I want users to be able to have a list of other users called "contacts," similar to a friends list.
I have a table of users called user.
I have a table with two columns, user_id and contact_id, called user_contact.
I would like to join the user table on itself using the user_contact table so that every user has a list of contacts.
So far, I have set up a relation in my user model that looks like this:
return array(
'contacts'=>array(self::MANY_MANY, 'User',
'user_contact(contact_id, user_id)'),
);
In my controller I have this:
public function actionIndex()
{
$criteria = new CDbCriteria;
$criteria->condition = "t.email = :email";
$criteria->params = array(':email'=>Yii::app()->user->id);
$criteria->with = array('contacts');
$contactList=new CActiveDataProvider('User', array(
'pagination'=>array(
'pageSize'=>'5',
),
'criteria'=>$criteria,
));
$this->render('index',array(
'contactList'=>$contactList,
));
}
When I get to the view, I am dumping the contactList variable and it shows no contacts:
CActiveDataProvider#1
(
[modelClass] => 'User'
[keyAttribute] => null
[CActiveDataProvider:_criteria] => CDbCriteria#2
(
[CDbCriteria:_paramCount] => 0
[select] => '*'
[distinct] => false
[condition] => 't.email = :email'
[params] => array
(
[:email] => 'demo@demo.com'
)
[limit] => -1
[offset] => -1
[order] => ''
[group] => ''
[join] => ''
[having] => ''
[with] => array
(
[0] => 'contacts'
)
[alias] => null
)
[CDataProvider:_id] => 'User'
[CDataProvider:_data] => null
[CDataProvider:_keys] => null
[CDataProvider:_totalItemCount] => null
[CDataProvider:_sort] => null
[CDataProvider:_pagination] => CPagination#3
(
[pageVar] => 'User_page'
[route] => ''
[params] => null
[CPagination:_pageSize] => '5'
[CPagination:_itemCount] => 0
[CPagination:_currentPage] => null
[CComponent:_e] => null
[CComponent:_m] => null
)
[CComponent:_e] => null
[CComponent:_m] => null
)
