In Goods model:
public function relations() {
return array(
'pg' => array(self::MANY_MANY, 'Project', '{{project_goods}}(pid, gid)'),


$model = Goods::model()->with('pg')->findByPk(2);
echo $model->pg.name;



Use of undefined constant name - assumed 'name'

echo $model->pg->name;

thank you.

echo $model->pg->name


Trying to get property of non-object

[Ease]

$model = Goods::model()->with("pg")->findByPk(2);
$model->dbCriteria->addCondition("pg.pid=2");
echo $model->pg->name;

> Info: If there is no related instance for a relationship, the
corresponding property could be either null or an empty array. For
`BELONGS_TO` and `HAS_ONE` relationships, the result is null; for
`HAS_MANY` and `MANY_MANY`, it is an empty array.
Note that the `HAS_MANY` and `MANY_MANY` relationships return arrays of objects,
you will need to loop through the results before trying to access any properties.
Otherwise, you may receive "Trying to get property of non-object" errors.


hope to help other people

$model->pg[0]->name

it's ok

[waterloomatt]

Yes, since it's a many-many relationship, $model->pg will return an array of Projects.

foreach ($model->pg as $project)
{
    echo $project->name;
}
