Accessing value of indirectly related models - php

I am displaying a CGridView below CDetailView on view.php page for Company model. I have problem in displaying values in CGridView using company details. The company model has an array of CompanyAddresses which is used as CArrayDataProvider for CGridView.
$config = array();
$dataProvider = new CArrayDataProvider($rawData=$model->companyAddresses,$config);
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider
, 'columns'=>array(
//'id',
array('header'=>'SN.',
//'value'=>'++$row', // may nt work with pagination but the below does work
'value'=>'$this->grid->dataProvider->pagination->currentPage * $this->grid->dataProvider->pagination->pageSize + ($row+1)',
),
'address',
array(
'name'=>'Tehsil',
//'value'=> Utility::getTehsilName(Tehsil::model()->findByPk('tehsil_id')),
'value'=> Utility::getTehsilName($this->loadModel('tehsil_id')),
//'value'=> Tehsil::model()->findByAttributes( array('id' => 'tehsil_id' ) )->name,
),
array(
'name'=>'address_tag_id',
'value'=>AddressTag::model()->findByPk('address_tag_id'),
),
)
));
I am not able to fetch Tehsil_Name from Tehsil Table which has its ID inside CompanyAddress table.

Your using value attribute is wrong, check this:
'value'=>function($data){
return Utility::getTehsilName($data->tehsil_id);
},

value is a php expression that is evaluated to produce the contents of the gridview cell as below
'value' => 'Utility::getTehsilName($this->grid->controller->loadModel($data->tehsil_id))'
If you had used relation chaining to solve this your expression would have been simplified to say:
'value' => '$data->model1->tehsil->name'
where model1 is the middle relation.

yii filter in two cgrdiview with same model

I have two cgridview that using same model.
When I use filters, the textfield names are the same (model class).
It's possible modify this name?
example:
$model1 = new ClassName;
$model2 = new ClassName;
if(isset($_GET['cgrdiview_1'])) {
$model1->attributes = $_GET['cgrdiview_1'];
}
if(isset($_GET['cgrdiview_2'])) {
$model2->attributes = $_GET['cgrdiview_2'];
}
Instead I have:
$_GET['model_class']
for both cgridview
Yes, It is possible by adding an id field.
The id attribute specifies a unique id for an HTML element (the value must be unique within the HTML document).
The id attribute is most used to point to a style in a style sheet, and by JavaScript (via the HTML DOM) to manipulate the element with the specific id.
If you check the Yii API Documentation for CGridView You can see that you can set an id field for the CGridview.
In your view, change the CGridview code to contain the following:
'id' => 'cgridview_1'
This code needs to be added at the top of your gridview. For example:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'cgridview_1',
'dataProvider'=>$dataProvider,
'columns'=>array(
'title', // display the 'title' attribute
'category.name', // display the 'name' attribute of the 'category' relation
'content:html', // display the 'content' attribute as purified HTML
array( // display 'create_time' using an expression
'name'=>'create_time',
'value'=>'date("M j, Y", $data->create_time)',
),
array( // display 'author.username' using an expression
'name'=>'authorName',
'value'=>'$data->author->username',
),
array( // display a column with "view", "update" and "delete" buttons
'class'=>'CButtonColumn',
),
),
));
I solved my problem with custom filter in each column:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'cgridview_2',
'dataProvider' => $data,
'filter' => $filter,
'columns'=>array(
array(
'name' => 'column1',
'filter' => CHtml::textField("cgridview2[column1]", $filter->column1),
),
array(
'name' => 'column2',
'filter' => CHtml::textField("cgridview2[column2]", $object->column2),
),

three table based relation display in yii gridview

I'm getting foreign key relation based display ids in the gridviews. How to get values instead of ids? Code in my gridview is following:
$criteria->compare('education.UniversityNameid',$this->UniversityName, true);
my gridviews inside code
array(
'name' => 'UniversityName',
'type' => 'raw',
'value'=>'(empty($data->education->UniversityNameid))? "" : Yii::app()->params["currencySymbol"]." ".$data->education->UniversityNameid',
),
You have to set up a relation in your model "University" 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(
'UniversityName' => array(self::BELONGS_TO, 'University', 'UniversityNameid'),
);
}
thank you can access the Name
$data->education->UniversityName
Set the relation in your model like
'u' => array(self::BELONGS_TO, 'University', 'UniversityNameid'),
and acess it like
'attributes'=>array(
array('name'=>'u.UniversityName',
'label'=>'University',),
),

Data isn't displaying from another table in CGridView Widget

I have two table Event and EventCategory. I am using zii.widgets.grid.CGridView widget to display all the events in the admin section.
I have created the following relations between tables.
Relation in EventCategory model:
'event' => array(self::HAS_MANY, 'Event', 'category_id'),
Relation in Event model:
'category' => array(self::BELONGS_TO, 'EventCategory', 'category_id'),
The following code I am using to display the Events:
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'event-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'summaryText'=> '',
'columns'=>array(
array('header'=>'Id','name'=>'event_id','filter'=>''),
'event_code',
'category.evntcatm_name',
'event_name',
array(
'class'=>'CButtonColumn',
'htmlOptions'=>array('class'=>'actions aligncenter'),
'deleteButtonImageUrl'=>false,
'updateButtonImageUrl'=>false,
'viewButtonImageUrl'=>false
),
),
)); ?>
'category.evntcatm_name' doesn't display anything. It is just creating the blank column with NO ERROR. What I am missing here.
Please try something like it
$data->category->evntcatm_name
You should use code like this:
'columns' = array(
/*YOUR DATA*/
array(
'name' => 'category_id',
'value' => function($data) {
return !empty($data->category) ? $data->category->evntcatm_name : null;
}),
)
This way can solve your problem with "Trying to get property of non-object". If you see blank cell in grid that means you miss relation (or it doesnt exist, in this way you should check relation condition or database)
Here is a few wild guesses:
Is category.evntcatm_name correctly spelled?
Is there actually data in the evntcatm_name field to begin with?
I know it might sound too simple to miss, but the error almost has to be on that level.
Try finding a category using the primary key and output it's evntcatm_name.
$cat = EventCategory::model()->findByPk(1);
echo $cat->evntcatm_name;
Maybe if you could share your schema for those two tables?
You can use
array(
'header' => 'Category Title',
'value' => '$data->category->evntcatm_name'
),
instead of 'category.evntcatm_name'
The model instance is not object now in the Cgidview:
Try
$data['category']['evntcatm_name'];

