My collactions-category have 3 fields- _id ,name, parent_id
parent_id is _id of parent
In actionIndex
public function actionIndex()
{
$dataProvider=new EMongoDocumentDataProvider('Category');
$this->render('index',array(
'dataProvider'=>$dataProvider,
));
}
How I can replace parent_id by name of parent category
You don't provide enough information but I assume you wish to use this with GGridView. That is where you will have to do this, within the declaration of the CGridView:
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
array(
'name' => 'Parent',
'value' => '$data->parent->name'
)
)
);
parent in $data->parent is the name of the relation within your model to the parent model.

I have following code in my controller:
public function actionAdmin()
{
$model=new MForm('search');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['ChManageForm']))
$model->attributes=$_GET['ChManageForm'];
$this->render('admin',array(
'model'=>$model,
));
}
and
const member=1;
const district=2;
My view(called admin)
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'ch-manage-form-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
'form_name',
'region',
'phone_number',
'email',
array(
'class'=>'CButtonColumn',
),
),
)); ?>
1 and 2 appears in the column called name(in my view file) and values of this column are saved in integer format. I need to show(in my view(admin)) member and district instead of numbers(e.g member instead of 1). How can I do it?
You can also specify the grid view column like this (doesn't require a helper in your model):
array(
'name'=>'form_name',
'value'=>'$data->form_name ? \'Member\':\'District\'',
'type'=>'text',
),
this works great if you only have 2 value in the variable.

EDIT:
IF you have more than 2 values,
Model which you use to CGridView:
public function getValueText() {
return $this->getValueTextOptions[$this->form_name];
}
public function getValueTextOptions() {
return array(
1 => 'Member',
2 => 'District',
);
}
View with CGridView:
array(
'name'=>'form_name',
'value'=>'$data->getValueText()',
)
I want to fetch data from my table using CActiveDataProvider in Yii. Everything seems to be working well but when I want to display the data from another related table using relations, I get an error. 'Undefined variable $data'.
here is my admin.php view:
<h1>Manage Teams</h1>
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'team-grid',
'dataProvider'=>$dataProvider,
'columns'=>array(
'id',
'team_name',
array(
'name'=>'league_id',
'type'=>'raw',
'value'=>$data->league->league_name,
),
'create_time',
'update_time',
array(
'class'=>'CButtonColumn',
),
),
)); ?>
and here is my actionAdmin method on TeamController.php
public function actionAdmin()
{
$dataProvider=new CActiveDataProvider('Team', array(
'criteria'=>array(
'order'=>'create_time DESC',
),
'pagination'=>array(
'pageSize'=>20,
),
));
$this->render('admin',array(
'dataProvider'=>$dataProvider,
));
}
The relation is, obviously, a team belongs to a league.
You should just put the $data->league->league_name in quotes and then it will recognize the $data variable. It should look like this:
array(
'name'=>'league_id',
'type'=>'raw',
'value'=>'$data->league->league_name',
),
you need to do it like this :
your column should be
array(
'name'=>'league_id',
'value'=>array($this,'league_name'),
),
and you controller shod have a function like this:
public function league_name($data,$row)
{
return $data->league->league_name;
}
This is my category table
id category parent_category_id
1 animal NULL
2 vegetable NULL
3 mineral NULL
4 doggie 1
5 potato 2
6 hunting 4
my yii grid view shows parent category id instead of name.
how can i display the parent category name in grid view.
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'category-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
'category',
'parent_category_id',
array(
'class'=>'CButtonColumn',
),
),
)); ?>
what changes i have to make in the above code.
thanks.
First step - define relation in model class:
public function relations()
{
return array(
'parent'=>array(self::BELONGS_TO, 'Category', 'parent_category_id'),
);
}
where Category - is name of AR model class, parent_category_id - foreign key referencing to itself.
Step 2 - CGridView, columns attribute:
...
'columns'=>array(
'id',
'category',
array(
'name'=>'Parent category', // col title
'value'=>function (Category $data){
if($data->parent_category_id)
return $data->parent->category; // "parent" - relation name, defined in "relations" method
return "-= root category =-";
}
),
)
...
Note: code above requires php version>=5.3. Otherwise you have to avoid using anonymous function
'columns'=>array(
.....
array('name'=>'id','value'=>'$data->Category->name'),
)
or create function inside call getCategoryName() and retreive name
'columns'=>array(
.....
array('name'=>'id','value'=>'$data->getCategoryName()'),
)
public function getCategoryName()
{
$equery= Category::model()->find("id=$this->id");
$cnm=$equery['Category'];
return $cnm;
}
I have 2 tables/models:
Tmp1
Header
QuestionText
Tmp2
Header
Part
OutOf
I'm trying to display the columns: Header, QuestionText, Part, OutOf
in a single CGRIDVIEW.
