i want to search multiple models in Yii application. The search result are displayed in CList view. Need to use dataprovider in list view. So how can i use multiple dataprovider in Clist view?
You cannot make use of multiple dataproviders rather you combine the result in a single dataprovider
Something like this to get you started:
public function actionSearch($q) {
// Sanitize input
$q = strtolower(strip_tags($q));
$q = preg_replace('/[^a-z 0-9 _ \- \']/', '', $q);
$model1 = Model1::model()->findAll('title LIKE "%'.$q.'%"');
$model2 = Model2::model()->findAll('title LIKE "%'.$q.'%"');
$rawData = array_merge($model1, $model2);
$dataProvider = new CArrayDataProvider($rawData, array(
'sort'=>array(
'attributes'=>array(
'datePublished DESC', 'title',
),
),
'pagination'=>array(
'pageSize'=>10,
),
));
$this->render('search', array(
'dataProvider' => $dataProvider,
'query' => $q,
));
}

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)
));
}
?>
I know we can show a gridview with a model and it's search method and filter the results, but can we make a gridview with another dataprovider and another model like this and filter its results? Does filter needs to be a part of dataprovider?
$attr = Yii::app()->request->getParam($name);
$model = new User('search');
$model->unsetAttributes();
$model->setAttributes($attr);
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $myDataProvider,
'filter' => $model,
'columns' => array(
array(
'name' => 'username',
'type' => 'raw',
'value' => 'CHtml::encode($data->username)'
),
array(
'name' => 'email',
'type' => 'raw',
),
),
));
The above code doesn't work and I need to add a filter on a previously made data provider.
Btw $attr has a valid data, but grid is not filtered.
$model doesn't affect $myDataProvider since the data provider is not obtained using this model.
$model->search() returns a CActiveDataProvider which contains a CDbCriteria instance. Different CDbCriteria can be combined using mergeWith(). So if you would like the data to be filtered using the values from the $model
...
$model->setAttributes($attr);
$newDataProvider=$model->search();
$myDataProvider->criteria->mergeWith($newDataProvider->criteria);
$this->widget('zii.widgets.grid.CGridView', array(
...
Filter does not need to be a part of dataprovider, but data provider needs to take the model into account, if you want to use it for filtering.
The way this is done by default is to create the data provider using search method on your model, which sets conditions of your data provider based on model values, like so:
'dataProvider' => $model->search()
There is nothing preventing you from creating different data provider, for example:
'dataProvider' => $model->createAnotherDataProvider()
And in your User model:
public function createAnotherDataProvider() {
{
// create your second data provider here
// with filtering based on model's attributes, e.g.:
$criteria = new CDbCriteria;
$criteria->compare('someAttribute', $this->someAttribute);
return new CActiveDataProvider('User', array(
'criteria' => $criteria,
));
}
I am trying to implement sorting with Yii list view. I have joined 2 tables named provider_favourite and service_request in list view. And the fields and contents from both tables are listing in the list view. But sorting is working only in provider_favourite table, not from service_request table.How can I sort the fields from service_request table? Iam using csort for sorting. I also tried CGrid view. But the same problem is happening in grid view also ..
Iam using the following code to join
$criteria = new CDbCriteria;
$criteria->select = 'favourite_notes,favourite, favourite_added_date,max_budget,preferred_location,service_name';
$criteria->join = 'LEFT JOIN service_request AS s ON service_request_id = favourite';
$criteria->condition = 'favourite_type = 1';
$sort=new CSort('ProviderFavourite');
// $sort->defaultOrder='s.max_budget ';
$sort->applyOrder($criteria);
$sort->attributes = array(
'max_budget' => 'service_request.max_budget',
'service_name' => 'service_request.service_name',
'favourite_added_date'
);
$type = 2;
$data = new CActiveDataProvider('ProviderFavourite', array('criteria' => $criteria, 'pagination' => array('pageSize' => 4),'sort'=>$sort
));
$this->renderPartial('favourites', array(
'ModelInstance' => ProviderFavourite::model()->findAll($criteria),
'dataProvider' => $data, 'type' => $type, 'sort'=>$sort,
));
and also Iam providing sortable attributes in list view
$this->widget('zii.widgets.CListView', array('dataProvider'=>$dataProvider,'itemView'=>'index_1',
'id'=>'request',
'template' => ' {items}{pager}',
'sortableAttributes'=>array('favourite_notes','max_budget','service_name')
));
If more details needed, I will provide. Thanks in advance
You have to specify attributes property of your $sort instance. By default only fields of $modelClass (ProviderFavourite in your case) are sortable.
