inmueble_id','pagination'=>array('pageSize'=>1)));
I dont see the problem T_T
You need to pass the totalItemCount property with a count of the data you are fetching from query.
Ex:
$count=Yii::app()->db->createCommand('SELECT COUNT(*) FROM YOUr_TABLE')->queryScalar();
and pass count as
$dataProvider=new CSqlDataProvider(
$sql,
array(
'totalItemCount'=>$count,
'keyField' =>'inmueble_id',
'pagination'=>array('pageSize'=>1)
)
);

I need to conver this sql statement that has a multi column group by clause into CActiveDataProvider in Yii version 1.1.4?
select * from my_table_name group by bookname,categorytitle,bookkey order by bookname,categorytitle,bookkey asc;
I need a CActiveDataProvider to feed a CGridView search function. Apparently, I only have a simple return in my model of the search function that runs my CGridView
return new CActiveDataProvider(get_class($this),
array(
'criteria' => $criteria,
'sort' => array(
'defaultOrder' => 'id ASC'
),
'pagination' => array('pageSize' => ActiveRecord::PAGE_SIZE),
));
so how to convert the sql statement that I gave into CActiveDataProvider format ?
You can do using two way -
Make sql view and than create yii model and use this in your
controller or page view.
Create custom search function in your existing model and use group by
e.g. -
<?php
public function new_search(){
$criteria = new CDbCriteria();
...
..
$criteria->group = "bookname, categorytitle, bookkey";
$criteria->order = "bookname, categorytitle, bookkey";
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination'=>array('pageSize'=>100)
));
}
?>
In my Yii web application, having student table for saving student details. I want to student name in alphabetical order when retrieve data from student table.
public function defaultScope() {
return array("order" => "student_firstname");
}
I tried this function, but not working properly.
Please help me.
Thanks in advance.
you can use the defaultOrder property of CSort. For example...
$dataProvider=new CActiveDataProvider('Example', array(
'sort'=>array(
'defaultOrder'=>array(
'student_firstname'=>false
)
)
));
In model's search method for data provider try to set default order, like this:
$dataProvider=new CActiveDataProvider($this, array(
'sort'=>array(
'defaultOrder'=> 'student_firstname ASC'
)
));
In model's search method for data provider try to set default order, like this:
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination'=>array(
'pageSize'=>Yii::app()->params['defaultPageSize'],
),
'sort'=>array(
'defaultOrder'=>array(
'student_firstname'=>CSort::SORT_ASC
),
),
));
I am a newbei in yii, when a person clicks on a category display him all products under that particular category in a gridview

'select'=>'name,model,price,brand',
'condition'=>'category=:category',
'params'=>array(':category'=>$id),
)));
var_dump($dataProvider);
return $dataProvider;
}
CException
Property "CActiveDataProvider.sellerSelectedCategoryProducts" is not defined.
PLEASE HELP! I am losing my mind on this ... not able to display in gridview.
Pass $id to your view file.
$this->render('productcategory',array('model'=>$model,'id'=>$id));
Then pass id to model function in ccgridview function.
'dataProvider'=>$model->SelectedCategoryProducts($id),
Hope this might help
Controller file
public function actionProductcategory($id)
{
$model=new Product;
$this->render('productcategory',array('model'=>$model,
'id'=>$id));
}
In View file
'dataProvider'=>$model->SelectedCategoryProducts($id),
UPDATE 1
'columns'=>array(
'name',
'model',
'brand',
'price',
change them to lowercase which are your original column names
$dataProvider=new CActiveDataProvider('Product', array(
'criteria'=>array(
'select'=>'name,model,price,brand',
'condition'=>'category=:category',
'params'=>array(':category'=>$id),
)));
this can retrieve needed data.... first check that data is perfect ... is it right after that take second step....
i am newbii in yii development and have an issue while displaying data using cgridview as it is showing only first record
Motel,Hotel,Roomcategory and halls are models in which PK and FK are passing ...
Code is here
$sponsorm = Motel::model()->find('MotelId=:MotelId', array(':MotelId'=>Yii::app()->user->id));
$sponsorhotel = Hotel::model()->find('hotelId=:hotelId', array(':hotelId'=>$sponsorm->MotelId));
$room = Roomcategory::model()->find('hotelId=:hotelId', array(':hotelId'=>$sponsorhotel->hotelId));
$halls = Halls::model()->find('hotelId=:hotelId', array(':hotelId'=>$sponsorhotel->hotelId));
echo CHtml::image(Yii::app()->request->baseUrl.'/img/4.png');
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'businessowner-grid',
'dataProvider'=>$room->search(),
//'filter'=>$sponsore,
'columns'=>array(
'roomCategoryNames',
'noOfRooms',
'price',
),
));
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'businessowner-grid',
'dataProvider'=>$halls->search(),
//'filter'=>$sponsore,
'columns'=>array(
'Type',
//'noOfHalls',
'seats',
'price',
),
));
Right now you are finding only one record because you use find to get one specific record. So you assign this record data to model variables and then you do
$model->search();
This searches from specific table multiple values but you have set the attributes so, that it matches only one record.
To get Motel gridview data use following code:
$sponsorm = $dataProvider=new CActiveDataProvider('Motel', array(
'criteria'=>array(
'condition'=>'MotelId = :MotelId',
'params' => array(':MotelId'=>Yii::app()->user->id)
),
));
It is doing the same as search() but the difference is that searching criteria is different. You can use also code below.
$motelModel = new Model();
$motelModel->MotelId = Yii::app()->user->id;
Now there is only one attribute assigned an is setting a criteria to match all rows what has this user id in MotelId field.
$modelModel->search();
Also, I see that you echo something between logic. Please do not do that. Output data only in views and keep the logic out of views. :)
I have two tables: user and asset and there is user_asset table that makes many_many relation
Now I want to show only the assets related with logged-in user in CGridView (user_id comes from Yii::app()->user->id)
How to write a criteria that makes it possible?
1) You need to define your relations in both of the model
user:
'assets' => array(self::MANY_MANY, 'Asset', 'user_asset(user_id, asset_id)'),
asset:
'users' => array(self::MANY_MANY, 'Asset', 'user_asset(asset_id, user_id)'),
2) You Create a dataProvider that will fetch only the recquired datas (define it in a model (best) or a controller bu not in a view):
$dataProvider=new CActiveDataProvider('Asset', array(
'criteria'=>array(
'with'=>array(
'users'=>array(
'condition' => 'id = ' . Yii::app()->user->id
),
),
),
...
));
3) You give to your CGridView the good provider:
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
...
));
The code is given as example, you should adapt it to your need!
I got it work, adding this inside the Model class's search method:
$criteria->with=array(
'users'
);
$criteria->together = true;
$criteria->condition = "users_users.user_id='".Yii::app()->user->id."'";
... and inside CActiveDataProvider declaration:
'criteria'=>array(
'with' => 'users',
'together'=>true,
'condition'=>'users_users.user_id = '.Yii::app()->user->id,
),
Maybe not the best way but does what needed. users_users is sql table alias by Yii, I got a hint from error message :)