In Tmp1 model:
public function relations()
{
return array(
'tmp2s' => array(self::HAS_MANY, 'Tmp2', 'Header'),
);
}
In Tmp2 Model:
public function relations()
{
return array(
'header' => array(self::BELONGS_TO, 'Tmp1', 'Header'),
);
}
Controller:
public function actionReviewAll()
{
$tmp1 = new Tmp1('search');
$tmp1->unsetAttributes();
if(isset($_GET['Tmp1'])){
$model->attributes=$_GET['Tmp1'];
}
$this->render('ReviewAll',array(
'tmp1'=>$tmp1,
));
}
View:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'tmp-grid',
'dataProvider'=>$tmp1->search(),
'filter'=>$tmp1,
'columns'=>array(
'Header',
'QuestionText',
array(
'name' => 'tmp2.OutOf',
'value' => '$data->tmp2[0].OutOf',
'type' => 'raw'
),
),
)); ?>
Error:
Property "Tmp1.tmp2" is not defined.
Any help is greatly appreciated
You have a sintax error:
Tmp1.tmp2 = Tmp1.tmp2s
The relation alias is with 's'. "tmp2s".
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'tmp-grid',
'dataProvider'=>$tmp1->search(),
'filter'=>$tmp1,
'columns'=>array(
'Header',
'QuestionText',
'tmp2s.Part',
'tmp2s.OutOf',
),
)); ?>
But you are trying to show a 'self::HAS_MANY' relationship, you can't show that on a normal CGridView widget...
Your code probably works (I haven't tried it), but not in cases where your tmp1 model has no tmp2's. You must make sure there is a tmp2 before accessing it:
'value' => 'isset($data->tmp2) ? $data->tmp2[0].OutOf : Null',
You can also pass a function($data,$row) to value to make it look less messy. (Yes, that's important to me.)
I am trying to set up a MANY_MANY Relationship in Yii using Active Record.
I have three tables
profile
profile_id
profile_description
category
category_id
category_name
profile_category
profile_id
category_id
My models are Profile, Category, and ProfileCategory.
I am trying to run a query using the category_id that will pull up all of the profiles that are in that category.
This is the information in the category model.
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(
'profiles'=>array(
self::MANY_MANY,
'Profile',
'profile_category(category_id, profile_id)',
),
'profile_category'=>array(
self::HAS_MANY,
'ProfileCategory',
'category_id',
),
);
}
Profile Model
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(
'categories'=>array(
self::MANY_MANY,
'Category',
'profile_category(profile_id, category_id)'
),
'profileCategory'=>array(
self::HAS_MANY,
'ProfileCategory',
'profile_id'
),
);
}
ProfileCategory Model
public function relations()
{
return array(
'category'=>array(
self::BELONGS_TO,
'Category',
'category_id',
),
'profile'=>array(
self::BELONGS_TO,
'Profile',
'profile_id',
),
);
}
Controller
public function actionResults()
{
$category=$_POST['terms'];
$dataProvider=new CActiveDataProvider(
'Profile',
array(
'criteria'=>array(
'with'=>array('profile_category'),
'condition'=>'display=10 AND profile_category.category_id=1',
'order'=>'t.id DESC',
'together'=>true,
),
)
);
$this->render('results',array(
'dataProvider'=>$dataProvider,
));
}
View
<div id=resultsleft>
<?php
foreach($dataProvider as $value)
{
echo $value->profile_id;
}
?>
</div>
Any thoughts? Thank You! Nothing shows in the view.
You have to set up a property called profileCategory (not profile_category) in the profile model:
'profileCategory'=>array(
self::HAS_MANY,
'ProfileCategory',
'profile_id'
),
You can use it with an and condition as follows:
'criteria'=>array(
'with'=>array('profileCategory'),
'condition'=>'display=10 AND profileCategory.category_id=1',
'order'=>'t.id DESC',
'together'=>true,
),
It would be better for logical id first to model relation...
An example is available here.
Category model
'Profile', 'profile_category(profile_id, ...)'
public function relations()
{
return array(
'profiles'=>array(
self::MANY_MANY,
'Profile',
'profile_category(profile_id, category_id)'
),
'profile_category'=>array(
self::HAS_MANY,
'ProfileCategory',
'category_id',
),
);
}
Profile model
'Category', 'profile_category(category_id, ...)'
public function relations()
{
return array(
'categories'=>array(
self::MANY_MANY,
'Category',
'profile_category(category_id, profile_id)'
),
'profile_category'=>array(
self::HAS_MANY,
'ProfileCategory',
'profile_id'
),
);
}
Its actualy if model of database has
many self::BELONGS_TO and database has only PK (PrimaryKeys)
such code will be correctly executed
print_r(Profile::model()->findByPk(5)->categories);
print_r(Category::model()->findByPk(8)->profiles);
