How to check if authenticated user is handler of REST resourece - rest

Question

I've developing a REST service on Yii2 and Angular 2 client. Using Bearer JWT authentication.
For example there is a uri: http://127.0.0.1/v1/accounts/123456/meters, which should return all user's meters by account, which he own.
Applied router rule:
'<accountId:\w+>/<action:[\w-]+>' => '<action>',
Controllers has following behaviors:
'authenticator' => [
'class' => HttpBearerAuth::className(),
'except' => ['options']
],
'access' => [
'class' => AccessControl::className(),
'rules' => [
[
'allow' => true,
'actions' => ['meters'],
'roles' => ['#'],
]
]
]
Action AccountController::actionMeters looks:
public function actionMeters($accountId)
{
// Call MS SQL procedure
$meters = Yii::$app->db->createCommand("EXEC [getMetersByAccountId] :accountId")->bindValue(':accountId', $accountId)->queryAll()
return $meters;
}
But in this way authenticated user can get (if modify GET accountId parameter) meters, which belongs to another user.
I have a user_account table in database, which link users and accounts, but I don't know in which place of application should I perform a checking properly.
How to make a check if authenticated user has an access to this resource by specified accountId parameter?
Thank you.

I've found solution to determine matchCallback in access rule. Now it's look:
[
'allow' => true,
'actions' => ['meters'],
'roles' => ['#'],
'matchCallback' => function() {
return Yii::$app->user->identity->user->hasAccount(Yii::$app->request->get('accountId'));
}
],
And define hasAccount method in User model:
public function hasAccount($accountId) {
return $this->hasOne(UserAccount::className(), ['user_id' => 'id'])->where(['account_id' => $accountId])->exists();
}
It's work correct. Is it a proper solution?