cgridview related fields filtering

I have a problem that I have solved for all but one of the cgridview filters, which is a related field.
I am using a solution Seenivasan has supplied but the related field status does not get added to the string.
here is the cgridview :-
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'tbl-orders-grid',
'dataProvider'=>$dataProvider,
'afterAjaxUpdate'=>"function() {
jQuery('#Orders_date_first').datepicker(jQuery.extend({showMonthAfterYear:false}, jQuery.datepicker.regional['id'], {'showAnim':'fold','dateFormat':'yy-mm-dd','changeMonth':'true','changeYear':'true','constrainInput':'false'}));
jQuery('#Orders_date_last').datepicker(jQuery.extend({showMonthAfterYear:false}, jQuery.datepicker.regional['id'], {'showAnim':'fold','dateFormat':'yy-mm-dd','changeMonth':'true','changeYear':'true','constrainInput':'false'}));
}",
'filter'=>$model,
'columns'=>array(
array(
'name'=>'id',
'type'=>'raw',
'value'=>'str_pad($data->id,8-strlen($data->id),"0",STR_PAD_LEFT)',
'htmlOptions'=>array('style' => 'text-align: right;width: 60px;')
),
array(
'name'=>'date_order_placed',
'filter'=>$dateisOn,
'value'=>'date("d-m-Y",strtotime($data->date_order_placed))',
),
array(
'name'=>'status',
'type'=>'raw',
//'htmlOptions'=>array('id' => 'order_status_search'),
'value'=>'CHtml::value($data,"status.orders_status_name")',
'filter'=>CHtml::listData(OrderStatus::model()->findAll(
array(
'select'=>array('orders_status_name'),
'distinct'=>true
)),"orders_status_name","orders_status_name")//this is the focus of your code
),
array(
'class'=>'EButtonColumnWithClearFilters',
'clearVisible'=>true,
'template'=>'{view}{email}',
'buttons'=>array
(
'email' => array
(
'label'=>'Reprint invoice and email to yourself',
'imageUrl'=>Yii::app()->request->baseUrl.'/images/email.png',
'url'=>'Yii::app()->createUrl("orders/ureprint", array("id"=>$data->id))',
),
),
),
),
)); ?>
here is the php and js that adds the current filter values to the url.
echo CHtml::button('List Orders',array('id'=>'listelement'));
Yii::app()->clientScript->registerSCript('test','
$("body").on("click","#listelement",function(){
var str="&";
$.each($("#tbl-orders-grid input").serializeArray(),function(i,j){
str=str+j.name+"="+j.value+"&";
});
window.location="'.CHtml::normalizeUrl(array('orders/index')).'"+str;
});
');
The other filters, dates and id, work perfectly. They are added to the url above. Status is not.
1- you need to define new filters in your model serach() methode for example like
$criteria->compare('Restaurant.Name',$this->Name,true);
Restaurant is your relation key , name : value from another table related to this fk
2- you have to add value of gridview column like :
view:
array(
'name' => 'Restaurant.Name',
'header' => 'Username',
'filter' => CHtml::activeTextField($model, 'name'),
'value' => '$data->Restaurant->Name',

yii CGridView filter with relations

How to convert model data objects array to dataProvider

Suppose I have model User which have many to many relation to itself named as friends.
so $user->friends (or $model->friends in view) gives me an array of User objects. I wanted to display the friends as gridview. But CGridView data as dataProvider object. Googling for it found the way to convert array of model objects to dataProvider object as given below.
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'gridUser',
'dataProvider' => new CArrayDataProvider($model->friends, array()),
));
Now using this I get an error
Property "User.id" is not defined.
UPDATE
public function relations()
{
return array(
'friends' => array(self::MANY_MANY, 'User', 'friendship(user_id, friend_id)'),
);
}
I use two stage building the provider shown below. But I found that it gives you trouble in terms of Pagination. I have not bothered to resolve that problem since am doing other things
$dataProvider = new CArrayDataProvider('User');
$dataProvider->setData($model->friends);
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'gridUser',
'dataProvider' =>$dataProvider,
));
That being said, your code should work (see the example below from API docs). I suspect there is wrong attribute in your relations than the provided code. Re-check the relation definition if it is ok
From Yii docs:
$rawData=Yii::app()->db->createCommand('SELECT * FROM tbl_user')->queryAll();
// or using: $rawData=User::model()->findAll(); <--this better represents your question
$dataProvider=new CArrayDataProvider($rawData, array(
'id'=>'user',
'sort'=>array(
'attributes'=>array(
'id', 'username', 'email',
),
),
'pagination'=>array(
'pageSize'=>10,
),
));
Got it :) , i can use CActiveDataProvider instead of CArrayDataProvider as given below
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'gridUser',
'dataProvider' => new CActiveDataProvider('User', array(
'data'=>$model->friends,
)),
//...... columns display list.....
));
Anyways thanks for the reply #Stefano