I think it could look like this (not tested):
$sort->attributes = array(
'service_name' => array(
'asc' => 's.service_name ASC',
'desc' => 's.service_name DESC'
),
// ...another sortable virtual attributes from service_request table
"*"
);
You should not create a CSort object in $sort. The CActiveDataProvider will already provide you with the right sort object. The way you do it, you apply the sort criteria to $criteria before you configure the sort attributes. That can not work.
You should try a simple setup like this instead:
$data = new CActiveDataProvider('ProviderFavourite', array(
'criteria' => $criteria,
'pagination' => array('pageSize' => 4),
'sort'=> array(
'attributes' => array(
'service_name' => array(
'asc' => 's.service_name ASC',
'desc' => 's.service_name DESC'
),
// ...
),
));
If you need to access the related CSort object (which you usually don't if you use a CGridView or CListView, because they deal with that for you), then you get it via $data->sort.
Im using CArrayDataProvider for pagination. Now only page numbers are passed in url. I want to pass some more additional attributes. How do I do that? Here is my dataprovider.
$dataProvider = new CArrayDataProvider($arrayData, array(
'keyField'=>'entity_id',
'sort'=>array(
'attributes'=>array('entity_id'),
'defaultOrder'=>array('entity_id' => false),
),
'pagination'=>array(
'pageSize'=>20,
),
));
CPagination takes params. Try adding 'params' => array('foo' => 'bar') in pagination.
The question was how to pass "additional" parameters.
The code of the accepted answer will override your existing $_GET parameters:
'params' => array('foo' => 'bar')
To add "additional" parameters, first add them to existing $_GET parameters:
$pagerparams = $_GET;
$pagerparams['foo'] = 'bar';
$dataProvider = new CActiveDataProvider($this, array(
'pagination'=>array(
'params' => $pagerparams,
),
...
));
lets say i have a table named
cars{
'id','name','brand_id',
}
and another table
brand{
'id','brand_name',
}
I have a situation that i want to generate an Excel report with the following attributes.
'name','brand_name' i.e. SELECT cars.name, brand.brand_name FROM cars INNER JOIN on brand WHERE cars.brand_id = brand.id
So i created a dataprovider like this:
$sql = "SELECT cars.name, brand.brand_name FROM cars INNER JOIN brand on cars.brand_id = brand.id";
$result = Yii::app()->db->createCommand($sql)->queryAll();
$this->render('doc', array('dataprovider' => $result));
Now i want to generate Excel file with result as a dataProvider so i write the following code:
// lets say i am doing this in view page named doc.php
$factory = new CWidgetFactory();
Yii::import('ext.eexcelview.EExcelView',true);
$widget = $factory->createWidget($this,'EExcelView', array(
'dataProvider'=>$dataprovider->search(),
'grid_mode'=>'export',
'title'=>'Title',
'creator'=>'TNC',
'autoWidth'=>false,
'filename'=>'Report.xlsx',
'stream'=>false,
'disablePaging'=>false,
'exportType'=>'Excel2007',
'columns'=>array(
'name',
'brand_name',),
'showTableOnEmpty' => false,
));
$widget->init();
$widget->run();
I have included all the extensions that i have to.. This code is working when i fed the dataProvider field with a single table entry .
But the situation arises when i include multiple tables.
These lines don't actually make a dataprovider:
$result = Yii::app()->db->createCommand($sql)->queryAll();
$this->render('doc', array('dataprovider' => $result));
You'll want to do something like the following:
$dataprovider = new CSqlDataProvider($sql, array(
'pagination'=>false,
);
$this->render('doc', array('dataprovider' => $dataprover);
More info here: http://www.yiiframework.com/doc/api/1.1/CSqlDataProvider
This works for 2 tables, dont know works for more than 2 or not.
$dataProvider = new CArrayDataProvider($dataprovider, array('id' => 'brand', 'sort' => array('attributes' => array('brand_name', ), ), 'pagination' => false));
$this -> render('doc', array('dataprovider' => $dataProvider,));
