I’m a noob to Yii but I’ll do my best to explain the problem. Imagine a database and model design like this:
Go to the link to see the schema:
(can’t use the image extension, probably because I am new)
http://www.yiiframework.com/tutorial/image?type=guide&version=1.1&lang=en&file=has_many_through.png
In case the link doesn’t work:
Group
-----
id PK
name
Role
-----
user_id PK, FK2
group_id PK, FK1
name
User
-----
id PK
username
password
email
Comment
------
id PK
user_id FK1
content
You want to view a group so you go to the link www.website.com/group/view/1 which activates the actionView() method in GroupController. In the view there also should be a list of the users who are a member of that group so in the actionView() method of GroupController the code would look something like this:
public function actionView($id)
{
$model = $this->loadModel($id);
$users = $model->users;
$userDataProvider = new CArrayDataProvider($users);
$this->render('view',array(
'model' => $model,
'userDataProvider' => $userDataProvider,
));
}
In the Group model the relations() method would look like this:
'roles'=>array(self::HAS_MANY, 'Role', 'group_id'),
'users' => array(self::HAS_MANY, 'User', array('user_id' => 'id'), 'through' => 'roles'),
and then finally in the View the code would be like this:
<?php $this->widget('zii.widgets.CDetailView', array(
'data'=>$model,
'attributes'=>array(
'id',
'name',
)); ?>
<h1>Users</h1>
<?php $this->widget('zii.widgets.CListView', array(
'dataProvider' => $userDataProvider,
'itemView' => '/user/_view,
)); ?>
/user/_view:
<div class="view">
<b><?php echo CHtml::encode($data->getAttributeLabel('id')); ?>:</b>
<?php echo CHtml::link(CHtml::encode($data->id), array('view', 'id'=>$data->id)); ?>
<br />
<b><?php echo CHtml::encode($data->getAttributeLabel('name')); ?>:</b>
<?php echo CHtml::encode($data->name); ?>
<br />
//I want to display the users role here.....
</div>
My Question: In the list of users how would I also display their corresponding field ‘name’ from the table ‘role’?
For example: In the view I want the list of users to be displayed like this:
id name role
1 User1 owner
2 User2 member
etc......
Thanks!
